Troubleshooting Procedure (continued)
Step Actions and Questions
23 Check the Left Side Harness Assy for
continuity.
Disconnect J23 from the MCU Board.
Disconnect P231 from the Feed
Solenoid.
Is each wire of the harness
continuous?
24 Disconnect J23 from the MCU Board.
Press the Interlock Switch (Interlock
Harness Assy) while Measuring the
voltage across P23-1 <=> ground on
the MCU Board.
Is the voltage about +24 VDC?
25 Check the Feed Solenoid for resistance.
Disconnect P/J231 of the Feed
Solenoid and measure the resistance
across J231-1 and J231-2.
Is the resistance about 96 ohm?
26 Check the connections between the
MCU Board and Registration Sensor.
Are P/J23 and P/J232 connected
correctly?
NOTE Access to the Registration
Sensor requires removal of the
Upper Frame (SFP, page 8-51;
MFP, page 8-67).
27 Check the Left Side Harness Assy for
continuity.
Disconnect J23 from the MCU Board.
Disconnect J232 from the Registration
Sensor.
Is each cable of J23 <=> J232
continuous?
28 Check the power to the Registration
Sensor.
Disconnect J23 from the MCU Board.
Measure the voltage across P23-3 <=>
ground on the MCU Board.
Is the voltage about +3.3 VDC?
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?
