    Ricoh Aficio 650 Please Help

    I have a Aficio 650,
    It runs fine but on long runs it blanks out (power goes off for a few seconds then comes back on ) when it comes back on, of course it shows jammed paper in system once you clear the jammed paper and reprogram the copier it starts copying again and it does the same thing again cut off and back on

      Sounds like something could be earthing out against the chassis or maybe a switch is arcing.

          My first reaction is power supply or main power switch.
          If you'd like a serious answer to your request:
          1) demonstrate that you've read the manual
          2) demonstrate that you made some attempt to fix it.
          3) if you're going to ask about jams include the jam code.
          4) if you're going to ask about an error code include the error code.
          5) You are the person onsite. Only you can make observations.

                  You are loosing power accidentally. So somewhere on the machine you have short circuit to the ground. It can be anywhere, I had situation on lift sensor on LCT. You should look around in the machine and try to see cuted wire disconnected cable or something similar.
                  The power supply board or main PCB is not excluded.

                  Sorry Man this is my opinion. Good lack.

                      This is often caused by a high voltage corona short. Replace the entire corona assy Dont try shortcutting by replacing wire or grid only , just replac the assy. its a cheap part
