Duplex printing and copying: Two-sided printing and copying (printing on both sides of the paper). ADF duplex scanning: The ADF has an automatic duplexer for scanning two-sided documents. ● Output Standard output bin: The standard output bin is located on the left side of the MFP. This bin can hold up to 500 sheets of paper. ADF output bin: The ADF output bin is underneath the ADF input tray. The bin holds up to 50 sheets of paper, and the MFP automatically stops when this bin is full.
Minimum system requirements for e-mail functionality To use the e-mail functionality, the MFP must be connected to an IP-based network that has a simple mail transfer protocol (SMTP) server. This server can either be on the local area network or at an outside Internet service provider (ISP). HP recommends that the MFP be located on the same local area network (LAN) as the SMTP server. If using an ISP, connect to the ISP by using a digital subscriber line (DSL) connection.
MFP parts and accessories Before using the MFP, become familiar with the parts of the MFP.

Media specifications This section provides comprehensive information on supported media types. Category Specifications Acid content 5.5 pH to 8.0 pH Caliper 0.094 mm (3.0 to 7.0 mils) Curl in ream Flat within 5 mm (0.02 inches) Cut edge conditions Cut with sharp blades that create no visible fray Fusing compatibility Must not scorch, melt, offset, or release hazardous emissions when heated to 200°C (392°F) for 0.
Envelopes Envelope construction is critical. Envelope fold lines can vary considerably, not only between manufacturers, but also within a box from the same manufacturer. Successful printing on envelopes depends upon the quality of the envelopes. When selecting envelopes, consider the following components: ● Weight: The weight of the envelope paper should not exceed 105 g/m2 (28 lb) or jamming might occur. ● Construction: Prior to printing, envelopes should lie flat with less than 6 mm (0.
Envelopes that have double side seams Double side-seam construction has vertical seams at both ends of the envelope rather than diagonal seams. This style might be more likely to wrinkle. Be sure that the seam extends all the way to the corner of the envelope, as illustrated. Envelopes that have adhesive strips or flaps Envelopes that have a peel-off adhesive strip or with more than one flap that folds over to seal must use adhesives that are compatible with the heat and pressure in the MFP.
Labels CAUTION To avoid damaging the MFP, use only labels that are recommended for use in laser printers. Never print on the same sheet of labels more than once or print on a partial sheet of labels. Label construction When selecting labels, consider the quality of each component: ● Adhesives: The adhesive material should be stable at 200°C (392°F), the MFP's fusing temperature. ● Arrangement: Only use labels that have no exposed backing between them.
Supported types and sizes of print media The following table lists the types of media that the MFP supports.

Check the MFP software for supported sizes. Capacity can vary depending on paper weight and thickness, as well as environmental conditions. Face-down delivery only.
Printing on special media Use these guidelines when printing on special types of media. NOTE Special media such as envelopes, transparencies, custom-size media, or heavy media greater than 120 g/m2 should only be used in Tray 1. To print on any special media, use the following procedure: 1. Load the media in Tray 1. 2. When the MFP prompts you for the paper type, select the correct media type for the media loaded in the tray.
Colored paper ● Colored paper should be of the same high quality as white xerographic paper. ● Pigments used in colored media must be able to withstand the MFP’s fusing temperature of 190° C (374°F) for 0.1 second without deterioration. ● The MFP creates colors by printing patterns of dots, overlaying and varying their spacing to produce various colors. Varying the shade or color of the paper will affect the shades of the printed colors. Envelopes NOTE Envelopes can be printed only from Tray 1.
Heavy paper The following heavy paper types can be used with the HP Color LaserJet 4730mfp series MFP. Table 1-14 Supported heavy paper types Paper type Paper weight Heavy and extra-heavy stock 105-163 g/m2 (28-43 lb) Cardstock 164-220 g/m2 (43-58 lb) Intermediate 90-105 g/m2 (24-28 lb) HP Tough paper 5 mil When printing on heavy paper types, use the following guidelines: ● Use Tray 1 for paper that is heavier than 120 g/m2 (32 lb).
● Forms and letterhead should be sealed in a moisture-proof wrapping to prevent changes during storage. ● Before loading preprinted paper such as forms and letterhead, verify that the ink on the paper is dry. During the fusing process, wet ink can come off of preprinted paper. ● To load pre-printed forms and letterhead into Tray 1, load them face down with the top edge of the page facing toward you.

5 Theory of operation This chapter provides information about the following topics: ENWW ● Basic operation ● Formatter system ● Engine control system ● Laser/scanner system ● Image formation system ● Pickup/feed system ● Scanner system ● 2 X 500-sheet paper feeder ● Output devices 141
Basic operation The HP Color LaserJet 4730mfp functions are divided into the following systems: ● Engine control system ● Laser/scanner system ● Image formation system ● Pickup/feed system ● Scanner system ● 2 X 500-sheet paper feeder ● Output devices The engine control system controls the laser/scanner system, the image formation system, and the pickup/feed system.
