Troubleshooting process
When the printer malfunctions or encounters an unexpected situation, the printer control
panel alerts you of the situation. This section contains a pre-troubleshooting checklist to filter
out many possible causes of the problem. A troubleshooting flowchart helps you diagnose
the root cause of the problem. The remainder of this chapter provides steps for correcting
problems.
● Use the pre-troubleshooting checklist to evaluate the source of the problem and to
reduce the number of steps required to fix the problem.
● Use the troubleshooting flowchart to pinpoint the root cause of hardware malfunctions.
The flowchart guides you to the appropriate section of this chapter that provides steps
for correcting the malfunction.
Before beginning any troubleshooting procedure, check the following:
● Are supply items within their rated life?
● Does the configuration page reveal any configuration errors?
Note
The customer is responsible for checking supplies and for using supplies that are in good
condition.
