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.
1. From the Home screen, scroll to and touch the Administration button.
2. Touch the Troubleshooting button.
3. Touch the Diagnostic Tests button.
4. Scroll to and touch the Print/Stop Test button.
5. Enter a range, and then touch the OK button.
