Troubleshooting Procedure (continued)
Step Actions and Questions
12 Disconnect J23 from the MCU Board
and measure the voltage across P23-3
<=> ground on the MCU Board.
Is the voltage about +3.3 VDC?
13 Check the voltage across P23-5 <=>
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?
14 Check after replacing Duplex Unit.
Replace Duplex Unit. (page 8-162)
Does the error still occur when
printing?
15 Check after replacing Fuser Assy.
Replace Fuser Assy.
Does the error still occur when
printing?
NOTE: After replacement, be sure to
clear life counter value.
