    How much sheets has the fusing unit run through? Maybe the fusing belt or/and the lower fusing roller are worn, causing paper stick to the roller and push the sheet beneath the separation claws.

        When do the jam occurs during 2 side printing? 1st side or 2nd side?
        Does the sheet runs beneath the upper or the lower claws?

          Had a similar problem with one of my units but was caused by bent stripper plate unit (D0144300). The plate was not visible bent but I was able to determine that the pressure was not even. Maybe was a difference in pressure between the Front Torsion Spring and Rear Torsion Spring - Stripper...I can not tell you because I ordered and replaced all, including the Bracket - Exit Unit. If the fuser is really hot and customer opens to clear a jam and slam it back...could cause a damage that is almost impossible to determine visually. If are well maintained these fusers can last 700K...moment when personally I'm replacing the entire unit because everything is "cooked" inside: harness, lamps connectors are cracked and it's a metal fatigue that can not be stopped.

              We've had a number of MPC6000/7500's have corners catch on the upper stripper "blades" usually the most op-side one, usually on units with relatively low page counts. Usually moving the blade a little closer by turning the adj. screw 1/2 to 1 turn CCW has taken care of it.
