Avoiding jams

The table below lists common causes of jams and suggests solutions for resolving jams.

Table 6-2 Common causes of jams

Cause Solution

The media does not meet HPrecommended specifications.

A supply item is installed incorrectly, causing repeated jams.

You are reloading media that has already passed through a printer or copier.

A tray is loaded incorrectly.

The media is skewed.

The media is binding or sticking together.

Use only media that meets HP specifications.

Verify that all print cartridges, the transfer unit, and the fuser are correctly installed.

Do not use media that has been previously printed on or copied.

Remove any excess media from the input tray. Be sure that the stack does not exceed the maximum stack height mark in the input tray.

The tray guides are not adjusted correctly. Adjust the guides so they hold the stack firmly in place without bending it.

Remove the stack and flex it, rotate it 180°, or flip it over. Reload the stack into the tray.

NOTE: Do not fan paper. Fanning can create static electricity which can cause paper to stick together.

The media is removed before it settles into the output bin.

When duplexing, the paper is removed before the second side of the document is printed.

Reset the printer. Wait until the page completely settles in the output bin before removing it.

Reset the printer and print the document again. Wait until the page completely settles in the output bin before removing it.

The media is in poor condition.

The internal rollers do not pick up media from tray 2 or tray 3.

Replace the media.

Remove the top sheet of media. If it is heavier than

163 g/m 2 (43 lb), it might not be picked from the tray.

Replace the media.

The media has rough or jagged edges.

The media is perforated or embossed.

The supplies have reached the end of their useful life.

This type of media does not separate easily. You might need to feed single sheets from the multipurpose tray.

Check the printer control panel for messages prompting you to replace supplies, or print a supplies status page to verify the remaining life of the supplies.

The media was not stored correctly. Replace the media. Media should be stored in the original packaging in a controlled environment.

Image-formation troubleshooting

This section identifies issues that can affect print quality. For additional information, see the

HP LaserJet Printer Family Print Media Guide.

Print-quality problems associated with media

Some print-quality problems arise from use of inappropriate print media.

● Use media that meets HP paper specifications.

● The gloss and transparency films are very smooth. Use paper that meets HP paper specifications.

● The driver setting is incorrect. To change the paper-type setting, see Type and Size.

● The media you are using is too heavy for the paper-type setting you selected, and the toner is not fusing to the paper.

212 Chapter 6 Troubleshooting ENWW

● The moisture content of the paper is uneven, too high, or too low. Use paper from a different source, from an unopened ream of paper, or dry out the paper (100˚C [212˚F] for 24 hours).

● Some areas of the paper reject toner. Use paper from a different source or from an unopened ream of paper.

● The letterhead you are using is printed on rough paper. Use a smoother, xerographic paper. If this solves your problem, consult with the supplier of your letterhead to verify that the paper used meets the specifications for this printer.

● The paper is excessively rough. Use a smoother, xerographic paper.

● Avoid media containing metallic laminates or conductive surfaces.

Defects on overhead transparencies

Overhead transparencies can show the image-quality problems as any other type of media, as well as defects that are specific to printing on transparencies. Because transparencies are pliable while in the print path, the paper-handling components can also mark them.

NOTE: Allow transparencies to cool for at least 30 seconds before handling them.

● Change the pre-rotation setting in CONFIGURE DEVICE/PRINT QUALITY/OPTIMIZE/PRE-

ROTATION=ON. This enhances transparency print quality by raising the fuser pressure roller temperature to more closely match the sleeve temperature.

● Change the transparency mode in CONFIGURE DEVICE/PRINT QUALITY/PRINT MODES/

TRANSPARENCY to B TRNSPRNCY (Best Transparency) mode. This optimizes transparency print quality and minimizes transparency curl.

NOTE: If the printer media sensor rejects a supported color laserjet transparency, make sure that the transparency is not from an old box. Try a new box.

● In the printer driver Paper tab, select Transparency as the paper type. Also, make sure that the tray is correctly configured for transparencies.

● Check that the transparencies meet the specifications for this printer. For more information about media specifications and for ordering information, consult the HP LaserJet Printer Family

Print Media Specification Guide.

● If print-quality defects occur, then make sure that the transparencies are designed for correct toner adhesion. Use only transparencies that are designed for HP Color LaserJet printers.

● Handle transparencies by the edges. Oil from fingers can cause spots and smudges on the transparencies.

● Small, random, dark areas on the trailing edge of solid fill pages might be caused by transparencies sticking together in the output bin. Try printing the job in smaller batches.

