Service mode overview Service mode allows service personnel to verify and manipulate internal printer settings and to access the diagnostic feature. Service mode should be used only by authorized service personnel. You can perform the following tasks while in Service mode: • Print a Service mode self-test. • Verify the page count. • Set the page count. • Set the maintenance count. • Set the maintenance interval. • Verify and set the serial number. • Set the cold reset default.
LJ 1200 Service mode functions Initializing NVRAM and using cold reset The NVRAM initialization sets all default variables stored in NVRAM back to the factory default values or to a default ROM value, depending on the variable. It also performs a system reset. The NVRAM initialization resets the following: • All menu settings to factory default values • Factory settings, such as formatter number, page counts, and factory paper settings To perform NVRAM initialization 1 Turn the printer off.
PJL software commands To set the following NVRAM variables: Factory printer DEFAULT PAPER and copier/scanner factory default paper size are set to the same value automatically. Factory printer DEFAULT LPARM:PCL SYMSET Factory DEFAULT OEM bit Factory DEFAULT PRINTPAGECOUNT 2 Factory DEFAULT SCANPAGECOUNT Factory DEFAULT COPYPAGECOUNT Default Quick Copy paper size is also stored in the scanner NVRAM, but is changed only through the software or when set back to factory default with a NVRAMINIT.
The table below provides a more detailed description of the NVRAM PJL factory variables and commands and shows possible settings for each.
NVRAM PJL factory variables To use the following commands, you need some method to send PJL commands to the printer, either with a software tool or by copying a binary file that contains the commands from the host using an MS-DOS® box.
LJ 2200 Service mode functions In Service mode, the following can be performed: • Print a Service mode self-test. • Verify and set the page count. • Set the cold reset default. • Set the demo page = true/false. • Set the diagnostic functions on or off. Entering Service mode Use PJL commands to enter Service mode and perform various Service mode configurations. Users must use the exact character and case specified for PCL printer commands.
Entering escape characters Printer commands always begin with the escape character (ESC). The following table shows how the escape character can be entered from various MS-DOS programs.
Setting the page count The page count is stored in the printer’s NVRAM. If it is necessary to replace the formatter PCB, the page count should be reset to the printer’s original page count to reflect the age of the print engine. Before removing the old formatter PCB, print a self-test/configuration page to verify the current page count of the printer.
Setting the cold-reset default The customization variable will determine the default paper size after a cold reset. This is set to A4/letter at the manufacturer. This variable might need to be reset when the formatter is replaced.

AC and DC power distribution HP LaserJet 1200 Series printer 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. The 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.
Overcurrent/overvoltage There are two overvoltage devices in this printer: • Fuse F101 provides overcurrent protection for the fusing system circuitry. Checking or replacing the fuse requires the removal of the ECU. Fuse F102 provides overcurrent protection to the printer DC power-supply circuitry. • In addition, the +24 VDC and +3.
HP LaserJet 2200 Series printer • The power switch supplies AC power to the low-voltage powersupply circuit when it is turned on. This circuit supplies DC voltage (+24 V, +5 V, +3.3 V) to the main motor, laser/scanner unit, interlock switch, formatter, solenoids, paper feeder, high-voltage power supply, and formatter. • The DC voltage supplied to the high-voltage power-supply circuit is interrupted when the top cover is open.

HP LaserJet 4100 Series printer AC/DC power distribution In this circuit, the AC power input from the power receptacle is converted into DC power. The DC power is supplied to the loads. The AC power is supplied to the low-voltage power-supply circuit in the engine controller board when the power switch (SW1) is turned on. The AC power is converted into +24 VDC, +5 VDC, and +3.3 VDC in the circuit.
Figure 4 138 Low-voltage power-supply circuit (LJ 4100 series) Chapter 3 – Power supply EN
Overcurrent/overvoltage protection If a short-circuit or other problem on the load side causes an excessive current flow or generates abnormal voltage, the overcurrent/ overvoltage protection systems automatically cut off the output voltage to protect the power-supply circuit. If the overcurrent or overvoltage protection system are activated and the power-supply circuit does not generate DC voltage, it is necessary to turn the power off, correct the problem, and then turn the printer on again.
Protection systems Problems on the load side, such as short circuits, can cause an excessive flow of current from the DC power supplies or can generate abnormal voltage. When this happens, the excess-current and excess-voltage protection systems automatically shut off the output voltage to protect the power supplies.

