16.3.10.14 E012-0001 Error Code: Drum ITB Motor, DC Power Supply PCB and
Fuse PCB work normally
[ Inspected by Canon Inc. ]
Field Remedy
As a result of inspection, it was found that this symptom occurred because the Door Switch Ass'y was faulty.
Check whether or not 24V is supplied to the pin 1 of the connector J71 on the Fuse PCB while the door switch
is being actuated. If not, replace the Door Switch Ass'y with a new one.
Door Switch Ass'y: FG6-9013
For your information, if 24V is not supplied to the Fuse PCB, the relay on the PCB does not work and
consequently 24V is not supplied to the Drum ITB motor that is required to drive the ITB.
16.3.10.15 E012-0001 Error Code: Because Drum ITB Motor is faulty, or Fuse
PCB is faulty
[ Inspected by Canon Inc. ]
Description
E012-0001 can be displayed when the drum ITB motor fails to rotate.
Cause
As a result of inspection, the following were found to be a cause. They are listed in order of decreasing number.
- The drum ITB motor is faulty.
- The Fuse PCB is faulty.
- Either of the open/close switches for the front cover, the manual feed tray unit or the fixing feeder unit is faulty.
- The connectors on the DC Controller PCB are not securely fitted.
Field Remedy
Follow the steps below:
1. Remove the ITB unit and check whether the belt rotates smoothly.
2. Disconnect the connector J71 from the Fuse PCB and check the continuity between J71-1 and J71-3 with a
tester. If no continuity is verified, it indicates that either of the three switches above is not turned ON.
3. Check whether the drum ITB motor J93-1 is supplied with DC24V from the Fuse PCB J70-3. If not, replace
the Fuse PCB after checking the connection of the connectors on it.
4. Check whether the drum ITB motor J814-2 is supplied with DC5V from the DC Controller PCB J105B-16. If
not, replace the DC Controller PCB after checking the connection of the connectors on it.
5. If no problem is found in the Step 1 through 4, replace the drum ITB motor with a new one.
