Be sure J5, J11, and J13 are properly connected to
the finisher drive board.
Unplug J5 from the finisher driver board. Measure
the resistance between J5-9 and J5-10 on the
switch side. If the resistance is not 0 Ohms with the
swing guide down, or infinity with the swing guide
up, replace the swing guide close detecting switch
(PN 11D0139).
Unplug J5 from the finisher driver board. Measure
the resistance between J5-11 and J5-12 on the
switch side. If the resistance is not 0 Ohms with the
swing guide down, or infinity with the swing guide
up, replace the swing guide close sensing switch
(PN 11D0139).
Measure the voltage between J13-5 and J13-6 on
the finisher driver board. If it is not 0 V with the
swing guide down, and not 5 V with the swing guide
up, replace the swing guide open sensor
(PN 11D0071).
If there is still a problem, replace the finisher driver
board (PN 11D0294).
Be sure J7 is properly connected to the finisher
driver board.
Unplug J7 from the finisher driver board. Measure
the resistance between J7-4 and J7-5 on the motor
side. If it does not read 5.5 Ohms, replace the tray
elevation motor (PN 11D0254).
If there is still a problem, replace the finisher driver
board (PN 11D0294).
