Q2431-90912 Chapter 7 Troubleshooting 231

Troubleshooting process

When the printer malfunctions or encounters an unexpected situation, information on the printer

control panel alerts you to the situation. This section contains an initial troubleshooting checklist

that helps to eliminate many possible causes of the problem. The subsequent troubleshooting

flowchart helps you to diagnose the cause of the problem. The remainder of the chapter provides

steps for correcting the problems that have been identified.

● Use the initial troubleshooting checklist to evaluate the source of the problem and to

reduce the number of steps that are required to fix the problem.

● Use the troubleshooting flowchart to pinpoint the cause of malfunctions. The

flowchart lists the section within this chapter that provides steps for correcting the

malfunction.

Before beginning any troubleshooting procedure, check the following:

● Are supply items (for example, the print cartridge, fuser, and rollers) within their

rated life?

● Does the configuration page reveal any configuration problems? See “Configuration

page” on page 241.

Hint The customer is responsible for checking and maintaining supplies, and for using supplies that

are in good condition. The customer is responsible for media and print-cartridge supplies. The

customer is also responsible for replacing the fuser, transfer roller, and all paper pickup, feed, and

separation rollers (tray 1 has a separation pad instead of a roller) that are at or near the end of

their 200,000-page rated life.