Operation sequence A microcomputer in the engine control system controls the operation sequence for the MFP. The basic operation sequence (see Table 5-1 Basic operation sequence on page 143) describes the main operational periods from the point when the MFP is turned on until a print operation is completed and each motor stops rotating. NOTE In the following table, “ETB” stands for “electrostatic transfer/transport belt.
Period (sequence) Description Standby The period of time from the end of the initialization sequence until a request for a scan. During this time, the MFP might go into Sleep mode and the scan carriage rests in its home position. Scan The period of time immediately following a request for a scan. The scanner fan turns on, the scan start position is adjusted, the MFP performs the scan, and data is sent to the formatter.

Formatter system The formatter PCB is responsible for the following actions: ● Receiving and processing print data from the various MFP interfaces ● Monitoring control panel inputs and relaying MFP status information (through the product control panel and the bidirectional I/O) ● Developing and coordinating data placement and timing with the print engine ● Storing font information ● Communicating with the host computer through the bidirectional interface ● Controlling the Sleep mode The formatte
downloadable fonts, and macros. The default setting is 30 MINUTES. You can turn Sleep mode off in the CONFIGURE DEVICE menu, under RESETS. The MFP exits Sleep mode and enters the warm-up cycle when any of the following occurs: ● A print job, valid data, or a PML or PJL command is received at the parallel port, EIO card, or USB 2.0 connector. ● A product control panel button is pressed. ● The right upper and lower covers are opened. ● The engine test button is pressed.
Flash Optional flash is available in 4 MB flash memory DIMMs for storing forms, fonts, and signatures. Hard disk The hard disk is mounted in an EIO slot on the formatter. The hard disk is used to create multiple original prints (mopies) and store forms, fonts, and signatures. CPU The HP LaserJet 4730mfp formatter incorporates a 533 MHz RISC processor. FIH (foreign interface harness) The FIH allows connection to third-party devices, such as copy counters and biometric security devices.
Nonvolatile memory The MFP uses nonvolatile memory (NVRAM) to store I/O and information about the print environment configuration. The contents of NVRAM are retained when the MFP is turned off or disconnected. PJL overview Printer job language (PJL) is an integral part of configuration, in addition to the standard printer command language (PCL).
Engine control system The engine control system is the brain of the HP Color LaserJet 4730mfp. It controls all the other systems according to commands from the formatter. The engine control system consists of the following: ● DC controller PCB ● High-voltage PCB ● Low-voltage power supply PCB ● Formatter Each of these components is described in this chapter.
Figure 5-5 DC controller PCB ENWW Engine control system 151
Block operation The blocks that make up the DC controller PCB include: ● CPU. The CPU is a single-chip microcomputer with built-in ROM and RAM. It controls the MFP engine sequence, ASIC, fuser, pickup motor and lifter motor, solenoids, sensors, and switches. ● ASIC. Interfaces with the IC, memory, and external devices. ● Motor driver ASIC. Controls each motor in response to commands from the CPU. ● Reset IC. Monitors voltage and resets the CPU and ASIC when the power is turned on. ● EEPROM.

Drum motor failure detection The DC controller determines the drum motor failure and notifies the formatter of an error status when it encounters the following conditions. NOTE The drum motor failure detection operates in the same manner for each color separately. ● Drum motor start-up abnormality. The interval of the drum motor speed detection signal does not reach the specified interval after 1.5 seconds of the drum motor drive start. ● Drum motor rotation abnormality.
Power supply fan failure detection The DC controller detects a power supply fan failure and notifies the formatter of an error status when the power supply fan lock detection signal is input for ten seconds continuously. Scanner fan failure detection The DC controller detects a scanner fan failure and notifies the formatter of an error status when the scanner fan lock detection signal is input.
Figure 5-7 Low-voltage power supply circuits Fuser control circuit This MFP uses a ceramic heating method to heat the fuser. Figure 5-8 Fuser power supply circuit on page 157 shows the configuration of the fuser power supply.
The fuser power supply system has three main components: ● Fuser heater. A ceramic heater heats the fuser sleeve. The heater has a U-shaped heating element on its surface. ● Thermistors. Two thermistors are in the fuser sleeve: one in the center, and the other at the end. Each thermistor monitors the temperature in the fuser sleeve. ● ● Main thermistor. The main thermistor controls print temperature and between-sheets temperature.
Table 5-3 Fuser temperatures (continued) Media Temperature Engine speed Tough paper ~ 180°C (356°F) 1/3 Envelopes ~ 180°C (356°F) 1/2 Low-voltage power supply circuit The low-voltage power supply circuit converts AC power from the wall receptacle into DC power to cover the DC loads. Figure 5-9 Low-voltage power supply circuit The AC power is supplied to the low-voltage power supply circuit by turning on the power switch (SW101). The AC power is then converted into +24V, +5V and +3.
