Input tray tests

Input Tray Feed Test

This test lets the servicer observe the paper path as media is feeding through the printer. A blank
sheet of paper feeds through the printer as the laser turns off during this test. The only way to
observe the paper path is to open the lower front door that is used to access the envelope or
multipurpose feeder. The paper is placed in the output bin.
To run the Input Tray Feed Test:
1.
Select Input Tray Feed Test from the menu.
2.
Select the input source from the sources displayed on the Feed Test menu. All installed sources
are listed.
3.
Select either Single (feeds one sheet of media from the selected source) or Continuous
(continues feeding media from the selected source until Return/Stop is pressed).
4.
Press Return/Stop to exit the test.

Input Tray Sensor Test

This test is used to determine if the input tray sensors are working correctly. To run the Input Tray
Sensor Test:
1.
Select the Sensor Test from the Input Tray Test menu.
•
"Input Tray/Emptying/Pass=OP" message displays.

Once this message displays, the servicer can manually actuate each sensor. The tray empty
sensor can be actuated by hand, however a sheet of paper can be used to cover the pass thru
sensor. When the sensor is closed, CL displays, when the sensor is open, OP displays.
