    Replacing the CPU under the control panel resolved the problem.

    imageRUNNER ADVANCE C5030 / C5035 / C5045 / C5051 CPU PCB assembly is FM3-7994-000

    or-------------------
    Sometimes dirt can buildup between the touch panel and the control panel cover. This buildup over time causes downward pressure to the touch panel and it stops responding. Going around the entire perimeter of the screen, take a business card or other firm type of media and slide it between the touch panel and the control panel cover.

    or try1. Turn OFF the main power switch and check that the Control Panel LED is off
    2. Using a pen point, press the test button of the breaker on the rear side of the machine
    3. Check that the breaker switch is OFF (O side)
    4. Return the breaker switch to ON (I side)
    5. Turn ON the main power switch
    hello I have the same problem with a canon irac5235, perform dirt cleaning between the touch panel and the control panel cover, check panel pcb connector and main controller. Press the switch test button on the back of the machine off and on. the printer was turned on again and the control panel worked well, the next day the control panel presented the same problem. when I press the switch test button on the back again, the printer control panel works fine. Is it necessary to change PCB assembly is FM4-9880-000 or update the firmware ?. I don't have the firmware to be able to perform the update

    A client has an IRA c5250 with a control panel that was AFU. The 'Energy Saver' key functioned OK.
    I installed a salvaged control panel ass'y that I obtained from a buddy; it incorporated PCB P/N FM1-R833.
    Problem solved.
    Plug and play, no software upgrade needed.
    Life is (sometimes) good.

    I have a Canon IRA C5235A, the board is new style "FM1-R833" already. But it was frozen screen. I touched the power saver button, it went off, but couldn't turn back on. I have to power off the machine, and power back on, then the touch screen works OK. Do you think it is another problem?
