From System Off Directly to Diagnostic Mode:
When the system powers up in Diagnostic mode, the current Printhead temperature is mea-
sured. If Printhead reservoir temperature is greater than 110 degrees, thermal regulation is
restarted to keep the system warm while diagnostic tests are being run. This thermal regulation
is in addition to any test-specific initialization requirements. If possible, each test attempts to
leave the system warm. If a failure is encountered, the heaters may be turned off. If the initial
temperature is cold, thermal regulation is not started.
1. Turn the system power On and wait for the Xerox logo to begin moving across the display
2. Before the logo is centered on the display (stops moving), press and hold the Back and ?
buttons on the Control Panel.
3. Hold both buttons until the display reads "Beginning Service Mode Initialization". Release
the buttons and the system reboots into service mode with the Service Diagnostics menu
displayed.
