Service mode
Service mode should be used only by authorized service personnel. While in service mode, you can:
Verify and set the page count, maintenance count (pages since last maintenance), and serial number. These are shown on the configuration page.
Set the cold reset default. (This sets the factory default paper size to either Letter or A4).
Turn the diagnostic functions on or off (for developers only).
Clear the event log.
Set the page interval at which the next PERFORM PRINTER MAINTENANCE message appears on the control panel.
To use service mode
1Hold down [SELECT] and [CANCEL JOB] while turning on the printer. (If the control panel reads INITIALIZING, you released the keys too soon.)
2After the three LEDs under the display are lit, press the right side of the [MENU] key, and then press [SELECT]. The SERVICE MODE message appears. To exit the service mode press [GO].
