Product media specifications The product accepts a variety of media. Properties such as weight, grain, and moisture content are important factors affecting printer performance and output quality. Media should conform to the guidelines in the User Guide located on the product CD. Media that does not meet HP guidelines might cause poor print quality, increased media jams, or premature wear on the product. This may require repair.
Guidelines for using media Paper and Transparencies Paper must be of good quality and free of cuts, nicks, tears, spots, loose particles, dust, wrinkles, holes, and curled or bent edges. Check the label on the paper package for details about the type of paper (such as bond or recycled). Some paper causes print quality problems, jamming, or damage to the printer.
Labels When selecting labels, consider the quality of the following factors: Adhesives: The adhesive material should be stable at 200° C (392° F), the printer’s maximum temperature. Arrangement: Only use labels with no exposed backing between them. Labels can peel off sheets that have spaces between the labels, causing serious jams. Curl: Prior to printing, labels must lie flat with no more than 13 mm (0.5 in) of curl in any direction.
Envelopes with double-side seams An envelope with double-side-seam construction (vertical seams at both ends of the envelope rather than diagonal seams) is more likely to wrinkle.
Card stock construction Smoothness: 135-157 g/m2 (36-to 42-pound) card stock should have a smoothness rating of 100 to 180 Sheffield. 60-135 g/m2 (16- to 36-pound) card stock should have a smoothness rating of 100 to 250 Sheffield. Construction: Card stock should lie flat with less than 5 mm (0.2 in) of curl. Condition: Make sure that the card stock is not wrinkled, nicked, or otherwise damaged.
Note When you add new media, make sure that you remove all of the media from the input tray and straighten the stack of new media. This helps prevent multiple sheets of media from feeding through the printer at one time, reducing paper jams. Specific types of media Transparencies and labels: Load transparencies and labels with the top forward and the side to be printed facing up. See the User Guide located on the product CD for more information.
Perform the following actions to minimize the possibility of jams: Remove self-stick notes. Remove staples and paper clips. Straighten any curls, folds, or wrinkles in documents before putting them into the document feeder tray. Do not insert any document with glue, correction fluid, or wet ink on it. Do not insert gum-backed paper or labels. Avoid multiple-copy forms. Do not scan originals that are larger or smaller than supported size limitations.
2 Lift the flatbed scanner cover. 3 Place the original document facedown on the flatbed scanner with the top left corner of the document located in the lower right corner of the glass. 4 Gently close the lid. 5 The document is ready to be copied or scanned. CAUTION To prevent damage to the product, do not allow the scanner lid to fall onto the flatbed scanner surface. Always close the scanner lid when the product is not in use.
EN 3 Slide the media stack into the ADF until the media does not move any farther. 4 Adjust the media guides until they are snug. 5 The document is now ready to be copied or scanned. 6 After scanning, the document will be delivered to the output tray in the correct order.
Printer output paths Output bin and straight-through output path The output bin is located between the scanner and the printer. Printed media is collected here in the correct sequence when the straightthrough output door is closed. Use the output bin when printing normal and large collated documents. The straight-through output path is useful when you are printing envelopes, transparencies, heavy media, or any media that tends to curl when printed.

HP 3300 Product ADF Scanner Formatter Printer Fax LIU Formatter Computer Scanner Printer Engine ECU Figure 10.
Formatter system The formatter coordinates the major systems.
Flash memory or ROM The formatter system includes firmware code that controls the product stored in either flash memory or ROM, depending on when the product was manufactured. Initially the formatters in all manufactured units are built with flash memory. As the product manufacturing matures, the code is stored in standard read-onlymemory (ROM). Units with firmware code in flash memory allow the firmware code to be recovered or updated. The firmware update/recovery process is described in Chapter 6.
RAM One bank of Non-Volatile RAM (NVRAM) stores parameters. Dynamic random access memory (DRAM) provides temporary storage of the product program code plus copy, scan, and print data. Parallel interface or Universal Serial Bus interface The formatter receives incoming data through its bidirectional ECP or USB interface.
Enhanced I/O The Enhanced I/O feature allows product memory to be used for storing data received from the host computer. When Enhanced I/O is enabled, you can send more data to the product in shorter amounts of time, which allows you to return to your application sooner. Enhanced I/O has the following options: Auto—allows the product to use Enhanced I/O memory allocation to increase the speed of data transfer from the host computer to the product, if necessary. The default setting is Auto.