Bidirectional interfaces The formatter receives incoming data through its bidirectional interface (IEEE 1284) or USB interface. The parallel interface or USB interface both provide high-speed, two-way communication between the printer and the host, letting the user change printer settings and monitor printer status from the host computer. Note LJ 4100 only: The user can configure the HIGH SPEED item in the Control Panel menu.
Attaching the parallel cables The printer’s parallel port can have one or both of the following connectors: • B-type parallel (large) • C-type parallel (small) B-type C-type Figure 5 Printer-interface connections 4 EN Bidirectional interfaces 143
Network interfaces LocalTalk I/O The printer implements AppleTalk networking protocol through LocalTalk hardware. The LocalTalk network cable is connected through the EIO card. Note This feature applies to the LJ 2200 and LJ 4100 only. Expanded I/O The optional expanded I/O card can be installed in the slots provided on the formatter PCA. The expanded I/O card provides automatic I/O switching between multiple computers or networks connected to the printer.
IR interface The FIR port is located on the lower right corner of the 2200 printer or is available as an accessory on the 4100 printer. This port is compliant with the specifications determined by the IrDA. On the right side of the FIR port is a status light that indicates when the port is active. The FIR port transmits data at speeds of up to 4 MB per second. When the infrared (IR) connection is established, the FIR status light comes on.

Troubleshooting media problems Paper problems can be difficult to detect. The following series of steps will help isolate media-induced problems versus printer problems: • Isolate a paper path. • Isolate a brand of media. • Isolate a type of media. • Evaluate media-use practices. • Evaluate environmental conditions. Here are some media usage tips: • Turn the media over and print on the other side. Doing so often corrects excess paper curl.
General tips Paper curl Paper curl results from both the heating process used to bond the print image (toner) to the media and from the path that the media must negotiate through the printer. Take the following actions to help reduce paper curl: 1 Turn the media over in the input tray. Some media packages (reams) have an arrow indicating the preferred printing side. Experiment to determine which orientation yields the least curl. 2 Try a different output paper path (if available for your printer).

Preventing jams caused by labels As with envelopes, prevention is the best way to avoid printer malfunctions caused by adhesive labels. To prevent jams and feed problems, labels must meet the following requirements: • Be cut long grain (as opposed to short grain). • Totally cover the carrier sheet (no spaces between labels, no removed labels). • Contain no excessive glue. (The adhesive should be acrylic-based emulsion and should not come into direct contact with the printer.

Potential toner cartridge issues Banding When printing with a laser printer, the toner is applied across the page in horizontal strips. The page is moved through the printer and toner is continually applied. When printing text or black image pages, a large amount of toner is deposited on the page. As the amount of toner deposited on the page decreases, slight speed variations become more apparent.
Toner cracking When the media is folded and the crease aligns with a line of text, it is possible with certain types of media for the text to break along the line, giving the appearance of a white line through the text. Media that does not meet the smoothness (100 to 250 Sheffield, 100 to 500 Bendtsen) or wax pick (>11 Dennison) is likely to exhibit this effect more than other media. Toner in the HP LaserJet printers is composed of minute particles of pigmented plastic material (styrene) and iron oxide.
Transfer of toner image After printing a document on an HP LaserJet printer, folding it, and sending it through the mail, you might observe that a portion of the print image was transferred to opposing surfaces of the folded document. The laser printing process uses a pigmented, plastic powder (toner) to form a print image that is first transferred to a sheet of paper (or other print medium) and then melted (fused) onto the surface of the paper to form a permanent image.
Transfer of toner image (continued) Because of the way that laser printing is accomplished, currently there is no way to entirely eliminate the possibility of toner transfer. However, using these techniques should yield more satisfactory results and will often reduce the problem to imperceptible levels. Gray background on envelopes Poor print quality is normally the result of using envelopes that are of the incorrect weight or finish.
Recycling toner cartridges In many countries, HP toner cartridges can be returned to HP through the HP Printing Supplies Environmental Program. An easy-to-use takeback component of the program is available in more than 20 countries. Multilingual program information and instructions are included in every new HP LaserJet toner cartridge and consumables box. For more information: call (1) (800) 340-2445 (U.S. only) or visit the HP LaserJet supplies website: U.S.: http://www.hp.com/ljsupplies/environment_main.
Refilled toner cartridges HP policy on non-HP toner cartridges Hewlett-Packard Company cannot recommend use of new, refilled, or remanufactured, non-HP toner cartridges. Because they are not HP products, HP cannot influence their design or control their quality.
Toner safety Handling and storage WARNING! Keep toner cartridges and toner particles away from excessive heat, sparks, and open flames. If toner is spilled, avoid breathing in toner particles. Inhalation of toner particles can cause respiratory tract irritation. Vacuum or sweep the material into a bag or other sealed container. If a vacuum is used, the motor must be rated as dust-tight. Dispose of waste toner in accordance with local requirements. Do not discharge toner particles in drains.

