NOTE: Exiting the Paper-path sensor test menu and then reentering it will clear the test values
from the previous test.
Viewing the sensor status before you activate the test should show that the sensors PS9, PS11 and
SW5 have already been activated. After running the Paper-path sensor test, sensor PS9 does not
show any activation status.

Print/stop test
Use this diagnostic test to isolate the cause of problems such as image-formation defects and jams
within the engine. During this test you can stop the paper anywhere along the product paper path. The
test can be programmed to stop printing internal pages or an external print job when the paper
reaches a certain position. The test can also be programmed to stop from 0 to 60,000 ms. If the timer
is set to a value that is greater than the job-print time, you can recover the product in one of two ways.
●
After the print job is completed press the Stop button
to return to the Diagnostic Tests menu
before the timer times out.
●
After the timer times out, press the Stop button
. Activate the door switch to restart the engine
and return it to a normal state.
When the timer trips, the control panel display shows the message Printing stopped To continue,
press OK. Pressing the Home button
will print the previously selected job. If you do not want the
previous job to print, press the Stop button
first, and then press the Home button .
NOTE: Do not try to perform a print/stop test while the product is calibrating, because you will be
required to power-cycle the product. If a jam message displays on the control panel during testing,
activate the door switch.
