Introduction
This troubleshooting chapter assumes the reader has a basic understanding of the color
laser printing process. Explanations of each mechanical assembly, printer system, and the
basic theory of operation are found in Chapter 5. Do not perform any of these
troubleshooting processes without fully understanding the function of each mechanism.
This chapter contains the following sections:
● Troubleshooting process includes a pre-troubleshooting checklist and a
troubleshooting flowchart. These tools contain information about common printer errors
that can inhibit proper operation or create print quality problems. These tools also
include recommendations for solving the cause of the error.
● Printer error troubleshooting explains each control panel display message and
suggests recommendations for clearing the cause of each message. When the printer
message indicates a failure for which the root cause is not obvious, use the printer error
troubleshooting section and the troubleshooting tools section found later in this chapter
to solve the problem.
● Paper path troubleshooting provides techniques to solve feed problems. Explanations
regarding print media checks, troubleshooting jams, and the differences between jams
caused by media and those caused by the printer are discussed.
● Image formation troubleshooting suggests methods for solving print quality problems.
● Interface troubleshooting provides techniques for isolating communication problems to
the printer hardware, printer configuration, network configuration, or software application.
● Control panel troubleshooting provides procedures for printing a menu map from the
printer control panel. It also describes the control panel menus, the items within each
menu, and the possible values for the menu items.
● Troubleshooting tools help isolate the cause of printer failures. This section includes
explanations of the printer configuration page and the event log.
● Diagnostics provides instructions on how to access and use the diagnostic tools
incorporated into the printer.
● Service menu provides procedures for entering the service menu and performing
service-oriented tasks. These tasks include counts for entering the serial number,
service ID, transfer unit maintenance, fuser maintenance, color page, total page, and
clearing the event log.
● Diagrams provides graphical locations and tables for the printer’s internal assemblies
and sensors.