Scanner and ADF functions and operation Scanner Functions The scanner uses a light source, a color-separation method, and a Charge Coupled Device array (CCD) to collect optical information about the document and transform that into an image file. The scanner consists of: a lamp (cold fluorescent bulb) five mirrors and a lens a CCD Scanner Glass CCFL Lamp 600 ppi CCD Lens Figure 11. Optical diagram of scanner The scanner lamp illuminates a small strip of the document (called the raster line).
The image data is collected in the scanner formatter where it is processed and sent to the formatter. The formatter then handles the image data, outputting it as a copy, sending it through the LIU as a fax, or directing it to the computer as scanner output. The image data collected is 600 pixels per inch. Each pixel has 8 bits for each of the three colors (256 “grey” levels for each color) or a total of 24 bits per pixel (24-bit color).
Lift: When no more paper is detected in the ADF input tray and the trailing edge of the last page is detected by the form sensor, the last sheet is ejected and the motor turns in a sequence which lifts the pick roller assembly to standby or “paper loading” mode again. The ADF will not function with the ADF door open. The paper path is incomplete if the ADF lid is lifted from the glass. ADF paper path and ADF sensors The following figure shows the ADF paper path.
ADF Jam Detection The ADF has two sensors that detect paper. The paper present sensor detects the presence of media in the ADF input tray. The form sensor detects media moving through the ADF. If a jam is detected, the ADF immediately stops the paper feeding and the control panel displays a jam message.
Printer functions and operation Printer functions are divided into five groups: engine control formatter image formation laser/scanner pickup and feed The following figure is a block diagram of the printer and its relationship to the ADF/scanner and LIU: ADF Scanner System LIU Computer Formatter System Figure 13.
Engine control unit/power system The engine control unit (ECU) coordinates all print engine activities, drives the laser, and coordinates print data from the formatter with the image formation process. The ECU also includes power supply and distribution circuitry. Note In several other HP LaserJet products, the ECU is also known as the controller PCA or the DC controller PCA.
The following figure shows the various ECU loads: Figure 14.
Printer engine control system Paper motion monitoring and control The ECU controls paper motion in the printer by continuously monitoring the various paper sensors and coordinating the timing with the other print processes. For a detailed explanation of paper movement and the interaction of the photo sensors and solenoid with the paper movement process, see “Printer paper-feed system” on page 94. Motor The motor is controlled by the ECU. The motor provides all of the printer paper movement.
Power system on ECU The AC, DC, and high-voltage power supply circuits are all contained within the ECU. AC power distribution The AC power circuitry supplies AC voltage whenever the power cord is connected to the AC power source. AC voltage is distributed to the DC power supply circuitry and to the AC driver circuitry, which controls AC voltage to the fuser assembly heating element. DC power distribution The DC power distribution circuitry, located on the ECU, distributes +3.
Overcurrent/overvoltage There are two overvoltage devices in this product: Fuse F101 provides overcurrent protection for the fusing system circuitry. Fuse F102 provides overcurrent protection to the printer DC power supply circuitry. You can check or replace the fuses by removing the back cover (page 164). In addition, the +24 Vdc and +3.
High voltage is disabled when the print cartridge door is open. When the left-side door is opened, the print cartridge door also opens, disabling high voltage. Figure 16.
Image formation system Laser printing requires the interaction of several different technologies including electronics, optics, and electrophotographics to provide a printed page. Each process functions independently and must be coordinated with the other printer processes. Image formation consists of seven processes: Writing stage Conditioning stage Figure 17.
The seven image-formation processes 1 Conditioning stage (primary charging)—This process applies a uniform negative charge to the surface of the drum with the primary charging roller, which is located in the print cartridge. The primary charging roller is coated with conductive rubber. An AC bias is applied to the roller to erase any residual charges from any previous image. In addition, the primary charging roller applies a negative DC bias to create a uniform negative potential on the drum surface.
