    MP C305 SC452

    Hey guys i am having a weird issue with these MP C305's.

    I tested everything out, made sure everything is good and functioning properly, and updated the firmware. Then, I took it apart to clean it and when i reassembled and turned it on, i am very frequently getting an SC 452 error. Sometimes this error goes away after restarting the machine but sometimes it doesn't and i am stuck with what to do.

    I have cleaned all Transfer belt metal contacts and re seated the transfer belt, switched the transfer belt with a known working one, and still no luck. Anyone know why i am getting this code?

    Here is what the manual says but i don't see why i would be getting this code multiple times across different machines. Am i putting something back wrong?

    Paper transfer belt contact motor error
    The paper transfer belt contact motor drives beyond the specified time
    during home position detection or contact operation.
     Broken harness or defective connectors
     Disconnected connector of paper transfer belt contact sensor or
    motor
     Defective paper transfer belt contact motor
     Paper transfer belt unit not installed
    1. Check and replace the harness and connectors.
    2. Replace the paper transfer belt contact motor.
    3. Reinstall the paper transfer belt unit.

    Check the right door is closing fully, if not you will get SC452.
    Try holding it firmly shut, reboot & run test prints.

    Clean the sensor under paper transfer roller.
    Check the door close hooks.
    Also sometimes caused by the fuser.
