    Re: U2-74

    Hi

    Error U2-74 indicates a problem with firmware recovery and can be reset by the operator by acknowledging (OK) the error display.

    On devices that are not switched off overnight, the device firmware is checked at 3:00 a.m. If a change in the firmware is detected during this check, the original firmware is restored. This is a security function that prevents manipulation of the device firmware. This function can be activated/deactivated in the security settings of the device.

    Hi,

    I have also experience this issue. I tried a firmware update and then tried the CN Update. Sharp recommended the eMMC/mSATA card, which I replaced, but the problem wasn't resolved until I replaced the MFPC unit.

    Any idea where you can deactivate this setting?

    Or do you have that Technical Report? Because there is no such report in BeNeLux

    Because changing the motherboard on a crapload of machines that are throwing this error doesnt seem like an option.
