    check the safety switches at the rear that are activated by closing the side door and also the small push switch inside the front door, either of these can give you the codes that you mention.

    The charge unit is shorting out. Replace the charge wire, grid or the charge unit

    By any chance are you using 50ppm drums in 25-30ppm machines? On the 5050 range we had few mishaps using the "slow" drum in faster m/c and vice versa.

    Dear friends,
    I thank you all for your respond, please try to understand me, I've checked both left side door switch, front door switch and the main charger grid, and the c4200 will still be there until i change the main board. I replace cleaning lamp according to the service manual but c5300 will still be there until i change the main board. so what i am asking you is this ,is it possible to CLEAR this codes from the main board.

    Thanks, waiting for you respond please.

    Did you do a 906? Did you open and close the transport with the machine on? Then you cleared the code.

    Higher in U900's there is list of system errors if memory serves me well. Not U904, something higher.

    Hi Tonerkiller,
    Can u906 clear this code? believe me i don't know, i will try this tomorrow, i only use this u906 when am having cassette problem. . but what do you mean by transport with the machine on, because the machine does not show sign of driving, it's only the fans that will On, the machine will display c4200, the main motor will not drive.

    Thanks
