      yes, are you getting a FALSE 13.20 error? There is a big problem with the fuser wrap detect circuit. If you have a fuser with a bad sensor or if the sensor arm shorts in it it will blow the DC controller. If you change the fuser, the DC controller will blow the new fuser. You have to change the fuser and the DC controller at the same time. Also can cause a problem if the HVPS is not installed correctly or if the 2 large contacts under the HVPS get bent or out of position.
      Life should NOT be a journey to the grave with the intention of arriving safely in an attractive and well-preserved body, but rather to skid in sideways - Coke in one hand - chocolate in the other - body thoroughly used up, totally worn out and screaming "WOO-HOO, what a ride!".

          Did some reading and then I had my own 9000 jamming. Hp manual said to look at toner cartridge as a possible. I removed cartridge and did a thorough paper path feed, synch, and registration roller cleaning. problem stopped as soon as I cleaned the rubber roller just before the transfer unit. Remove small plate with the static brush on it. Its been fine since. Worth a shot.
