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 Stop to return to the DIAGNOSTICS menu before the timer times out.

After the timer times out, press Stop. Activate the door switch to restart the engine and return it to a normal state.
