Diagnostics menu
The diagnostics menu allows you or a service representative to run tests that can help
identify and solve problems with the printer.
Menu item Description
PRINT EVENT LOG This item will print an event log that will display
the last 50 entries in the printer event log, starting
with the most recent.
SHOW EVENT LOG This item displays the last 50 events on the
control panel display, starting with the most
recent.
PQ TROUBLESHOOTING This item will print a series of print quality
assessment pages that will help troubleshoot
many print quality problems.
DISABLE CARTRIDGE CHECK This test allows you to print with one or more
cartridges removed so that you can diagnose
print cartridge-related problems.
PAPER PATH SENSORS This item shows the values of the sensors.
Values are updated as paper passes each
sensor. Jobs can be initiated from the control
panel or sent from the computer.
PAPER PATH TEST This item is useful for testing the paper handling
features of the printer, such as the configuration
of the trays.
MANUAL SENSOR TEST This item allows a service representative to test
the paper path sensors and switches for correct
operation.
COMPONENT TEST This item will activate individual parts
independently to isolate noise, leaking, and other
hardware issues.
PRINT/STOP TEST This item isolates print quality faults more
accurately by stopping the printer in mid-print
cycle. Stopping the printer in mid-print cycle will
cause a jam that may need to be manually
removed. A service representative should
perform this test.
COLOR BAND TEST This item allows a service representative to
identify arcing in a high-voltage power supply.
This test is only for the HP Color LaserJet 3700
series printer.
