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.