● If the selected colors are not what you want when printed, then select different colors in the program or printer driver.

● If you are using a reflective overhead projector, then use a standard overhead projector instead.

ENWW Jams 213

Print-quality problems that are related to the environment

If the printer is operating in excessively humid or dry conditions, verify that the printing environment is within specifications. See the getting started guide for this printer for information about operatingenvironment specifications.

Print-quality problems that are related to jams

Make sure that all media is cleared from the paper path.

● If the printer recently jammed, print two to three pages to clean the printer.

● If the media does not pass through the fuser, image defects appear on subsequent documents.

Print two to three pages to clean the printer.

Print-quality problems from toner buildup

Over time, toner and other particles can build up inside the printer. This buildup can cause the following print-quality problems:

● Marks at even intervals on the printed side of the page

● Toner that smears easily

● Toner specks on the page

● Vertical streaks or bands on the page

To correct these types of problems, clean the printer. See Cleaning the printer on page 38

224 Chapter 6 Troubleshooting ENWW

Repetitive-defects troubleshooting

Defects on printer rollers can cause image defects to appear at regular intervals on the page. Use

Table 6-26 Causes of repetitive defects on page 225

to determine which roller is causing the defect.

To resolve the problem, try cleaning the roller. If the roller remains dirty after cleaning or if it is damaged, replace it.

Repetitive defects for the transfer unit normally appear on every other page, because the transfer belt is longer than a page. However, the period of the repetitive defect can vary depending on the type of media, and a repetitive defect can occur more than once on the same page.

CAUTION: Do not use solvents or oils to clean rollers. Instead, use lint-free paper to clean the roller. If dirt is difficult to remove, dampen the paper with rubbing alcohol.

NOTE: Defects on the tray 2 pickup roller or the multipurpose-tray pickup roller do not cause a repetitive defect, but instead cause a defect on the leading edge of the page.

Interface troubleshooting

Communication checks

NOTE: Communication problems are normally the customer’s responsibility. Time spent attempting to resolve these problems might not be covered by the Hewlett-Packard warranty.

Refer the customer to the network administrator for assistance in troubleshooting network problems.

If the printer is not connected to an MS-DOS-based host, use the following table to check the connection.

Table 6-27 Communication check

Check Action

Does the computer configuration match the parameters described in the configuration instructions?

Verify that the configuration of the computer's communications port matches these parameters. View the Jetdirect configuration page for print server status, and to verify configuration parameters for operation on your network.

NOTE: If these parameters are not set correctly, an error message might appear on the control panel.

EIO troubleshooting

If the printer contains an optional HP Jetdirect print server and you cannot communicate with the printer over the network, verify the operation of the print server. Print a configuration page. If the

Jetdirect card does not appear under “Installed personalities and options” on the configuration page, see the troubleshooting section of the HP Jetdirect Print Server Administrators Guide supplied with the print server.

If the host system and printer still do not communicate, replace the formatter PCB or the EIO card and reconfigure the printer. If the problem persists, use a protocol analyzer to find the source of the problem.

CAUTION: HP LaserJet printers are not designed to work with mechanical switch-box products that do not have surge protection. These devices generate high transient voltages that cause permanent damage to the formatter PCB. This circumstance is not covered under the Hewlett-Packard warranty.

Diagnostics

The following section describes the printer's diagnostics.

LED diagnostics

Use the following procedure to help identify the cause of high-level printer problems. These problems are indicated by abnormalities in the printer's power-on sequence. The LED that the procedure refers to is on the formatter. This is the “heartbeat” LED that blinks on and off when the formatter is operating correctly.

Does the LED blink with four fast bursts at power on? If not, then perform the following checks:

● Check the firmware.

● Check the memory.

● Check the formatter.

Does the LED blink at a fast, steady rate during memory testing (one blink per 8 MB)? If not, then perform the following checks:

● Check the control-panel display for an error code.

● Check the memory.

● Check the formatter.

Is the LED off for about eight seconds, while the boot code is decompressing, before the display turns on? If not, then perform the following checks:

● Check the firmware.

● Check the control-panel display for correct connections and operation.

● Check the control-panel display for an error code.

Does the LED blink at a steady rate of one blink per second? If not, then perform the following checks:

● Check the firmware.

● Check the formatter.

● Check the control-panel display for an error code.

If the control-panel display does not illuminate, perform an engine test to check the engine. You must have media loaded in tray 2 for the engine test.

