Input Tray Tests

Feed Test

This test lets you observe the paper path as media is feeding 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, you must open the
lower front door, used to access the paper jams on the vacuum transport belt. Blank pages feed during the test.
Note: This test can run using any of the paper or envelope sizes supported by the printer. The pages are placed
in the default output bin, however, the Feed Test menu lets you select the input source.
To run the Input Tray Feed Test:
1.
Select Feed Test from the menu.
2.
Select the input source from the sources displayed on the Feed Test menu. All installed sources are
displayed.
3.
Select either Single (feeds one sheet of media from the selected source) or Continuous (continues to
feed from the selected source until Return or Stop is pressed).
4.
Press Return or Stop to exit test.

Sensor Test

This test can be used for either 500-sheet trays or 2000-sheet trays.
500-sheet trays
Use this test to determine if the input tray sensors for a 500-sheet tray are working correctly.
