4040 Finisher
Service Checks
Alignment Plate Shift Motor Service Check
Distance Detecting Sensor Service Check
1
Connector
Be sure J11 is properly connected to the finisher
driver board.
2
Alignment
Plate Shift
Motor, M2, (5-
21)
Unplug J11 from the finisher driver board. Measure
the resistance between J11-1 and J11-2/ -3/ -4/ -5
on the motor side. If it does not read approximately
16 Ohms, replace the alignment plate shift motor
(PN 11D0162).
3
Finisher Driver
Board (13-1)
If there is still a problem, replace the finisher driver
board (PN 11D0294).
FRU
Action
1
Connector J6
Be sure the distance detecting sensor signal line
connector (J6) on the finisher driver board is
properly connected.
2
Distance
Detecting
Sensor, PS1
(3-26)
Measure the voltage between J6-4 (GND) and J6-2
(Vcc)/-3(Vin) on the finisher driver board. If it is not
5 V, replace the distance detecting sensor
(PN 11D0074).
3
Finisher Driver
Board (13-1)
If there is still a problem, replace the finisher driver
board (PN 11D0294.
