    MP C4501 not waking up

    Hello

    I have an MP C4501 that is refusing to wake up after going to sleep...

    First thing I did was update firmware, which made no difference.

    Then I replaced the control panel, checked connections to control panel and BCU etc.. but still no joy.

    Anyone have any suggestions before I try BCU ?

    Could it be power supply perhaps?

    Thanks

    Assuming you have updated the PowerSaving Sys to F.19, try disabling STR (Suspend-to-RAM), cycle the power off / on and give it a test.

    Hello Cipher

    Thanks for the suggestion.. that seems to have resolved it.

    What is the reasoning behind this causing a problem?

    Thanks

    STR has been known to be a little bit temperamental on some Ricoh controllers depending on the peripheral configuration.
    Sometimes a firmware update can fix it, but the workaround is just to disable the feature which is enabled by default.

    Thanks for the update, machine now seems fine.

    I'll add this to our list of issues we've not seen for future reference.

    Thanks again.
