Input Tray Tests
Feed Test
This test lets you 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 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 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.
Sensor Test
This test is used to determine if the input tray sensors are working
correctly.
To run the 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
– IN = Input Tray Inserted Sensor
2. Once this message displays, you 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 through
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 through
sensor.
