Description
Since the error code "E674-0001" was indicated and the FAX function did not work, the main controller PCB (main) was replaced with a new one for solution.
- E674-0001 can be displayed when a communication error between FAX PCB and the main controller PCB (main) is detected in the prescribed number of
times.
Cause
Since the main controller PCB (main) was faulty, it failed to communicate with the FAX PCB, causing the error code.
Field Remedy
1. Re-fit all the connectors of the FAX board.
2. Re-fit all the connectors of the main controller PCB (main)
3. If the symptom still occurs, replace the main controller PCB (main) with a new one.
4. If the symptom still occurs, replace the FAX PCB with a new one.

Description
Since the error code "E350/0000/E732-0001/E747-051B/E747-DF00/E748-4000" was displayed at start-up, the SJ-A board was re-fitted for solution.
- E732-0001 can be displayed when the DDI-S communication error occurs.
- E747-051B can be displayed when an error occurred within the Main Controller PCB (main).
- E747-DF00 can be displayed when unmounting of the Main Controller PCB (sub SJ-A) is detected.
- E748-4000 can be displayed when any ASIC of the Main Controller PCB (Sub SJ/PE/R) or ASIC of the open interface PCB is not detected.
Field Remedy
1. Re-fit the Sub SJ-A board.
2. Wipe the connector of the Sub SJ-A board with lint-free paper impregnated with alcohol, and then re-fit the board.
Note: When refitting the board, insert it as far as it will go and then tighten the screw further away from the Main Controller PCB, first.
15.3.7.33 E732-0001/E811-0001 occurs upon installation: Connector J254 hs poor contact

Description
Since J254 connector of the Controller Power Supply PCB had poor contact, the error code "E732-0001/E811-0001" was displayed.
- E732-0001 can be displayed when the DDI-S communication error occurs.
- E811-0001 can be displayed when an error in blowout of the fuse for detection of a new drum unit (process cartridge) is detected.
Field Remedy
Re-fit J254 connector of the Controller Power Supply PCB.

Description
The code "E732-9999" is not an error code. This is displayed when a printer model first detects a scanner.
Field Remedy
When this code is displayed, turn the main power switch OFF/ON.

Description
Depending on the mounting condition of a Sub PCB to the Controller PCB, the terminal of the Sub PCB has poor contact, causing the error code "E747" or
"E748."
Field Remedy
When re-fitting a Sub PCB to the Controller PCB, or when replacing a Sub PCB, perform the work by referring to the attached "E747/748: How to Modify
Connection of the Sub PCBs to the Controller Box."
15.3.7.36 E747-C000 is displayed at copying because paper jam occurs in front of registration area: DDI-S cable is faulty

[ Inspected by Canon Inc. ]
Description
At time of copying, a paper jam occurred in front of the registration area, consequently causing the error code "E747-C000." To solve this, the DDI-S cable
was replaced with a new one.
- E747-C000 can be displayed when an error occurs in communication with the main controller PCB (sub SJ).
Cause
Since the DDI-S cable was faulty, the image data scanned by the reader was input to the printer in a state in which it was corrupted. This prevented this
machine from processing the data correctly, making the paper stop in front of the registration area.
Field Remedy
1. Re-fit the DDI-S cable.
2. If the symptom still occurs, re-fit the main controller PCB (sub SJ-A).
3. If the symptom still occurs, re-fit J502 connector of the reader controller PCB.
4. If the symptom still occurs, replace the DDI-S cable with a new one.