Diagnostics mode

Some of the diagnostics tests automatically put the printer into a special diagnostics mode. During the special diagnostics mode the printer performs actions that normally cause the printer to enter an error state. Always follow the control panel directions in the DIAGNOSTICS menu to exit the special diagnostics mode correctly and return the printer to a normal state.

230 Chapter 6 Troubleshooting ENWW

Diagnostics that put the engine into the special diagnostics mode

Four diagnostics tests put the engine into a special state:

● Disable cartridge check

● Sensor test

● Manual sensor test

● Component test

While the printer is in the special diagnostics mode, the following message should appear:

READY DIAGNOSTICS MODE

TO EXIT PRESS STOP KEY

When the printer is in the special diagnostics mode, these four tests appear in the menu and are available to be run. To gain access into other diagnostic tests or to leave the special state, press

Stop , and then select Exit. The printer resets itself, and then returns to the normal state.

NOTE: You need to have a good understanding of how the printer operates in order to use the engine diagnostics successfully. Before proceeding with these diagnostic tests, make sure that you understand the information in chapter 4 of this manual.

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 printer with the covers removed, the door switch lever

(SW1, callout 1) must be depressed (this is the door-closed position).

WARNING!

Be careful when performing printer diagnostics to avoid the risk of injury. Only trained service personnel should open and run the diagnostics with the covers removed.

Never touch any of the power supplies when the printer is turned on.

ENWW Diagnostics 235

NOTE: The door interlock switch must be defeated to run any of the component tests. If covers are removed, the door switch must be manually cycled during some tests in order for the engine to recognize a change. The ETB assembly can be open, closed, or removed while some of these tests are executing. Print cartridges can be installed or removed during certain tests.

Select the component test options when the printer prompts you.

Menus cannot be opened during component tests, so serves the same function as the Stop button.

You can perform the following component tests:

● Transfer motors. This test turns the components that are involved in the image-transfer process: the cartridge motors, the ETB motor and belt, and the print cartridges (if the ETB is closed). You can remove or install print cartridges during this test.

● Belt only. This test turns only the ETB motor and belt. The control-panel display prompts you to remove the cartridges because the ETB belt contacts the photosensitive drums and cannot turn without them also rotating the drums. Rotating the photosensitive drums can damage the belt or photosensitive drums. If covers are removed, you must manually activate the door switch after removing the cartridges in order to run the test.

● Cartridge motors. This test rotates only the print-cartridge drive motors. The control-panel display prompts you to remove at least one cartridge because the ETB belt contacts the photosensitive drums and cannot turn without also rotating the drums. The engine rotates the cartridge motor(s) for only the cartridges that are removed. To rotate all motors sequentially, remove all of the cartridges; to isolate one motor, remove only that cartridge. If covers are removed, you must manually activate the door switch after removing the cartridges in order to perform the test. Always start this test with all of the cartridges installed, and activate the door switch so that the printer recognizes the configuration. Then you can proceed with the test by removing one or more cartridges.

● Black, Magenta, Yellow, Cyan laser/scanners. Use these tests to rotate each scanner motor individually.

● Fuser motor. Use this test to rotate the fuser motor and drive gears.

● Fuser pressure release motor. Use this test to rotate the fuser pressure-release motor.

● Alienation motor (also called the developing disengaging motor). This test moves the developing disengaging motor, clutches and gears, and plates through their positions.

● ETB contact/alienation. This test activates the ETB motors and solenoid.

● Tray 1 pickup solenoid. This test activates and releases the multipurpose tray (tray 1) pickup solenoid.

● Tray 2 pickup motor. This test activates and moves the tray 2 pickup motor and gear train.

236 Chapter 6 Troubleshooting ENWW

● Tray 2 pickup solenoid. This test activates and releases the tray 2 pickup solenoid.

● Tray 3 pickup motors and solenoids. These tests run the same way as the tray 2 pickup motor and solenoid test.

NOTE: You must have the tray partially installed or must manually lift the pickup roller assembly/lifter plate.

● Duplexer pickup motor. This test activates and moves the duplexer pickup motor.

Print/Stop test

Use this diagnostic test to isolate the cause of problems such as image-formation defects and jams in the engine. During this test you can stop the paper anywhere along the printer paper path. The test can be programmed to stop printing internal pages or an external print job when the paper reaches a certain position. The test can also be programmed to stop from 0 to 60,000 mS. If the timer is set to a value that is greater than the job print time, you can recover the printer the following ways:

● After the print job is complete, press Stop to return to the DIAGNOSTICS menu before the timer times out.

● After the timer times out, press Stop . Activate the door switch to restart the engine and return it to a normal state.

