    C4503

    I have a situation, I purchased a lot of 10 machines and one of them (MPc4503) has had the motor speed changed to 55 cpm. I do not want to resell it this way because the serial # tag does not match ( very unethical) I have found in the factory service mode the cpm address but am unable to reset it. Please PM me if there is a method to reverse this.
    Thanks

    I think you're stuck with it. Sell it as a 45 cpm machine, it won't matter if it's a little faster.

    I'm of the opinion of simple full disclosure. You bought machines used for resale without being able to fully vet their histories. You got one that was altered in some way. If it works and you are willing to stand behind it there should be no issue. Just be honest, works almost every time.

    Sounds to me like someone replaced the controller PCB. The part numbers for the C6003, C5503 and C4503 controllers are different. There is also the possibility that someone had 2 machines, a 45 that didn't work but had a full set of usable covers and with no covers but worked.

    I think he's really just fishing for an answer on how to change the speed, so he can speed up his machines.

    I agree that if you are going to warranty it and service what s the big deal?
    If you think it will crap the bed then GUT IT for parts...

    I don't believe the speed change is from a motor change. It is by more efficient paper timing. Agree that probably more than one board would need to be changed to make it run at the 55 speed. I believe as mentioned, you have a 55 with the wrong front cover label or it is simply listed wrong in SP5907. Does it actually run faster or does it just identify itself as a 55 in WIM?

    If you have a serial number mismatch sounds like the machine has had an NVRam replacement possibly to reset the counter etc.

    You can't simply change the machine speed.
