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 through sensor. When the sensor is closed, CL displays, when the sensor is open, OP displays.

3.Press Return/Stop to exit the test.