When the timer trips, the message Printing stopped Press to continue appears on the controlpanel display. Press Menu to print the previously selected job. If you do not want the previous job to print, press Stop and then press Menu .

NOTE: Do not attempt to perform a Print/Stop test while the printer is calibrating because you will be required to turn the printer off and then on again. If a jam message appears on the control-panel display during testing, activate the door switch.

Drum-rotation test

The photosensitive drum, located in the print cartridge, must rotate in order for the print process to work. The photosensitive drum receives its drive from the main motor through a system of gears on the right side of the printer.

NOTE: This test is especially important if refilled print cartridges have been used.

Open the front door.

Remove the print cartridges.

Mark the drive gear on the cartridge with a felt-tipped marker. Make note of the position of the mark.

Install the print cartridges and close the front door. The startup sequence should rotate the drum enough to move the mark.

Open the front door and inspect the gear that was marked in step 3. Verify that the mark moved.

If the mark did not move, inspect the drive shaft that moves into the print-cartridge area when the front door is closed to make sure that it is meshing with the print cartridge. If the drive shaft looks functional and the drum does not move, then replace the print cartridge. If the drive shaft is damaged, then replace the printer.

Service ID

When printing from an HP Color LaserJet 3000/3600/3800/CP3505 Series printer, this information appears on the configuration page, which eliminates the need for customers to keep paper receipts for proof of the warranty. Because the printer has an internal clock, the availability of the service ID date depends on the printer being connected to a source that can provide the date, in this case a time server that is on the same network as the printer. When the printer is not connected to a date source, the service ID is not available, and 00000 appears on the configuration page.

Converting the Service ID to an actual date

You can use the printer Service ID number to determine whether the printer is still under warranty.

Use the following procedure to convert the Service ID into the installation date.

Add 1990 to YY to determine the actual year that the printer was installed.

Divide DDD by 30 (and, if there is a remainder, add 1 to the quotient) to determine the month the printer was installed.

The remainder from the calculation in step 2 is the day of the month. If no remainder resulted from the calculation in step 2, then the day of the month is the 30th.

Using the Service ID 12287 as an example, the date conversion is as follows:

12 + 1990 = 2002, so the year is 2002.

287 divided by 30 = 9 with a remainder of 17. Add 1 to 9 to get 10, so the month is October.

The remainder (from the above calculation) is 17, so that is the day of the month.

The complete date is 17-October-2002.

A 6-day grace period is built into the date system.

Restoring the Service ID

If you replace the formatter, the Service ID is lost and must be restored. Use this menu item to reset the Service ID, which is calculated based on the date the printer was first used. The date format is

YYDDD. Use the following procedure to calculate the Service ID.

To calculate YY, subtract 1990 from the calendar year.

To calculate DDD, use the following formula: 30 * (calendar month – 1) + calendar day = DDD.

(If the calendar day is 31, use 30 instead.)

Using October 17, 2002, as the date the printer was first used, the service ID conversion is as follows: a.

2002 minus 1990 = 12, so YY = 12.

10 minus 1 (calendar month minus 1) = 9.

9 times 30 = 270.

270 plus 17 (the calendar day) = 287, so DDD = 287.

The complete service ID number is 12287.

How to use the parts lists and diagrams

The figures in this chapter show the major subassemblies in the printer and their component parts. A parts list table follows each exploded-view assembly diagram. Each table lists the item number, the associated part number, and the description of each part. If a part is not listed in the table, then it is not a field replacement unit (FRU).

CAUTION: Be sure to order the correct part. When looking for part numbers for electrical components, pay careful attention to the voltage that is listed in the description column to ensure that the part number selected is for the correct printer model.

NOTE: In this manual, the abbreviation “PCA” stands for “printed circuit board assembly.” components described as a PCA might consist of a single circuit board or a circuit board plus other parts, such as cables and sensors.

Safety statements

Laser safety

The Center for Devices and Radiological Health (CDRH) of the U.S. Food and Drug Administration has implemented regulations for laser products manufactured since August 1,1976. Compliance is mandatory for products marketed in the United States. The printer is certified as a Class 1 laser product under the U.S. Department of Health and Human Services (DHHS) Radiation Performance

Standard according to the Radiation Control for Health and Safety Act of 1968. Since radiation emitted inside the printer is completely confined within protective housings and external covers, the laser beam cannot escape during any phase of normal user operation.

WARNING!

Using controls, making adjustments, or performing procedures other than those specified in this user guide may result in exposure to hazardous radiation.
