    RICOH MPC4000

    Hello friends I wonder if someone had this problem.
    When connecting the equipment with open swicht, loading equipment, but at the time of closing the covers, it makes short electrical energy.
    I checked psu, wired aparantemente are fine.

    Well, while we will need more information to make a reasonably accurate response, you might review this to make sure that location has an adequate power supply for that machine:

      You might have a short in the fusing unit. Remove fusing unit to test.

        Turn the machine on with the front door and right door both open, to disengage the laser and fuser. If it still shorts check the PSU, then scanner, and finally all connectors you can find.

        Sometimes I have found a damaged right hand door wire that was making contact with the frame, so check those too.

          It will almost certainly be the IH inverter board, behind cover to the right of the fuser assy.