Protective functions Two fuses, FU101 and FU102, protect against overcurrent and overvoltage to prevent failures in the power supply circuit. If there is a supply error, such as a short-circuit or overvoltage, the low-voltage system automatically cuts off the output voltage. The fuses blow and cut off the AC power, once AC overcurrent flows into the AC line. If DC voltage is not being supplied from the low-voltage power supply circuit, turn off the power switch (SW101).
Figure 5-10 Heater temperature control circuit The fuser heater temperature is monitored by two thermistors: the main thermistor (TH1) and the sub thermistor (TH2). The main thermistor controls the print temperature and the between-sheets temperature. The sub thermistor detects the one-sided temperature rise of the fuser heater, and controls the initial rotation temperature and the start-up temperature. The CPU (IC1101) on the DC controller monitors the voltage of the fuser heater temperature signals.
Print temperature control This control maintains the temperature of the fuser sleeve at its targeted temperature during the printing operation. The CPU gradually raises the targeted temperature in one printing process. This prevents the fuser temperature from falling while the media goes through the fuser roller. The targeted temperature also varies according to the number of prints when continuous printing. The targeted temperature varies depending on the media types.
Protective function by the thermoswitch When the temperature of the fuser heater rises abnormally high and the detected temperature of the thermoswitch (TP) exceeds approximately 250°C (482°F), the thermoswitch is disconnected and the power supply to the fuser heater is immediately cut off. NOTE The actual temperature of the fuser heater is about 30° higher than the thermoswitch, as the thermoswitch is not contact with the fuser heater.
● If the detected temperature of the main thermistor is kept 120°C (248°F) or lower for 0.5 seconds continuously, from when the media reaches the fuser until the heater is turned off during the print period. ● If the detected temperature of sub thermistor is kept 50°C (122°F) or lower for 0.5 seconds continuously during the standby period.
Figure 5-11 High-voltage power supply block diagram Generation of biases Generation of primary charging bias: The primary charging bias is the DC negative bias that is generated to apply negative potential to the photosensitive drum in preparation for image formation. This bias is generated for each color (Y, C, M, K) in the primary charging high-voltage power supply circuit.
The developing voltage (bias) causes the toner to adhere to the electrostatic image that the laser/ scanner assembly created on the photosensitive drum. Two types of developing biases are used: the developing DC negative bias and the developing AC bias. The high-voltage circuit on the power supply generates both biases. These biases are superimposed on one another and then applied to the primary charging roller, which transfers the biases to the drum.
Sub power supply assembly The sub power assembly provides power to the ADF and the image scanner. It is connected to the low-voltage power supply and the DC controller. Video interface control The video interface allows communication between the formatter and the DC controller. The formatter always monitors the status of the MFP by using the video interface. It sends the VIDEO signals to the DC controller through the video interface when the MFP is ready to print.
168 7. The latent images on the photosensitive drums are developed by toner and transferred onto paper in this order: Y (yellow), C (cyan), M (magenta), and K (black). 8. The toner is fused to the paper in the fuser and the paper is delivered to the delivery tray. Printing continues if the DC controller receives another print command from the formatter during the printing operation.
Laser/scanner system The laser/scanner system forms the latent electrostatic image on the photosensitive drum according to video signals sent from the formatter. The main components of each laser/scanner assembly are the laser driver, scanner motor, mirrors, and focusing lenses. Each color has its own laser/scanner assembly unit, which is controlled by the DC controller.
5. The laser beams are reflected by the six-faced mirror, pass through the focusing lens and the reflecting mirror that is in front of the six-faced mirror, and focus the photosensitive drum. 6. While the six-faced mirror rotates at a constant speed, the laser beams on the photosensitive drum scan the drum. 7. As the photosensitive drum rotates and the laser beams scan on the photosensitive drum, both at a constant speed, a latent image is formed the drum.
Figure 5-14 Laser control circuit block diagram The laser control circuit manages the following control and detection functions: ● Laser emission control. Allows the laser diodes to turn on and off according to the video signals sent by the formatter. ● Automatic power control (APC). Allows the laser diodes to emit light at a constant intensity. ● Horizontal synchronous control. Aligns the starting position in the horizontal direction. ● Image masking control.
The DC controller divides the oscillation frequency of the oscillator (X1201) and generates the reference clock signal. It compares the intervals between the reference clock signal and the BD input signal (/BD1I) with the frequency comparator, and monitors the rotational count of the scanner motor. The DC controller controls rotational speed by sending an acceleration signal (/SCNACC1) or deceleration signal (/SCNDEC1) to the scanner motor driver based on the detected rotational speed.
Image formation system The image formation system is the central hub of the MFP. It also forms the toner image on the media. The image formation system consists of four cartridges, the ETB, and the fuser, which are controlled by the DC controller. Figure 5-16 Image formation system on page 173 shows the image formation system.
Image formation process The image formation process consists of nine steps divided among five functional blocks: 1. Electrostatic latent image formation block. Forms an electrostatic latent image on the photosensitive drum. Step 1: Pre-exposure Step 2: Primary charging Step 3: Laser beam exposure 2. Development block. Makes the electrostatic latent image on the photosensitive drum surface visible by applying toner. Step 4: Development 3. Transfer block.
