Field Remedy
1. Check the front and under sides of J423 connector (11 pins), which connect when the fixing feeder assembly is set into the main body, for poor contact. If
pins are deformed, modify them and then connect the connector.

2. Check J3416 connector on the side driver PCB and J3419 connector that extends from the same PCB to the DC controller PCB for poor connection. If pins
are deformed, modify them and connect the connectors again.
3. If the pre-exposure LED did not come on because of poor contact of the connectors, the drum potential may not be controlled normally. Modify the
connectors and turn the main power switch OFF and then ON to make the machine perform an initial rotation.
4. If no problem was found with the connectors in Step 1 and 2, check J431 connector in the LED side (pre-exposure LED) and J425 connector (photosensitive
drum cleaning pre-exposure LED) for poor contact. If pins are deformed, modify them, and then re-fit the connectors.
5. Perform Step 3 again.
6. If the symptom still occurs, check J1167 connector on the DC Controller PCB. If pins are deformed, modify them, and then refit the connector.

[Inspected by Canon Inc.]
Description
Since the tie-wrap [1] binding the ATR shutter solenoid cable was fitted in the wrong position, the cable went slack and came into contact with the developing
cylinder, causing void in the sub scanning direction.
