TEST Allows a service representative to test the paper-path sensors and switches for correct operation.
COMPONENT TEST Activates individual parts independently to isolate noise, leaking, and other hardware issues.
PRINT/STOP TEST Isolates print-quality issues more accurately by stopping the printer in mid-print cycle. Stopping the
printer in mid-print cycle causes a jam that might need to be removed manually. Only a service
representative should perform this test.