EN 5 Separation stage—During this process, the media separates from the drum. To stabilize the feed system and prevent toner dropouts on the printed image at low temperature and humidity, the static eliminator reduces the charge on the back of the media. 6 Fusing stage—During this process, the heat and pressure fuse the toner into the media to produce a permanent image. The media passes between a heated fusing element and a soft pressure roller, which melt the toner and press it into the media.
Printer paper-feed system The main input tray and the priority input tray merge into one main input area. Media placed in any of these areas activates the paperout sensor (PS201), which informs the ECU that media is present. The following steps occur when the product receives a print job: Step 1 The ECU activates the laser/scanner assembly and the motor. Paper motion begins when the ECU energizes the solenoid (SL001). Step 2 The paper pickup roller rotates once.
Straight-through output door Figure 18.
Jam detection The paper-out sensor (PS201) detects the presence of media in either the priority input tray or the main input tray. The top-of-page sensor (PS402) and the paper delivery sensor (PS401) detect media moving through the printer. If a jam is detected, the ECU immediately stops the printing process and displays a jam message on the control panel.
Solenoid, photosensors, and switches The following figure shows the locations of the solenoid, photosensors, and switches. 1 6 2 3 4 7 5 Figure 19. Solenoid, photosensors, and switches 1 Paper delivery sensor (PS401) senses when paper has successfully moved out of the fusing area. 2 Power switch. Note EN Products sold in North America and all of the 100-110V units do not have power switches. 3 Top-of-page sensor (PS402) detects the leading and trailing edges of the paper.
Basic sequence of operation (formatter-toprinter) The operation sequence of the printer is controlled by the microprocessor (CPU) on the ECU. The following events take place during normal printer operation: Table 14. Basic sequence of operation Period Purpose Remarks WAIT After the product is turned on until the end of the initial rotation of the main motor. To clear the drum surface of potential and to clean the primary charging roller. Detects whether or not the cartridge is installed.
Figure 20.
LIU (fax) functions and operation PSTN operation The public switched telephone network (PSTN) operates by having a central office (CO) that generates a constant voltage on the TIP and RING wires (48 V usually). When a device goes on-hook it does so by connecting impedance (such as 600 ohms for the US) across TIP and RING allowing a line current to flow. The CO can detect this current and it can send things like dial tones.
Formatter in the fax subsystem The formatter contains the modem chipset (DSP and CODEC) that controls the basic fax functions of tone generation and detection, along with channel control for the fax transmissions. The CODEC and its associated circuitry act to control transmit and receive gains, and compensate for transmission signal coupling into the receive channel. Also on the formatter is circuitry to add termination impedance to help match the telephone network impedance.
Safety-protection circuitry In addition to the safety barrier, protection against RING and overcurrent events is an LIU function. Telephone over-voltages can be either differential mode or common mode. The RING can be transient in nature (a lightning induced surge or ESD) or continuous (a crossed power line with a phone line). LIU protection circuitry provides margin against combinations of RING events.
LIU is designed so the current flows through another circuit called a gyrator or DC hold circuit. This creates the path for the central office current to flow when a call is in progress. Hook state Another magnetically coupled signal is the control signal for disconnection of the downstream telephone devices (such as a phone or answering machine). A control signal originating on the formatter can change the relay state causing the auxiliary jack (downstream jack) to be disconnected from the circuit.
Hook switch control Another signal coupled optically is the hook switch control. This is a signal from the formatter that causes an optoisolator on the LIU to go active (making an open circuit into a short circuit). When shorted, the circuit is drawing DC current from the central office and is considered “on-hook.” When open, there is no DC current and the state is considered to be “off-hook.
that the board has a linear current characteristic (normally it’s current limited). This allows more current to flow to the network as required by these special events. Billing (metering) tone filters Switzerland and Germany provide high frequency AC signals on the phone line for the purpose of billing customers. LC filters are provided on the European LIU's to prevent these billing signals from adversely affecting the data path and the DC hold circuit.
Advantages of flash memory storage Fax pages stored in flash memory are persistent. They will not be lost due to power failure no matter how long the power is off. Users can reprint faxes in case the print cartridge runs out of toner or the product has other errors while printing faxes. The HP LaserJet 3330mfp also has scan-ahead functionality that makes use of flash memory. Scan-ahead automatically scans pages into flash memory before a fax job is sent.

