Status; Test Prints; Diagnostic Fault History - Xerox Phaser 6300 Service Manual

Status

Located in the General Status menu, Status reports on the condition of the printer.
Status reports either No Status to Report, or sequentially lists error conditions
occurring since power-up. Conditions that prevent printing are listed before warnings.
Status listings are not stored. If the printer reaches Ready, the list is cleared. Some
applications of status are:
Provides an initial condition from boot to begin troubleshooting.
Captures static or dynamic events.
Confirms diagnostic test results and subsequent repairs.

Test Prints

Test Prints can isolate printing problems to the Engine Control or Image Processor
Board by eliminating image data transfer between the two. Test Prints does not
exercise any Image Processor Board circuitry. Test Prints gets its image data from
ROM. This allows the examination of Engine Control Board function in isolation.
Test Prints is also useful for stimulating asynchronous (dynamic) events related to the
print process, or as a test for paper path and media related problems. Some other key
features of Test Prints:
Is the only diagnostic utility to exercise the entire print cycle.
Isolated from the operating system (PostScript). Runs from firmware.
Isolates the Image Processor Board from Engine Control Board.
Captures static or dynamic events.
Helps to isolate events that cause print artifacts or prevents printing.

Diagnostic Fault History

The Diagnostic Fault History utility records a list of engine-generated error events,
warnings are not captured, that occur during diagnostic testing. Use this utility to
record error events that occur while executing tests in Diagnostic Mode. The
Diagnostic Fault History utility captures asynchronous (transient) events only. For
static (continuous), or pre-existing events, rely on the Status utility.
