Printing Quality Pages
The purpose of this diagnostic function is to allow printing of the print quality test pages
with the toner cartridge lockout function disabled. The print quality pages consist of four
pages. Page one contains a mixture of graphics and text. Page two is gray with two one-
inch black squares located on the bottom right. Page three is a solid black page and page
four is blank. If duplex is turned on, the pages are duplexed. The Print Quality Test pages
are printed in English and must always be printed on letter, legal, or A4 paper.
To run the Print Quality Test Pages, touch
PRINT TESTS. The message "Printing Quality Test Pages" is displayed.
Note: The print quality test pages can also be printed from the Configuration menu
(CONFIG MENU), however, a cartridge must be installed with a machine class ID
matching the machine class ID stored in NVRAM. Additional diagnostic information
may be printed on the pages when printing from DIAGNOSTICS.
