6. Troubleshooting
Start
• Unplug power from the machine before connecting or disconnecting any cable, assembly, or
electronic card. This is a precaution for personal safety and to prevent damage to the machine.
Use the service error code, user status message, user error message, symptom table, service checks,
and diagnostic aids in this chapter to determine the corrective action necessary to repair a
malfunctioning machine. They will lead you to solutions or service checks, including use of various tests.
Symptom Tables
If your machine completes the “Power–On Self Test (POST) sequence” in the “Troubleshooting” without
an error and you have a symptom, then go to “Service error codes” in the “Troubleshooting”. Locate
your symptom, and take the appropriate action.
Service Errors (8xx.xx / 9xx.xx’s)
If a service error code appears while you are working on the machine, then go to “Service error codes”
in the “Troubleshooting”, and take the indicated action for that error.
Service error codes are indicated by a three-digit error code followed by a period and additional
numbers in the format XXX.YY. In most cases, five digits are shown.
User Status and Attendance Messages
• User status messages provide the user with information on the current status of the machine. Ready
displays on the first line of the display unless invoked, and then Power Saver displays. If a user
status message is displayed, then go to “Service error codes” in the “Troubleshooting”.
• User attendance messages are indicated by a two- or three-digit error code that provides the user
with information that explains a problem with a print cartridge, paper jam, option, port, and so on.
If a user error message displays, then go to “User attendance messages” in the “Troubleshooting”
and “Paper jam error codes (200-series)” in the “Troubleshooting”.
