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

    摘要： An apparatus and method for automatically adjusting the timing of a transfer assist blade in an electrostatographic imaging system. The apparatus and method operate by partially toning an area of the photoreceptor and then actuating the transfer assist blade such that it smears at least a portion of the partially toned area. Using an electronic toner area cover sensor system, the amount of smearing can be determined, From this, the timing of engagement of the transfer assist blade with the photoreceptor can be determined and, if necessary, adjusted.

    摘要： 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.

    摘要： In a fuser for xerographic printing, stripper fingers remove the print sheet from a fuser roll. The stripper finger having a tip for stripping a lead edge of a sheet from the fuser roll. A roller assembly, positioned adjacent to the stripper finger; for engaging the lead edge of a sheet and lifting the sheet from further contact with the tip after the tip of the stripper finger strips the lead edge of the sheet from the fuser roll. The roller assemlby is removably mounted by using a snap-on mounting structure.

    摘要： An electrophotographic printing apparatus includes a housing, a photoreceptor module located inside the housing that includes a photoreceptor, a raster output system located inside the housing for projecting an electrostatic image onto the photoreceptor, a charging station, a developer station, a transfer station, a pre-fuser transport, and a fusing station. The module may be removed from an operating position inside the housing. The transfer station is connected to the pre-fuser transport so that they are constrained to move as one unit when the photoreceptor module is in its operating position inside the housing but are disconnected when the photoreceptor module is removed from its operating position inside the housing. The transfer module may be mounted so as to be constrained by a pre-fuser transport.

    摘要： A guide system for xerographic printing apparatus introduces paper bearing an unfixed image and having a broad range of basis weights into a fuser nip from a prefuser transport without causing image smear. An entrance baffle is positioned in the path of the paper advancing toward the fuser nip for engagement by the paper's leading edge. The entrance baffle is hinged at its mounting end for swinging movement between a maximal and minimal positions as defined by stop members and is biased into engagement with the minimal stop member. The magnitude of the bias is chosen such that as the lightest basis weight paper engages the entrance baffle, it bends around its free end and is guided into the fuser nip, and such that as the heaviest paper engages the entrance baffle, it forces the entrance baffle toward engagement with the second stop member and itself is guided into the fuser nip.
