i have a c3200 i just took a look at. it is jamming 9 out of 10 times entering the fuser from all trays. there is a high pitched 'whine' coming from behind the cover just behind the fuser 'tray'. while it is whining, the exit roller isn't turning. is there a problem with the fuser drive on these? thats where it sounds like the noise is coming from. the exit rollers do turn at warmup but maybe thats a different speed on the motor.