Figure 5-17 Image formation process ENWW Image formation system 175
Electrostatic latent image formation block The image formation process begins in the electrostatic latent image formation block. This block consists of three steps that results in forming an electrostatic latent image on the photosensitive drum: ● Pre-exposure ● Primary charging ● Laser beam exposure When the last step in this block is complete, areas of the drum surface that have not been exposed to the laser beam retain a negative charge.
Step 2: Primary charging To prepare for latent image formation, the surface of the photosensitive drum is charged with a uniform negative potential. The charging method of this MFP is to charge directly to the photosensitive drum surface from the primary charging roller, which is interlocked with the drum. The primary charging roller is made of a conductive rubber. To charge the drum surface negatively, the DC bias is applied to the primary charging roller.
Transfer block The third part of the image formation process is the transfer block, in which the toner image is transferred from the photosensitive drum to the media. This block consists of three steps: ● Attraction ● Transfer ● Separation Step 5: Attraction To feed the media vertically, it is necessary to push the media against the ETB. The picked up media is fed as it is pushed against the ETB by the attraction roller.
ETB Paper Transfer roller Photosensitive drum DC bias Figure 5-22 Toner transfer Step 7: Separation The elasticity of media separates the media from the photosensitive drum and the ETB. ETB Paper ETB feed roller Figure 5-23 Separation Fusing block The fourth part of the image formation process is the fusing block, in which the toner image is fused to the media, making a permanent image that cannot be smeared. This block consists of one step: fusing.
Figure 5-24 Fusing Cleaning block The fifth and final part of the image formation process is the cleaning block, in which the photosensitive drums are cleaned, preparing them for the next print. In the transfer block, not all of the toner is transferred from the photosensitive drum onto the media, but some remains on the drum surface. This remaining toner is called residual toner or waste toner. The cleaning block cleans the photosensitive drum surface to keep a clear image in the next print.

The DC controller controls the color misregistration unit under the following conditions: ● At power on or door close after cartridge replacement ● After job completion in every specified number of printings ● At a command from the formatter The following is the operational sequence of the color misregistration corrective control: 1. The DC controller forms two pattern images for color misregistration detection with four colors on the ETB when the color misregistration corrective control starts.
ETB LED DRIVE signal Color misregistration pattern image COLOR MISREGISTRATION signal DC controller PCB Color misregistration sensor (R) Pattern image Color misregistration sensor (L) Light emitter (LED) COLOR MISREGISTRATION signal Light receiver (PD) Figure 5-31 Color misregistration detection The DC controller notifies the formatter of each error when the following errors are found during the color misregistration detection.
Figure 5-32 Image stabilization control Environmental change control This control calibrates each bias to obtain the best image possible according to environmental changes. The environmental sensor detects the temperature and the humidity. The sensor sends this information to the DC controller in the form of the temperature detection signal (TEMSNS) and the humidity detection signal (HUMSNS). The DC controller monitors the environmental conditions of the MFP based on these two signals.
The DC controller controls the following biases to prevent image defects when it detects an environmental change: ● Developing bias ● Primary transfer bias ● Secondary transfer bias If the environment sensor detects a temperature of below -30ºC (22ºF) or over 80ºC (176ºF), the DC controller determines this is an "environment sensor abnormality" and sends an error message to the formatter.
The following is the operational sequence of the image density control: 1. The DC controller allows the LED to emit light by sending the LED drive signal. The image density detection control starts. 2. The density pattern images on the ETB reflect the light from the LED and the PD in the sensor receives the light. This reflected light intensity differs depending on the toner density. 3.
Pickup/feed system The pickup/feed system consists of various feed rollers that pick up and feed media. This MFP has four pickup sources: the MP tray, tray 2, and the two trays of the 2 X 500-sheet paper feeder. The primary delivery source is the face-down tray. The IPTU and stapler/stacker or 3-bin mailbox can also be used for output. The multipurpose tray paper sensor (SR4) detects the media presence in the multipurpose tray, and the cassette paper sensor (SR9) detects the media presence in the cassette.

From the point the media is picked from the tray until it reaches the fuser.
Pickup/feed unit The pickup/feed block is structured with two blocks. One is the pickup block, which picks up media from the cassette or the multipurpose tray into the MFP one by one. The other one is the feed block, which feeds the picked-up media to the fuser. The following sequence of events occurs: 1. The DC controller rotates the pickup motor (M9), drum motors (M1, M2, M3, M4), ETB motor (M7), and fuser motor (M5) after receiving a print command from the formatter. 2.
The paper leading-edge sensor detects when the leading edge and the trailing edge of a sheet pass it. By measuring the time between the passing of the leading edge and trailing edge, the sensor can determine the actual size of the sheet. If this measured size differs from the size specified by the formatter or the switch combination, the DC controller determines a mismatch. The sheet is ejected from the MFP, and the MFP stops.
the media stack is loaded. The DC controller monitors the cassette paper sensor (SR9) and the media stack surface sensor (SR10) when the MFP is turned on, the cassette is installed, and during the printing operation. The media lifting operation is divided into two procedures: ● Initial lift ● Lifting during printing Initial lift The initial lift begins when the cassette is installed in the MFP and the lifting plate remains in the bottom of the cassette.

