    Konica 7228 copier

    Anyone ever have one of these models turn off/on by itself? We've tried firmware update, no joy. We're thinking of replacing the operation panel next. Let me know if you have had this problem and what the fix was. Thanks.

    weekly timer could be the problem or the auto low power and auto shut off off set to low. check the wall outlet and make sure no short in it...........

    Copier turns off/on while the customer is using it to make copies. I should have mentioned this. Thanks for the input.

    well then. make sure firmware is up to latest levels.
    connect your meter to the wall outlet and watch it while copies are being made. does the voltage drop any at anytime?

    Smile PSU

    Possibly a Power Supply issue. Does it turn back on right after the power goes off? If so, the main control board could be losing it's power to operate. Like the other suggestions; check the power into the copier from the wall and monitor the power while in usage. If the power is okay, then look at causes of PSU, wiring to MCB from PSU or some load on the system while copying... Does it only happen when finishing?, Duplexing, etc.
    After all is said and done, More is said than done.
