Print tests
Input source tests
The purpose of the diagnostic Print Tests is to verify that the printer can print on media from each of the installed
input options. The contents of the Print Test Page varies depending on the media installed in the selected input
source.
Check each Test Page from each source to assist in print quality and paper feed problems.
To run the Print Test Page:
1.
Select PRINT TESTS from the Diagnostics menu.
2.
Select the media source.
Tray 1
Tray 2 (if installed)

Select Single or Continuous .
•
If Single is selected, a single page is printed.
•
If Continuous is selected, printing continues until Stop ( )is pressed to cancel the test.
If a source is selected that contains envelopes, an envelope test pattern is printed. If Continuous is
selected, the test pattern is printed only on the first envelope.

Print quality pages (Prt Quality Pgs)
This setting enables a user to view the values of a broad range of the device’s settings and to test the device’s
ability to generate acceptable printed output. After a user selects this option, the printer begins generating 5
pages in English. The device always uses the media that is currently installed in Tray 1 to print this report; it will
not post a Change Media prompt regardless of the media currently installed in Tray 1. While these pages print,
the panel displays, “Printing Quality Test Pages”. Once started, printing cannot be canceled and all key presses
are ignored until printing completes.
To run the Print Quality Test Pages, select Prt Quality Pgs from PRINT TESTS. The message Printing
Quality Test Pages is displayed.