3. The fusing sleeve and the fusing pressure roller fuse the toner onto the media. The media is then delivered from the fuser. 4. The image fusing media sensor (SR1) detects the media delivered from the fuser, and then delivers the media to the face-down tray or other output device. NOTE If the face-down tray is full of media, the delivery tray paper-full sensor (SR2) detects that it is full.
Figure 5-42 Loop control Fusing pressure release mechanism This mechanism automatically releases the fusing pressure to improve media removal and prevent fusing pressure roller deformation. The DC controller rotates the cam driven by the fuser pressure release motor (M6) at the prescribed timing. The lifting plate is pushed down and the fusing pressure roller is released.
Figure 5-43 Fusing pressure release Duplex feed unit This MFP is equipped with an integrated duplexing unit. The duplexing reverse/duplexing feed unit is structured into two blocks. One is the duplexing reverse block, that reverses paper in preparation for duplex printing. The second is the duplexing feed block, which delivers the reversed paper to the registration roller.
Duplexing unit Figure 5-44 Duplex feed unit The duplexing driver PCB controls the duplexing unit. An 8-bit microcomputer in the duplexing driver PCB controls the sequences of the duplexing unit and serial communication with the DC controller. The DC controller sends a command to the duplexing driver PCB at the necessary time. The duplexing driver PCB drives each load, such as motors and solenoids, depending on these commands.
Figure 5-46 Duplexing feed ENWW 1. Media that has been printed on one side passes through the fuser. 2. The DC controller sends the reversing command to the duplexing driver at the specified time after the top of page sensor (SR12) detects the leading edge of paper. The prescribed time is when the media arrives at the fuser.
3. When the duplexing driver receives the reversing command, it turns on the duplexing solenoid (SL8001) to move the duplexing deflector. The duplexing driver also rotates the reversing motor (M8001) clockwise to feed the media to the duplexing unit. 4. The DC controller sends the duplexing pickup command to the duplexing driver after the prescribed time from when the fuser paper sensor (SR1) detected the trailing edge of paper.
● Delivery tray paper-full sensor (SR2) ● Reversing paper sensor (SR8001) The microprocessor on the DC controller checks for jams by timing the media as it moves past these sensors. If the media does not pass the sensor in a specific period of time, the transport process is stopped (the motors are turned off and the rollers no longer rotate) and a jam message displays on the product control panel display.
Residual paper jam If the fuser paper sensor (SR1) detects paper during the WAIT or INTR period, or if the top-of-page sensor or fuser paper sensor detect paper during the automatic delivery period, the microprocessor on the DC controller PCB determines that a residual paper jam has occurred. The transport process stops and a 13.XX.YY JAM message displays on the product control panel display. For more information about jam messages, see Resolving control panel messages on page 478.
Scanner system The scanner system adds copying and sending functions to the standard MFP printing function. The scanner assembly consists of an automatic document feeder (ADF) and a flatbed scanner glass surface. Original documents that are fed through the ADF are delivered to the ADF output bin, which is underneath the ADF input tray. Printed copies are delivered to the output device that is attached to the print engine. The scanner unit has built-in duplexing capability for scanning two-sided documents.
Figure 5-49 Scanner assembly electrical structure Motors and fans The scanner assembly has five motors and two fans. Three of the motors are stepping motors, which drive the components inside the scanner assembly. The remaining two motors are DC motors, which drive the two fans.
Name Purpose Type Rotation Failure detection Flatbed fan Cools the scanner lamp and the CCD DC motor Clockwise Yes ADF fan Cools the motors DC motor Clockwise Yes Optical assembly The optical assembly contains the scan carriage and the scanner glass. The scan carriage contains the lamp, five mirrors, a lens, and the CCD. Figure 5-50 Scan carriage components The scanner lamp illuminates a small strip of the document (called the raster line).
Figure 5-51 Scan carriage movement ADF feed system Pages from the original document enter the ADF from the ADF input tray. A separation roller and separation pad work together to separate the top sheet from the stack. The page passes through a set of registration rollers and two sets of feed rollers that advance the page. A set of delivery rollers delivers the page to the ADF output bin. A bin-full sensor detects when the ADF output bin is full, and stops the feed mechanism until the bin is emptied.
Figure 5-52 ADF paper path and sensors ADF jam detection When the sensors inside the ADF detect a jam, the feed and read motors immediately stop and send a signal to the scanner controller PCB, which notifies the formatter. An ADF PAPER JAM message displays on the product control panel display. To clear a jam, open the jam access cover and remove the media. If no sensors detect media after the jam access cover is closed, the jam message is cleared from the product control panel display.
