Check for, and replace any broken or worn gears.
Unplug J14 of the reversing solenoid. Measure the
resistance between J14-1 and J14-2 on the
solenoid side. If it does not read 125 Ohms, replace
the reversing solenoidm (PN 11D0114).
Set the DIP switch (SW1) on the finisher driver
board so that 3 is on. Press the push switch (SW3)
to execute mechanical checking. If the paper feed
motor does not rotate, replace it (PN 11D0118).
If there is still a problem, replace the finisher driver
board (PN 11D0294).
If there is still a problem, replace the paper deck
driver board (PN 11A8461).
If there is still a problem, replace the option
controller board (PN 11D0326).
If there is still a problem, replace the printer
controller board (PN 11A8254).
Action
Be sure J7, J9, and J10 are properly connected to
the finisher driver board.
Unplug J7 from the finisher driver board. Measure
the resistance between J7-1 and J7-2 on the switch
side. If it does not measure infinity with the shutter
down, replace the shutter close sensor
(PN 11D0071).
Measure the voltage between J9-8 and J9-9 on the
finisher driver board. If it is not 0 V with the shutter
up, or not approximately 5 V with the shutter down,
replace the shutter open sensor (PN 11D0071).
If there is still a problem, replace the finisher driver
board (PN 11D0294).
