Abstract of the Disclosure Apparatus for registering a copy sheet prior to feeding the sheet to the image-transfer station of an electrophotographic copier. Opposing pairs of relatively rigid feed rollers are arranged on shafts in alternating relationship with opposing pairs of relatively compliant feed rollers, which are of somewhat larger diameter than the rigid rollers so as to form nips of appreciably greater extent in the direction of feed. Registration gates mounted for rotation on one of the roller shafts through slipping couplings are selectively restrained against rotation with the roller shaft either in a non-blocking position out of the feed path or in a blocking position within the nip area of the compliant rollers but upstream of the nip area of the rigid rollers. A crimper comprising an anvil rotating with one of the registration gates and a hammer supported by the anvil for pivotal movement into a recess in the anvil deforms a leading edge portion of the copy sheet as it is advanced from the registration rollers to facilitate separation of the sheet from the photoconductor after image transfer by a pickoff element spaced from the photoconductor.