Registration sensor jam If the registration sensor does not detect the trailing edge of the media after the leading edge reaches the scan ready position, the scanner controller PCB determines that an ADF paper jam has occurred. Also, when the scanner duplexer is being used, if the registration sensor does not detect the leading edge of the media after a specific period of time after media enters the duplexer, the scanner controller PCB determines that a jam has occurred.
2 X 500-sheet paper feeder The MFP includes a 500-sheet paper tray (tray 2) and a larger paper deck that contains two 500sheet feeders (trays 3 and 4). The paper path is shown below. Figure 5-53 2 X 500-sheet feeder paper path The paper feeder driver PCB controls the 2 X 500-sheet feeder operation sequences. The microprocessor in the paper feeder driver controls the 2 X 500-sheet feeder sequences and the communication with the DC controller PCB.
Figure 5-54 2 X 500-sheet feeder I/O block diagram Pickup and feed operations The paper pickup and feeding processes for the 2 X 500-sheet feeder are identical to the processes used for tray 2. See Figure 5-54 2 X 500-sheet feeder I/O block diagram on page 222. The Figure 5-55 2 X 500-sheet feeder pickup and feed diagram on page 223 identifies the components of the 2 X 500-sheet feeder.
Figure 5-55 2 X 500-sheet feeder pickup and feed diagram ENWW 1. The DC controller receives a print command from the formatter and sends a pickup command to the paper feeder driver. 2. The paper feeder driver rotates the pickup motor (M8101) in the paper feeder, and the feed roller and the paper feeder separation roller start to rotate. 3. The DC controller sends the paper feeder pickup start command to the paper deck driver PCB after the scanner is ready. 4.
NOTE Paper-size detection, multiple-feed prevention, and jam detection for the 2 X 500sheet feeder function in the same manner as the rest of the MFP. NOTE Paper lifting operation for the 2 X 500-sheet feeder is the same as that of tray 2, except that the paper feeder driver PCB controls this operation instead of the DC controller. 2 X 500-sheet jam detection The paper feed sensor (SR8201) detects abnormal feed operation in the 500-sheet paper feeder.
Output devices This section describes the theory of operation for these components: ● IPTU ● 3-bin mailbox ● Stapler/stacker IPTU The IPTU (intermediate paper transfer unit) is installed at the face-down delivery area of the MFP. Its function is to transfer paper to the installed output device, such as the stapler/stacker and the 3-bin mailbox. The standard face-down tray should be removed when installing the IPTU. Paper flow is illustrated in Figure 5-56 IPTU paper path on page 225.

The DC controller sends the drive start command to the IPTD when the fusing paper sensor (SR1) detects the leading edge of the paper. 3.
IPTU jam detection The IPTU is equipped with paper detection sensors to detect the presence of paper and to determine operational status: ● Top of page sensor (SR8301) ● Delivery sensor (SR8302) The CPU on the IPTD PCB determines a paper jam by checking whether paper is present at the sensors at the checking timing. The checking timing is stored in the memory of the CPU. If the CPU determines a jam, it stops the intermediate paper transfer operation and notifies the MFP of the jam.
Figure 5-59 3-bin mailbox operation ENWW Output devices 229
Stacker mode When configured for stacker mode, the 3-bin mailbox fills the bottom output bin (bin 3) first and then fills the next highest bin. Figure 5-60 Media flow when using the stacker mode Mailbox mode When configured for mailbox mode, the 3-bin mailbox stacks print media in each bin as determined by the print job specifications. For example, one user might have all jobs delivered to the bottom bin, and another user might have all jobs delivered to the top bin.
Feed stationary jam If the inlet sensor (PS1501) does not detect the trailing edge of the media within a specific time period after it detects the leading edge, the microprocessor on the MBM driver PCB determines that a feed stationary jam has occurred. Residual media jam If the inlet sensor (PS1501) detects the presence of media during the initial WAIT period, the microprocessor on the MBM driver PCB determines that a residual media jam has occurred.
Figure 5-61 Stapler/stacker operation 232 Chapter 5 Theory of operation ENWW
Staple mode When the print job specifications require stapling, the pages of the document are gathered inside the unit. A jogger aligns the pages horizontally, and a paddle aligns the pages vertically. When all pages of a job are gathered, a clamp compresses the stack and a staple is attached. After the document is stapled, the jogger guides spread apart to release the stack, and the stapled document falls into the stacker bin.
Feed stationary jam If the inlet sensor (PS1301) does not detect the trailing edge of the media within a specific time period after it detects the leading edge, the microprocessor on the MBM driver PCB determines that a feed stationary jam has occurred.

7 Troubleshooting In order to use the information in this chapter, you should have a basic understanding of the HP LaserJet printing process. Explanations of each mechanical assembly, the MFP systems, and the basic theory of operation are contained in chapter 5 of this manual. Do not perform any of these troubleshooting processes unless you understand the function of each MFP component.
Introduction The information in this troubleshooting chapter is presented with the assumption that the reader has a basic understanding of the color laser-printing process. Explanations of each mechanical assembly, printer systems, and the basic theory of operation are provided in chapter 5. Do not perform any of these troubleshooting processes without fully understanding the function of each mechanism.
