Printing test prints on the Phaser 750 printer
The prints printed via the front panel are generated by the image processor. While
the printer is idle you can use the front panel to print an image stored in the image
processor such as the Configuration Page.
Printing the Diagnostic Test Pages and Solid Fill Test Page
The Diagnostic Test Pages prints allow you to evaluate the printer’s print quality. The
pages consist of four pages of 25% tint primary color fills, one page of all for colors at
25% fill, and a page describing how to interpret the prints. The Solid Fill Test Page
prints a solid-fill red print.

Printing the print engine’s test print
The print engine can print a test print independent of the image processor. The print
is a composite gray fill composed of cyan, magenta and yellow toner. No black toner
is used in the print.

Press and hold for 10 seconds the Test Print button in the center of the upper
rear cover.
This verifies the print engine’s ability to print independent of the image processor. Do
not use this print to verify print quality. Since the print engine defaults to the top tray
as a paper source, the Test Print function will not work with the auto-duplex unit
installed.
