Input Tray Tests
Input Tray Feed Test
The Feed Test operation within the INPUT TRAY TESTS menu is used by the
manufacturing line and service engineers to observe the paper path as media is being fed
through the printer. The upper front door (used to access the print cartridge) cannot be
opened during the feed test. To observe the paper path, users must open the lower front
door (used to access the envelope feeder or multi-purpose feeder). No information is
printed on the feed test pages since the laser isn’t engaged during this test.
Note: The feed test can be run using any of the paper and envelope sizes supported by
the printer.
The pages are placed in the default output bin. However, the Feed Tests menu lets you
select the input source. Each of the installed sources is listed as an option within this
menu. For each source, the user has two choices:
• Single (feed one sheet of media),
• Continuous (continue feeding media until Return or Stop is pressed).
While the page is being fed, the following message is displayed. The Power indicator
blinks while the page is being fed.
If Single is selected, no buttons are active during the feed test. However, if Continuous is
selected, Return or Stop can be pressed to cancel the test. While the test is being
cancelled, the following message is displayed.
Note: <input tray> represents the input source selected for the Print Test. One of the
following sources is displayed: Tray 1, Tray 2, Tray 3, Tray 4, Tray 5, MP Feeder, or
Envelope Feeder.
