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