Troubleshooting process When the MFP malfunctions or encounters an unexpected situation, information on the control panel alerts you to the situation. This section contains an initial troubleshooting checklist that helps to eliminate many possible causes of the problem. The subsequent troubleshooting flowchart helps you to diagnose the cause of the problem. The remainder of the chapter provides steps for correcting the problems that have been identified.
5. 6. 7. If the configuration page prints, check the following items. a. If the page prints correctly, then the MFP hardware is working. The problem is with the computer that you are using, with the printer driver, or with the program. b. If the page does not print correctly, the problem is with the MFP hardware. See Functional checks on page 586. Does the image quality meet the user's requirements? If yes, go to step 7.
Troubleshooting flowchart This flowchart highlights the general processes that you can follow to quickly isolate and solve MFP hardware problems. Each row depicts a major troubleshooting step. A “yes” answer to a question allows you to proceed to the next major step. A “no” answer indicates that additional testing is needed. Proceed to the appropriate section in this chapter, and follow the instructions there.
Table 7-1 Troubleshooting flowchart (continued) See Network connectivity problems on page 584. Also see Configuring and verifying an IP address on page 133 in chapter 3 of this manual. If error messages appear on the control panel display, see Resolving control panel messages on page 478. When the customer can print from the host computer, this is the end of the troubleshooting process.
Power-on checks The basic MFP functions should start up as soon as the MFP is plugged into an electrical outlet and the power switch is pushed to the on position. If the MFP does not start, use the information in this section to isolate and solve the problem. Power-on troubleshooting overview Turn on the MFP power. If the control panel display remains blank, random patterns appear, or asterisks remain on the display, perform power-on checks to locate the cause of the problem.
Control panel messages Messages that appear on the control panel display relay the normal status of the MFP (such as Processing job.), or an error condition (such as CLOSE TOP COVER) that needs attention. Resolving control panel messages on page 478 lists messages that require attention, or that might raise questions. Messages are listed in alphabetical order, with numeric messages at the end of the list. Not all messages are listed because some (such as READY) are self-explanatory.

Correcting print quality and copy quality problems This section helps to define print quality problems and how to correct them. Often print quality problems can be handled easily by making sure that the MFP is properly maintained, using print media that meets HP specifications, or running a cleaning page. Print quality problems associated with media Some print quality problems arise from use of inappropriate media. ● Use paper that meets HP paper specifications. See Media specifications on page 18.
● The selected colors are undesirable when printed. Select different colors in the software application or printer driver. ● If you are using a reflective overhead projector, use a standard overhead projector instead. ● The media sensing feature might not be selected. Select the feature at the control panel. Print quality problems associated with the environment The MFP is operating in excessively humid, dusty, or dry conditions. Verify that the printing environment is within specifications.
● Environmental changes can cause color variation. The development process places a high potential across an air gap to attract toner to the imaging drum. Changes in relative humidity vary the point at which the toner travels to the imaging drum. ● All consumable components have a finite life span. As these components reach the end of their useful life, their ability to produce consistent print quality diminishes. ● Paper roughness can cause colors to look different. Use standard paper.
Color options Color options enable optimal color output automatically for diverse types of documents. Color options use object tagging, which allows optimal color and halftone settings to be used for different objects (text, graphics, and photos) on a page. The printer driver determines which objects are used on a page and uses halftone and color settings that provide the best print quality for each object. Object tagging, combined with optimized default settings, produces great color out of the box.
Halftone options Halftone options affect the resolution and clarity of your color output. You can select halftone settings for text, graphics, and photographs independently. The two halftone options are Smooth and Detail. ● The Smooth option provides better results for large, solid-filled print areas. It also enhances photographs by smoothing out fine color gradations. Choose this option when uniform and smooth area fills are top priority.
Adjusting color balance This MFP features automatic color calibration to provide high-quality color output. In situations that require critical color control, you can manually adjust the density balance of the four toner colors. The available range for each color is from -5 to +5. The default value is 0. CAUTION This procedure should only be performed by your network administrator. Performing this procedure changes the color balance of the MFP by altering halftones, and affects all print jobs.
Some swatch books are created from spot colors. Spot colors are specially created colorants. Many of these spot colors are outside of the gamut of the printer. Most spot color swatch books have companion process swatch books that provide CMYK approximations to the spot color. Most process swatch books have a note about what process standards were used to print the swatch book. In most cases they will be SWOP, EURO, or DIC.

Table 7-36 Important information on the configuration pages (continued) Type of information Engine cycles and event logs Specific information Configuration page Duplex unit Look on the main configuration page, under “Paper Trays and Options.” Additional 500-sheet feeders and optional output devices Look on the main configuration page, under “Paper Trays and Options.” Engine cycles Look on the main configuration page, under “Device Information.