Checking the print cartridge Image formation defects are frequently the result of problems in the print cartridge. If there is any doubt, always replace the print cartridge before troubleshooting image defects. Use the following checklist to make sure that the print cartridge is still operable. Make sure that the print cartridge is seated properly. Inspect the print cartridge for toner level. Check the expiration date stamped on the print cartridge box.
Solving image-quality problems Use the following tables to help solve problems with printed pages. If the problem occurs when printing, see table 18, “Solving print image-quality problems,” on page 188. If the problem occurs when copying or scanning, see table 19, “Solving scanning (copying) image-quality problems,” on page 194. Also, see table 20, “Solving print paper-feed problems,” on page 197 and “Solving scanner (copier) paper-feed problems” on page 199. Solving print image-quality problems Table 18.
Table 18. Solving print image-quality problems (continued) Problem Cause Solution Toner specks appear on the printed page. . The media you are using does not meet HP’s specifications (for example, it is too moist or too rough). Make sure that the media meets specifications detailed in the Print Media Guide for the HP LaserJet family. The print path needs to be cleaned. Clean the print path. (See “Cleaning the print path” on page 59.
Table 18. Solving print image-quality problems (continued) Problem Cause Solution The printed page has a gray background. The priority input tray is not in place. Adjust the priority input tray. The print density setting is too high. Decrease the amount of background shading through the device configuration utility. The media basis weight is too high. Change the media to a lower basis weight. The humidity level is too low. Very low humidity can increase the amount of background shading.
Table 18. Solving print image-quality problems (continued) Problem Cause Solution The toner is loose, and it does not stay attached to the printed page. The inside of the printer is dirty. Clean the print path. (See “Cleaning the print path” on page 59.) The media you are using does not meet HP’s specifications (for example, it is too moist or too rough). Make sure that the media meets specifications detailed in the Print Media Guide for the HP LaserJet family.
Table 18. Solving print image-quality problems (continued) Problem Cause Solution Characters are poorly formed and are producing hollow images. The media is too slick. Try a different media. Make sure that the media meets specifications detailed in the Print Media Guide for the HP LaserJet family. The driver is not set for the correct media. 1. Select Optimize for: in the Paper tab of the driver. Select the correct media. (This affects the current print job only.) 2.
Table 18. Solving print image-quality problems (continued) Problem Cause Solution Large amounts of toner are scattered around the characters. The media resistivity is too high. 1. Use a different media. Make sure that the media meets specifications detailed in the Print Media Guide for the HP LaserJet family. 2. Turn the stack of media over and put it back in the tray. 3. Use media that is designed for laser printers. Vertical white stripes appear.
Solving scanning (copying) image-quality problems Table 19. Solving scanning (copying) image-quality problems Problem Cause Solution Pages do not print. The product is not plugged in. Make sure that the product is plugged into a live wall outlet or power strip. The computer cable is loose. Check that the cable between the product and the computer is securely connected. The tape was not removed from the print cartridge. Remove the print cartridge, remove the tape, and return the print cartridge.
Table 19. Solving scanning (copying) image-quality problems (continued) Problem Cause Solution Copies or scanned images are too light or too dark. The contrast is not set correctly. 1. Adjust the contrast and resolution settings from the control panel menu or HP LaserJet Director or HP Document Manager. 2. Check that the contrast and resolution settings are correct. See the user guide for more information. The original image is very light or very dark.
Table 19. Solving scanning (copying) image-quality problems (continued) Problem Cause Solution Scanned text is not clear. The contrast, resolution, or brightness needs to be adjusted before scanning. 1. Adjust the contrast and resolution settings from the HP LaserJet Director or HP Document Manager. 3. Check that the contrast and resolution settings are correct. See the user guide section for more information. The original is on colored paper.
Solving paper-feed problems Use the following table to solve problems related to moving paper or documents through the product. If the problem occurs when copying or scanning, see table 21, “Solving scanner paper-feed problems,” on page 199. Solving print paper-feed problems Table 20. Solving print paper-feed problems Problem Cause Solution Pages are coming out curled or wrinkled. Paper curl is inherent to the laser printing processes, and occurs when paper is subjected to heat.
