4-4
The Phaser 6128MFP printer has built-in diagnostics to test Sensors, Clutches,
Solenoids, display printer status, and provides some NVRAM access. Use these
tests to diagnose problems 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 tests 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 Diagnostic Tests" on page 4-9.
1. Turn the printer power Off.
2. Press and hold the Up and Down Arrow buttons simultaneously and turn the
printer power On.
3. Release the Arrow buttons when Please Wait... message is displayed.
4. The Service Mode menu appears with FAX/Scanner Diag and Printer Diag
and test groups listed to indicate the printer is in service mode.
Two test groups, FAX/Scanner Diag and Printer Diag are avilable to test
components of the ADF, Scanner, Fax, or printer. 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.
Diagnostic tests are arranged in a menu structure. Use the Arrow buttons to scroll
through the menus and highlight the desired test. The OK button runs the test. To
switch between test groups, exit the current diagnostics mode and return to the
Service Mode menu.
