Abstract: An electrostatographic printing apparatus comprises a charge receptor (10), and a transfer station for transferring a toner image from the charge receptor (10) to a sheet (S). The sheet passes through a nip formed between the charge receptor (10) and a moving transfer belt (30). Upstream of the nip, the belt (30) forms a shallow angle relative to the charge receptor (10), downstream of the nip, the belt (30) forms a steep angle relative to the charge receptor (10). This configuration enables self-stripping of the sheet from the transfer belt at the exit of the nip.

Abstract: A document handler (20) for presenting documents to the platen (23) of a copier (10) for copying with a document transport system (32) having document-transport belts (35) movable under a substantially-planar background surface (33a) overlying the platen, and a suction system (33) for applying a partial suction to a document sheet being transported by the movable belts over the platen; with a clamping and unclamping system for moving the background surface against the platen to flatten the belts and a document thereon against the platen for copying. During unclamping, the surface lifts slightly away from the platen, while the document is retained on the belts by suction, by first lifting one edge of the surface 33a up away from the platen substantially before the opposite side, and then subsequently lifting the opposite side, to generate a controlled air flow across the face of the document to retain it on the belts, and moving the belts when the surface is lifted away from the platen. During clamping the one side of the surface 33a moves towards the platen, beginning slightly before the opposite side, to generate a controlled expulsion of air. The disclosed system has two pairs of commonly rotatably driven cams (60, 60a, 62, 62a) with different cam rise times connected to lift the one side of the clamping surface with a motion different from that of the opposite side. The cams can first lift the one side about 2.5 mm, while the opposite side remains in contact with the platen, then lift the opposite side about 0.8 mm, and then the clamping surface can be leveled by lifting the opposite side to about 1.75 mm while the one side is dropped to about 1.75 mm.

Abstract: A device and method of enhancing contact between a photoconductive member of a electrophotographic printing machine and the paper to which an electrostatic latent image is to be transferred uses an array of wiper blade segments mounted on a common shaft. Each segment is attached to the shaft for limited rotational movement on the shaft in opposition to a torsion spring. The torsion spring biases the blade segment towards the paper. Some of the blade segments are operatively associated with a stop mechanism to control the length of the wiper blade array in accordance with the size of the paper being processed. The stop mechanism prevents movement of the blade segment into engagement with the paper by restraining movement of the segment against its torsion spring.
