    Should have said currently i I have a c452 which can go for a week with little or no codes but then have 4 or 5 in a day, reboot and it starts going again but as you can imagine customer isn't very happy.

    To me it sounds like a motor problem.
    I had similar issue with developing motor and fuser motor (on different models) but pattern was the same (code once a month or every few days...). After replacement dode didn't come back any more.

    The typical problem we saw when the customers was using non-OEM toner was that the machines would throw the code in the morning. I think the friction of the cleaning roller was to high when the machine was cold inside.
    This problem went away after convincing the customer to use OEM toner.

    The transfer belt cleaning motor M38 or drive is beginning to fail or blown ICP18
    Clean out all of the tbu waste system and try again.
