Sensor Test (Input Tray); Output Bin Tests; Feed Tests (Output Bins) - Lexmark T650 Service Manual

Feed Tests (input tray)
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.

listed.
3. Select either Single or Continuous.
•
