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.
