Tray 2, Tray 3, Tray 4, Lift Motor
his test turns on the specified motor and runs it at constant velocity for approximately 20
revolutions while recording drive data. The test is the same for each motor. Requesting a test for
a 525-sheet feeder that is not installed will generate an “Option Not Detected” message.
