Error Messages and Codes
15 Check the power to the Photo Sensor
Disconnect J23 from the MCU Board.
Is the voltage across P23-3pin <=>
ground on the MCU Board, about +3.3
VDC?
Go to step 16. Replace the
MCU Board
(page 8-59).
16 Check the Photo Sensor for operation
Check the voltage across J23-5 <=>
ground on the MCU Board.
Does the voltage change, when the
Regi Roll Actuator is operated?
Replace the
MCU Board
(page 8-59).
Replace the
Feeder
Assembly
(page 8-25).
17 Check the connectors of the Drive
Clutch Assy (Regi Clutch) for
connection
Check the connections between the
MCU Board and Drive Clutch Assy.
Are P/J26 and P/J262 connected
correctly?
Go to step 18. Reconnect the
connector(s) P/
J26 and/or P/
J262 correctly.
18 Check the power to the Drive Clutch
Assy (Regi Clutch)
Disconnect J26 from the MCU Board.
Is the voltage across P26-4pin <=>
ground on the MCU Board, about +24
VDC when the Front Cover Interlock
Switch is pushed?
Go to step 19. Replace the
MCU Board
(page 8-59).
19 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
(page 8-59).
Replace the
Drive Clutch Kit
(page 8-21).
20 Check the connections between the
MCU Board and Main Drive Assembly
(Main Motor).
Are P/J21 and P/J211 connected
securely?
Go to step 21. Reconnect the
connector(s) P/
J21 and/or P/
J211 securely.
21 Check the power to the Main Drive
Assembly
Disconnect J21 from the MCU Board.
Are the voltages across J21-2/J21-4
<=> ground on the MCU Board, about
+24 VDC when the Front Cover
Interlock Switch is pushed?
Replace the
Main Drive
Assembly
(page 8-52)
Replace the
MCU Board
(page 8-59).
