    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： 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： 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： An improved coronode assembly includes pin guards that are positioned closely spaced from and extending above a coronode in order to provide protection for a user reaching past the coronode to remove a sheet jam, and prevent coronode damage when the coronode is handled during servicing by a field service technician. The closeness of the pin guards to the coronode also serves to produce a more uniform field.
