Print 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. Each of the installed options is listed in the following order in the menu:
Tray 1
Tray 2 (if installed)
Tray 3 (if installed)
Tray 4 (if installed)
Tray 5 (if installed)
Multipurpose Feeder (if installed)
Envelope Feeder (if installed)
For each input source selected you have the following choices:
•
Single (prints the Print Test Page once)
•
Continuous (continue printing the Print Test Page until Return or Stop is pressed).
The contents of the Print Test Page varies depending on the media installed in the selected input
source.
Note: The Print Test Page always prints on one side of the paper, regardless of the duplex setting or
the presence of a duplex option.
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.
To run the Print Test Page:
1.
Select Print Tests from the Diagnostic menu.
2.
Select the media source.
3.
Select Single or Continuous.
•
If Single is selected no buttons are active during printing.
•
If Continuous is selected, Return or Stop can be selected to cancel the test.
Check each Test Page from each source to assist in print quality and paper feed problems.
