The Phaser 740 rear panel

Test print button

In the center of the rear cabinet panel is the test print button. Pressing this button
while the printer is idle causes the print engine to print a built-in test print. The print
consists of a field of thin horizontal lines. The print is made independently of the
image processor board. Hold in the test button for at least 4 seconds before releasing,
or until you hear the print process begin. The print demonstrates that the print engine
can print (independently of the image processor); it has no use for determining print
quality.
Note
The Test Print button will not make a test print if the auto-duplex unit
is installed since the Test Print function defaults to the upper tray.