Table 20. Solving print paper-feed problems (continued) Problem Cause Solution The printer feeds multiple sheets or jams frequently from the main input tray or priority input tray. Paper guides are not adjusted properly. Slide the guides against the sides of the stack in the main input tray or the priority input tray to center the paper. Make sure the guides are not adjusted too tightly. Paper was not removed from the main input tray before refilling the tray.
Solving scanner (copier) paper-feed problems Table 21. Solving scanner paper-feed problems Problem Cause Solution Long pages stop feeding through the ADF. The document is too long. The maximum document length is 381 mm (15 in). If your document is too long, copy each segment of it and scan the copies. The paper delivery sensor is damaged. Free the paper delivery sensor. If you cannot free it, replace it. Scanned items are crooked.
Functional checks Engine test The engine test is used to verify that the print engine is functioning correctly. The formatter is bypassed during an engine test, so the engine test is useful for isolating printer problems. The engine test prints horizontal lines down the entire printable area of a page and is also useful for checking and adjusting registration. Printing an engine test The engine test switch is inside the left side door, below the formatter.
Half self-test functional check The electrophotographic process can be subdivided into the following stages: image formation stage (charges the drum and writes a latent image to the drum with the laser) development stage (forms a toner image on the drum) transfer stage (transfers the image to paper) cleaning stage (removes excess toner from the drum) fusing stage (applies heat and pressure to make the image on paper permanent) To perform a half self-test check The purpose of the half sel
Drum rotation functional check The photosensitive drum, located in the print cartridge, must rotate for the print process to work. The photosensitive drum receives its drive from the main drive assembly. Note This test is especially important if refilled print cartridges have been used. 1 Open the print cartridge door. 2 Remove the print cartridge. 3 Mark the drive gear on the cartridge with a felt-tipped marker. Note the position of the mark.
Heating element check Paper passes between the heating element and a soft pressure roller to fuse toner to the paper. 1 Unplug the product for at least ten minutes. Remove the right cover (page 113) and back cover (page 130). 2 Verify that the thermistor connector is seated into both the product chassis and the ECU. 3 Unplug the fuser cable connector (callout 1) by pressing and releasing the tab on the back of the connector.
High-voltage power supply check The high-voltage power supply PCA provides the necessary voltages for the electrophotographic processes. To check the print cartridge connection points Turn the print cartridge over and visually inspect the three connection points on the ends of the print cartridge: drum ground (callout 1), charging (callout 2), and developing roller (callout 3). If they are dirty or corroded, clean the connection. If they are damaged, replace the print cartridge.
To check the high-voltage connector assembly The assembly uses three spring-loaded pins to contact the print cartridge: drum ground (callout 1), charging (callout 2), and developing roller (callout 3). Verify that the pins are not dirty or corroded and that the spring-loading action is functional. If the pins are dirty, clean them using isopropyl alcohol only. If they are damaged, replace the high-voltage connector assembly. 2 1 Figure 98. High-voltage connector assembly (right side) 2 2 3 Figure 99.
Paper path check If paper is not being picked up or is not moving through the paper path, you might want to observe all of the paper motion activities. Overriding the door interlock (SW301) allows you to observe: motor rotation solenoid action kick plate motion paper pickup roller motion drive roller, transfer roller, fuser roller and gear, and delivery roller motion To override SW301 2 1 Figure 100. Overriding SW301 1 Open the left side door and print cartridge door.
Updating or recovering the firmware code At product release, all units are manufactured with flash-memorybased formatters allowing the firmware code to be updated in the event that new firmware is released for the product or recovered in the event of code corruption or failure. When the product is mature, formatters are manufactured with permanent ROM, and updating or recovering the firmware code is not necessary.
To use the firmware recovery DIMM 1 Order a firmware recovery DIMM (RDIMM) from HP. Retain the return mailer. 2 Open the left side door and install the DIMM. 2 1 Figure 101. Using the firmware recovery DIMM 3 Plug in the product. The recovery DIMM takes a few minutes to automatically restore both blocks of firmware code. Wait until you see the message Complete in the display. 4 Unplug or turn off the product and remove the recovery DIMM. 5 Restore power to the product.
Troubleshooting tools Internal reports Use the control panel to print configuration reports and demonstration pages. The configuration report shows the settings selected from the control panel. Printing a configuration report is also considered a "self test" for the printer, although any of the reports can serve this purpose. A printout of the control panel menu structure is a useful reference if you alter settings in the menu.