Cleaning page For print-quality defects, try generating a cleaning page from the printer control panel (LJ 1200, 2200, 3200, 4100) or from the JetSuite Pro software (LJ 3100 and 3150). For the cleaning page to work properly, make sure to print the page on a transparency or copier-grade paper (not bond or rough paper), depending on the printer model.
LJ 1200 series Note This process requires use of a transparency to remove dust and toner from the print paper path. If transparency film is unavailable, you can use copier-grade paper. If you must use paper, perform the procedure two or three times to ensure proper cleaning. 1 Load a transparency in the priority input tray. 2 Make sure that the printer is in the Ready state. 3 Press and hold the Go button for 10 seconds. The transparency feeds through the printer slowly. Discard the transparency.
LJ 2200 series Note This process requires use of a transparency to remove dust and toner from the print paper path. If transparency film is unavailable, you can use copier-grade paper. 1 Make sure the printer is turned on and in the Ready state. Load a transparency in tray 1. 2 Press Go and hold for 10 seconds. 3 Release Go, the lights will cycle from front to back until the cleaning process has completed.
LJ 3100 and 3150 series 1 Place a stack of plain letter- or A4-sized paper into the paper-input bin. (Do not use thick or rough paper.) 2 For Microsoft Windows 95 or Windows 98, open Windows Explorer. OR For Windows 3.1x, open File Manager. 3 Open the JetSuite folder (if the JetSuite Pro software was installed to the default location, the path is “C:\JetSuite”). Note If you do not have access to JetSuite Pro software, a cleaning page is available from the HP web addresses: http://www.hp.
LJ 3200 series Note This process requires copier-grade paper to remove dust and toner from the print paper path. Do not use bond or rough paper. 1 Place the copier-grade paper into the document-feeder tray. 2 Ensure that the product is in the Ready state, and then press Enter/Menu. 3 Use < or > to select SERVICE, and then press Enter/Menu. 4 Use < or > to select CLEANING MODE, and then press Enter/ Menu. 5 Press Enter/Menu to start the cleaning mode.
LJ 4100 series This process requires copier-grade paper to remove dust and toner from the print paper path. Do not use bond or rough paper. Creating a cleaning page From the printer control panel, do the following: 1 Press Menu until PRINT QUALITY MENU appears. 2 Press Item until CREATE CLEANING PAGE appears. 3 Press Select to create the cleaning page. 4 Follow the instructions on the cleaning page to complete the cleaning process. You might need to create and process a cleaning page more than once.
LJ 4100 series (continued) Using the auto-cleaning page The auto-cleaning page feature helps keep the fuser rollers clean, which maintains excellent output quality. The auto-cleaning page feature is accessible through the control panel and is supported through Web JetAdmin, as well. Once set up, the printer runs a cleaning page through the printer as a separate job at the frequency requested with no further user intervention. The settings can be changed or the feature can be turned off at any time.
