摘要： Sheet feed apparatus including a scuff feed for reliably transporting sheets from different types of sheet stacks and different types of sheets within the stack. The apparatus comprises a sheet feed roller and a retard device in contact with the feed roller. A nudging device, contacting a paper stack, is used to feed single or multiple sheets into the nip between the feed roller and retard device. The feed roller, retard device, and nudging device all have a surface layer of 35-28092-N-GY-A, which gives them a much longer useful lifetime. A method for maximizing the efficent use of these rollers and of testing and using these rollers is also disclosed.
