Test pages

Printing test pages helps you determine whether or not the printer engine and the formatter are functioning.

	Engine test page
	To verify that the printer engine (all printer components except the formatter, formatter DIMMs,
	EIO products, and the stacker or stapler/stacker) is functioning, print an engine test page. Use a
	small, non-metallic, pointed object to depress the test-page switch, which is located on the right
	side of the printer (callout 1).
	The test page should have a series of vertical lines. The test page will print from the last tray you
	printed from. However, if the printer has been turned off and then back on since the most recent
	print job, the page will print from tray 2. The printer will continuously print test pages as long as
	the test-page switch is depressed. The printer will not print a test page if it is in PowerSave
	mode.
Hint	A damaged formatter might interfere with the engine test. If the engine test page does not print,
	try removing the formatter and performing the engine test again. If the engine test is then
	successful, the problem is almost certainly with the formatter, the control panel, or the cable that
	connects them.
