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.
