Lexmark MX71 series, Service Manual

Page: 232 / 807

The content of the test page varies depending on the media in the selected input source:
•
If the selected source contains paper, then a page similar to the Quick test page is printed, but without the print
registration diamonds.
•
If the selected source contains envelopes, then an envelope print test pattern is printed. This pattern contains only
text, which consists of continuous prints of each character in the selected symbol set. If Continuous is selected,
then the envelope print test pattern is printed on the first envelope; the rest are blank.
The Print Test page always prints single-sided, regardless of the duplex setting or the presence of the duplex option.
To run the Print Test:

From the Diagnostics menu, navigate to PRINT TESTS.
2

3
Select any of the following:
•
Single—Prints a single Print test page (No buttons are active while the Print Test Page is printing.)

Print Quality Pages (Prt Quality Pgs)
This diagnostic function lets the user run print quality test pages with the toner cartridge lockout function disabled.
The report consists of four pages. The printer always uses media from Tray 1 to print this report. It will not prompt for
a change in media regardless of the media type in Tray 1.
Note: This test cannot be canceled after it has begun. If duplex is activated, then the report is printed in duplex.
To print the Print quality pages:
From the Diagnostics menu, navigate to PRINT TESTS > Prt Quality Pgs.
