Media Path Motor Test
The Media Drive motor is run slowly CCW for one revolution. The slow motion removes the
effect of inertia from the test, and the one revolution avoids a large system status change via
any permanently connected loads. With the slow operating speed used by the test, the motor
may stall at a bad commutator segment. The connected gear train effects the drive average
and ripple values due to the load variation with gear train position. Unusual average values
might indicate a weak motor. The motor following error, drive voltage, and power ripple values
indicate how smoothly the motor is able to turn through one revolution. This test will not run if
media is detected in the paper path.
Tray 2, 3, and 4 Lift Motor Test
The specified Lift Motor is turned on and run for a period of time sufficient to advance the lift
plate drive gear one tooth (about 20 revolutions). Next, the motor is turned off and the brake
momentarily applied. Selecting a test for an undetected optional feeder generates an Option
Not Detected message and the test aborts. Also, the test aborts if the selected tray is installed.
Tray 3 and 4 Pick/Feed Motor Test
The selected motor is turned On and allowed to reach a constant velocity. Motor drive data is
then recorded for a fixed interval (approximately 25 motor revolutions). The connected gear
train effects the drive average and ripple values due to the load variation with gear train posi-
tion. The motor following error, drive voltage, and power ripple values indicate how smoothly
the motor is able to turn through one revolution. Selecting a test for an undetected optional
feeder generates an Option Not Detected message and the test aborts. This test will not run if
media is detected in the paper path.
