Value Actions
0 Motor fe ripple
(ticks)
.4 to 1.3 Reports amount of variation of the motor
following error over the recording interval.
1 Motor fe average
(ticks)
0.8 to 2.0 Reports the motor following error average
value of the recording interval.
2 Motor drive voltage
ripple (volts)
4 to 10 Reports amount of variation of the motor drive
voltage over the recording interval.
3 Motor drive voltage
(volts)
-5 to 0 Reports the motor drive voltage average value
of the recording interval.
4 Motor drive power
ripple (watts)
0.8 to 6 Reports amount of variation of the motor drive
power over the recording interval.
5 Motor drive power

of the recording interval.
Tray 2, Tray 3, Tray 4, Lift Motor
This 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.
