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 in this chapter 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 2-2.

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 2-6.

If your machine does not have a service error code and does not complete POST, go to the “POST Symptom Table” on page 2-10. If your machine completes POST without an error, and you have a symptom, go to the “Base Printer Symptom Table” on page 2-10. 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 2-2 and take the indicated action for that error.
