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. Select OK to print the previously selected job. If you do not want the previous job to print, select Stop.

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.
