5510 konica minolta dog earing copies in duplex mode. paper seems fine. single sided copies are great. but in duplex once in a while (every 3 or so. it will dog ear the copy) I took my time and took the sync clutch and the upper assembly where it lifts. out. and cleaned. but it still will jam. there is an attatchment here that is a copy it is catching on something and turning the paper sideways and it prints onto the paper (which is crooked) what do you guy's think? also the dog ear is on the leading edge. thanks for your help