Supplies status page Use the supplies status page to obtain information about the print cartridges that are installed in the MFP, the amount of toner that remains in the print cartridges, and the number of pages and jobs that have been processed. The page also lets you know when you should schedule the next preventive maintenance for each maintenance kit. NOTE The MFP has two separate maintenance kits: one is for the print engine, and the other is for the ADF.
634 1 Black Cartridge indicates the part number, amount of toner remaining in the print cartridge, estimated pages remaining, total number of pages and jobs processed, print cartridge serial number, and date installed and last used. 2 Cyan Cartridge indicates the part number, amount of toner remaining in the print cartridge, estimated pages remaining, total number of pages and jobs processed, print cartridge serial number, and date installed and last used.
Usage page The usage page provides information about the page sizes and number of pages printed, copied, and sent.
636 1 Device Information indicates the device name and serial number. 2 Usage Totals: Printed (Print, Copy & Fax) indicates types of pages that have been printed; the number of singlesided pages that have been printed; the number of duplexed pages that have been printed; the total number of copies made; and the total number of fax pages printed.
PCL or PS font list Use the font lists to see which fonts are currently installed in the MFP. (The font lists also show which fonts are resident on a hard disk or flash DIMM.) The PS font list shows the PS fonts installed, and gives a sample of those fonts. The following describes the information that can be found on the PCL font list: ● Font gives the font names and samples. ● Pitch/Point indicates the pitch and point size of the font.
Individual component diagnostics From the diagnostics menu, you can run tests to check the status of various components in the MFP. During many of the diagnostic tests, the MFP enters a special diagnostics mode, which allows you to send print jobs and interact with the menus. The MFP stays in this mode until you press Stop and then touch EXIT DIAGNOSTICS at the top of the DIAGNOSTICS menu. In some cases, the MFP must re-initialize after performing a component-level diagnostic test.
Figure 7-12 Formatter LED Engine diagnostics This section provides an overview of the engine diagnostics that are available in the HP Color LaserJet 4730mfp series MFP. The MFP contains extensive internal diagnostics that help in troubleshooting print quality, paper path, noise, component, and timing issues. Diagnostics mode Some of the diagnostic tests automatically put the MFP into a special diagnostics mode.
Diagnostic tests Different tests can be used to isolate different types of issues. For component or noise isolation, you can run the diagnostic test after removing the covers. Removing the covers provides a better view of the areas that are being tested. To operate the MFP with the covers removed, the door switch (SW4, callout 1) lever must be depressed (this is the door-closed position). WARNING! Be careful when performing MFP diagnostics to avoid risk of injury.
Paper path sensor test The paper path sensor test checks for the presence of media at each of the sensors along the paper path. After you have selected this test from the DIAGNOSTICS menu, you can print internal pages or send a print job from a computer. As the media passes each sensor, the sensor's state is updated. On the control panel display, each sensor is represented by a string of alphabetic letters followed by a corresponding status for each sensor.
Manual sensor test The manual sensor test indicates the status of the sensors and switches in the MFP. On the control panel display, each sensor is represented by a string of letters followed by a corresponding status for each sensor. Except for the paper size switches, a “0” next to the letter indicates that no media is present or the switch is open. A “1” indicates that media is present or the switch is closed.
ENWW ● 7 = heavy ● 8 = light ● A = extra heavy glossy Tools for troubleshooting 643
Scanner tests Use the scanner tests to verify that specific components in the scanner assembly are operating correctly. For most of the components, you must observe or listen to the component in order to verify that it is functioning as stated on the control panel display. For the scanner sensors, you must activate the sensor and watch the condition indicator on the control panel display to see if it changes.

Service menu Authorized HP service technicians can use this menu to gain access to MFP settings that are reserved for service personnel. The service menu is protected by a personal identification number (PIN). When you select SERVICE from the list of menus, you are prompted to type an eight-digit PIN code. The PIN code for this MFP is 09473005. NOTE The MFP automatically exits the service menu after about one minute if no menu items are selected or changed.
Table 7-39 Service menu (continued) Item Explanation SEND SCAN COUNT Select this item to set the number of scanned pages that have been sent to e-mail. COPY PAGES COUNT Select this item to set the number of scanned pages that have been printed. SCANNER SETTINGS CAUTION The SCANNER SETTINGS are used for factory adjustments and should not be used by service personnel. Use the scanner calibration routine to adjust the scanner settings if necessary. See Calibrating the scanner on page 104.
Service ID This information appears on the configuration page, which eliminates the need for customers to keep paper receipts for proof of the warranty. Converting the service ID to an actual date You can use the MFP Service ID number to determine whether the MFP is still under warranty. Use the following procedure to convert the Service ID into the installation date. 1. Add 1990 to YY to determine the actual year that the MFP was installed. 2.
Troubleshooting the embedded HP Jetdirect print server If network-connection errors occur, you can disable the HP Jetdirect print server in order to determine if the problem is with the print server or with the network. This procedure requires that you temporarily install an optional EIO HP Jetdirect print server card while disabling the embedded HP Jetdirect print server. To disable the embedded HP Jetdirect print server 1. Turn the MFP off and then on. 2.
