that will display the last 50
entries in the printer’s event
log, starting with the most
recent.

DISABLE CARTRIDGE CHECK This item allows you to remove
a print cartridge to help
determine which cartridge is
the source of the problem.
Paper Path SENSOR TEST This item performs a test on
each of the printer’s sensors to
determine if they are working
correctly and displays the
status of each sensor.
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 performs a test to
determine whether the paper
path sensors are operating
correctly.
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 allows you to
see where the image begins to
degrade. 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.
