Service Manual
5.1 OVERVIEW
The has a sophisticated built-in self-diagnostic function that reduces troubleshooting
time by identifying failed components. This self-diagnostic test overcomes the troubleshooting
problems for page printers in which even a trivial failure can result in a serious print quality
problem.
5.2 SELF-DIAGNOSTIC FUNCTION
This section describes the self-diagnostic function in which the controller automatically checks the
operating conditions of each component. If any abnormality is detected, the printer displays an
error message on the LCD panel. Table 5-1 lists the messages that tell you when service
maintenance is required.
