Error Messages and Codes
29 Check the voltage across J23-5 <=>
ground on the MCU Board.
Remove the Lower Chute Assembly
(page 8-84; PL3.2.27) to check the
operation of the Registration Sensor.
Does the voltage change when you
operate the Registration Input
Actuator?
Replace the
MCU Board.

page 8-160)
Replace the
Registration
Sensor
(page 8-80)
30 Check the connections between the
MCU Board and Drive Clutch Assy.
Are P/J26 and P/J262 connected
correctly?
Go to step 31. Reconnect the
connector(s) P/
J26 and/or P/
J262 correctly.
31 Check the K-Sensor/Regi Clutch
Harness Assy for continuity.
Disconnect J26 from the MCU Board.
Disconnect P262 from the Drive Clutch
Assy.
Is each cable of J26 <=> P262
continuous?
Go to step 32. Replace the K-
Sensor/Regi
Clutch Harness
Assy.
32 Check the power to the Drive Clutch
Assy.
Disconnect J26 from the MCU Board.
Is the voltage across P26-4 <=> ground
on the MCU Board, about +24 VDC
when the Interlock Switch (Interlock
Harness Assy) is pushed?
Go to step 33. Replace the
MCU Board.

33 Check the Drive Clutch Assy for
resistance.
Disconnect P/J262 of the Drive Clutch
Assy.
Is the resistance across J262-1 and
J262-2 approximately 280-ohm?
Replace the
MCU Board.
