ABSTRACT OF THE DISCLOSURE An automated sheet-feed apparatus for feeding cut sheet paper to an automated printer includes apparatus for forming a predetermined length of buckle in the sheet of paper. The sheet-feed apparatus feeds the leading edge of a sheet of paper into a nip formed by the platen and the first set of pressure feed rollers of the printer. As feeding of the sheet of paper continues, a predetermined length of buckle is formed in the buckle chamber, at which time feeding by the sheet-feed apparatus is stopped. The printer platen drive system feeds the leading edge of the sheet through the nip and to a second nip formed by a second set of pressure feed rollers and the platen before the buckle is eliminated in the sheet of paper, and while the retard force from the sheet-feed apparatus is not apparent to the printer platen drive system.
