The purpose/function of a registration system is to align a copy sheet with an image on a photoreceptor prior to transfer of that image to the copy sheet. One method for accomplishing this includes the use of a stalled roll registration system consisting of a nip formed between a driver roll and a spring loaded idler roll. The rolls are 10 mm wide and mounted to a shaft approximately 175 mm apart. The lead edge of a copy sheet is driven into the nip and stopped while the trail edge of the copy sheet continues to be driven for a short period of time. This action causes a buckle to form between the nip/gate and pre-registration drive roll.
