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 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/Empty=OP/Pass=OP" message displays.
•
EM = Input Tray Empty Sensor
•
LO = Input Tray Paper Low Sensor
•
P = Input Tray Pass Thru Sensor
2. 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.
3. Press Return/Stop to exit the test.
The multipurpose tray and the envelope feeder do not have a paper
low sensor. The multipurpose tray does not have a pass thru sensor.
