Registration clutch and possibly registration roller assy. Timing at ppd2 is varying making machine believe paper size is wrong.

Dave is correct. You can try cleaning the sensors on the PWB to the right side of the door under the by-pass. They detect size as paper passes & they're staying active too long. More the likely resist clutch or clutches in the pack on the back.
