    MX-C402SC with ppd2 jam

    We have a Shop copier with low meter 80k on black and 21k on color, it started to jam (ppd2 n2), so it became a parts machine for drum units, developer units, fuser, transfer belt. Now, I replaced maintenance items back into it to try to get it back up and working. It still has the ppd2 jams (will not pick up from tray 1 or the bypass tray), so these are the parts I have installed so far and still have the same issue. 1)Tray 1 paper feed unit 2) right door unit 3)PS sensor and PS unit 3) paper feed drive unit 4) Power Supply 5) TUD K sensor. All areas are receiving 5v and 24V
    I'm kinda stumped on this one, my next guess would be the main drive unit. Any suggestions?

      I take it that you ran motor/clutch/sensor tests before replacing the parts?

      What about wire harnesses?

      cleared error codes/list?

          Yes ran the sim 4 tested each. also cleared the codes. I will try swapping out the harness, maybe a loose wire pin.
