Diagnostics

Start

CAUTION:

NEVER

manually actuate or disable the top cover

interlock switch and the printhead shutter actuator at the same

time

. To perform some of the service checks and tests, such as

troubleshooting paper feed problems, you need to actuate the top cover

interlock switch with the covers opened or removed and power applied

to the machine. It is important for personal safety that you

DO NOT,

FOR ANY REASON

, disable the printhead shutter actuator when power

is on.

Remove power from the printer before you connect or disconnect any

cable or electronic board or assembly for personal safety and to prevent

damage to the printer.

Use the service error code, user error message, symptom table, service

checks, and diagnostic aids to determine the corrective action

necessary to repair a malfunctioning printer.

The lights on the operator panel can indicate either a user error

message or service error message. When a service error occurs the

printer stops printing and all operator panel LEDs blink in a continuous

pattern, indicating a service error, until the printer is powered off. If all

operator panel LEDs are blinking, go to the “Service Error Codes” on

page 1-5.

When a user error message occurs, one or two operator panel LEDs

are on solid or blinking. Go to the “User Error Message Table” on

page 1-8.

If your machine does not have a service error code and does not

complete POST, go to the “POST Symptom Table” on page 1-11. If your

machine completes POST without an error, and you have a symptom,

go to the “Symptom Table” on page 1-12. Locate your symptom and

take the appropriate action.

If a service error code appears while you are working on the machine,

go to the “Service Error Codes” on page 1-5 and take the indicated

action for that error.

If your printer did not successfully complete POST, locate the symptom

in the “POST Symptom Table” on page 1-11 and take the appropriate

action.

1-4

Laser Printer Reference Handbook

4026-0XX

If the printer completes all these steps and no error indications are

displayed, the printer has successfully completed the POST. If the

printer has completed POST without an error and a symptom exists, go

to the “Symptom Table” on page 1-12.

Power-On Self Test (Post)

The printer performs the following Power-On Self Test when powered

on:

1. All LEDs come on solid.

2. The fan turns on for 2 seconds.

3. All the LEDs turn off.

4. The engine board checks the status of the cover interlock switch.

5. The LEDs begin to turn on then off continuously.

6. The fan turns off.

7. The engine board checks the status of the paper exit sensor.

8. The engine board checks the status of the thermistor.

9. The fuser lamp turns on.

The printer may be idle for up to 40 seconds as the fuser warms

to operating temperature. Printer idle time is shorter if the fuser is

already warm.

10. The polygon motor (printhead motor) turns on.

11. The main motor turns on.

12. The paper feed gears turn.

13. The print cartridge drive gear engages.

14. The paper feed take-up shaft and D-roll assembly rotates to

home position. (The paper feed lift plate assembly is in the down

position).

15. All the LEDs turn off.

16. Model 4026-06A, 06D - The Ready LED turns on solid and the

Data LED blinks. Go to Step 17.

Model 4026-06B, 06E - The Ready LED turns on solid and the

Data LED blinks.

• The controller board checks flash ROM installation.

• The controller board verifies that flash is formatted.

• The controller board attempts to format flash if unformatted.

• The Data LED blinks during format.

• The printer continues POST after format is complete.

• If format fails, a “Flash Memory Failure” error displays.

4026-0XX

17. The main drive motor turns off.

18. The polygon motor (printhead motor) turns off.

19. The Data LED turns off.

20. The Ready LED stays on solid.

If the printer completes all these steps and no error indications are

displayed, the printer has successfully completed the POST.

Service Error Codes

When a service error occurs the printer stops printing and all operator

panel LEDs blink in a continuous pattern, indicating a service error, until

the printer is powered off.

Press and release the operator panel button to display the service error

code. Locate the blinking LEDs in the following table and take the

indicated action.

Blinking Operator Panel LED Action

Software Service Error Code Run the Printer Diagnostic Test to

diagnose between the ROM SIMM

and the controller board. If no other

error code displays after the test

completes, replace the controller

board.