Table 22. Fax receive error codes Error code Error definition Solution 200 The fax session has completed without errors. None required. 221 User has pressed cancel causing fax session to be prematurely halted. Allow the product to receive the fax. 222 The local machine has answered a call but has been unable to detect the presence of a calling fax machine. Typically this is caused by the local fax machine answering a voice call.
Table 22. Fax receive error codes (continued) Error code Error definition Solution 225 The remote machine has attempted to initiate a remote diagnostic session with this machine, even though remote diagnostic access is locally disabled. Enable the remote diagnostics capability on the local machine. 226 The remote machine has attempted to initiate a remote diagnostic session with this machine, but the remote diagnostic versions supported by the two machines are incompatible. None.
Table 22. Fax receive error codes (continued) Error code Error definition Solution 238 239 (ECM error) 240 (ECM error) 241 (ECM error) The sending fax machine sent an unexpected communication. None. This is a defect in the remote sending machine. 242 The remote fax machine is attempting to receive instead of send. Both machines have attempted to start a reception at the same time.
Table 22. Fax receive error codes (continued) Error code Error definition Solution 252 Telephone line conditions were too poor to receive a fax. 1 Reattempt the fax reception at a later time when line conditions may have improved. 2 Configure the machine to start reception at a lower speed. 3 If the local machine successfully received several pages of a larger document, ask the remote user to transmit the document in several smaller parts.
Table 22. Fax receive error codes (continued) Error code Error definition Solution 286 The remote machine has transmitted invalid data. The local machine has received frames with errors during an ECM reception and requested retransmission of the failed frames. The data that is resent does not correspond to the data that was requested. This is an implementation error from the remote machine. Disable ECM and reattempt the reception.
Table 23. Fax send error codes Error code Error condition Solution 300 Fax session has completed without errors. None required. 311 The user of the local machine has pressed the Stop key causing the session to be prematurely halted before all pages have been transmitted. None required. 312 A remote fax device has failed to answer the call. Specifically fax tones or the fax handshake from a remote machine has not been detected.
Table 23. Fax send error codes (continued) Error code Error condition Solution 319 The local machine has attempted to initiate a binary file transfer (BFT) but has detected that the remote machine does not support this mode of operation. 1 Enable the BFT capability on the remote machine if it is supported. 2 Retransmit the document as a normal fax, rather than attempting a BFT transfer.
Table 23. Fax send error codes (continued) Error code Error condition Solution 344 - 348 349-353 (ECM error) 354-355 The remote machine has failed to respond to a fax command from the local machine because the connection is interrupted. -OrThe remote user has pressed the Stop key while the reception was in progress -OrUnder rare conditions, incompatibility between the two machines may cause the remote machine to simply abandon the call.
Table 23. Fax send error codes (continued) Error code Error condition Solution 383 The remote machine has failed to respond to a fax command from the local machine because the connection is interrupted. -OrThe remote user has pressed the Stop key while the reception was in progress. Reattempt the fax transmission at a different time when telephone line conditions have improved -OrDisable ECM. 384 The local machine has attempted a black JPEG transmission to a machine that does not support this mode.
Table 23. Fax send error codes (continued) Error code Error condition Solution 390 The local machine has originated a fax session using error correction (either V.34 or V.17). Transmission of an image has been abandoned after a timeout when no data has become ready for transmission. This is most likely caused by a low-memory condition, although it could be caused by other internal problems that cause generation of data for transmission to stall.
Table 23. Fax send error codes (continued) Error code Error condition Solution 396-409 An error occurred during a V.34 transmission when the local machine was unable to correctly handshake with the remote machine and was consequently unable to transmit a T.30 frame. This occurs when the line was disconnected or if line conditions degrade during the session. Reattempt the fax transmission at a different time when telephone line conditions have improved. 410-419 Error occurred during a V.
Table 23. Fax send error codes (continued) Error code Error condition Solution 431 The transmitting machine has not received a response after aborting a transmission. Depending upon when the session is aborted, some remote machines may not respond. It should be noted that the local unit always attempts to abort the session in such a way that the remote machine is allowed to respond to the final PPS_EOP. No action required. The session was aborted. 440-444 Error occurred during a V.
