Phaser 6125/6130 Color Laser Printer Service Manual 4-5
General Troubleshooting
Service Diagnostics
The Phaser 6125/6130 printer has built-in diagnostics that allow access to
Sensors, Clutches, Solenoids, printer status, turning the motors On and Off,
and some NVRAM access. Using these tests, service technicians should be
able to diagnose the problems quickly and isolate which component or sub
assembly part needs replacement.
If confronted with an error that requires more than a cursory investigation to
clear or when directed by a troubleshooting procedure, use the diagnostic test
in Service Mode to exercise selected sub-assemblies or parts in the vicinity of
the reported error. Diagnostic tests are controlled from the Control Panel and
are described in detail in “Service Mode Diagnostic Tests” on page 4-9.
Entering Service Mode
1. Turn the printer power Off.
2. Press and hold the Up and Down Arrow buttons simultaneously and turn
the printer power On.
3. Diagnosing... message is displayed.
4. Continue to hold the buttons until the Service Mode message is
displayed on the Control Panel and release the buttons.
Using Service Diagnostics
Most of the diagnostic tests are straightforward and require no additional
explanation, but there are some that require specific conditions be met to
achieve meaningful results. These instructions cover each of the test groups,
listing special instructions, conditions, or other information necessary to
successfully interpret the results of the diagnostic tests.
