    Sharp MX-C402SC wont restart after going into energy save

    Sharp MX-C402SC wont restart after going into energy save. The light blinks like normal but when we go to restart with the power save button the blinking light goes out and nothing happens. We have replaced the MFP operation PWB but that did not make any difference. When we reboot everything comes back up to normal until it goes into power save again. Not sure where to go next.

    First, make sure the power save and auto power shut off times are different, as that can cause issues. Second, does it wake up when a print job is sent to it? We had a similar problem on a MX-B401 a while back, and after disabling WSD and mDNS in the Security Settings > Port Control, it never had another problem

      Why would you change out the MFP board before making simple changes first? Energy timer settings or HDD? Much cheaper than MFP boards.

        Sorry I did not include this info, but the first thing I tried was the power save and auto power shut off times, The Board was the power switch board from under the operation panel from a Parts machine, and I have not tried the HDD drive yet or the mfp board.

          At least you did not have to spend money on it. Try to format the HDD first before replacing it.

            The solution- While checking the HDD I noticed that one of the dimm cards was slightly askew. once it was reseated properly every thing was good. Thanks for everyone's help

              May or may not help, but firmware. Get the latest firmware and flash it even if he machine is up to date. This has helped more times then I can believe, even on machines that already had the latest firmware.
