Hi all. I'm having a problem with jams on the b6200.Two thirds of the paper exits the machine and then jams.The machine may run for a few pages and then jam again.So far i have checked and replaced paper trays feed rollers,the fuser unit the feed and reg assembly which contains the reg switch.After changing the exit rollers and reg assembly the machine printed over a thousand prints on test on two different occasions but i noticed when testing the machine first thing in the morning it starts jamming again.Im not sure if this is a cold condensation problem with one of the paer sensors or main controller problem. Has anybody seen a problem like this.
