Print/Stop Test
This diagnostic test can be used to isolate the cause of problems, such as image formation
defects and jams, within the engine. This test allows you to stop the paper anywhere along
the printer's 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 it
takes to print the job, there are two ways to recover the printer.
