    Abstract: 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.

    Abstract: 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.

    Abstract: A belt drive module and a corresponding method includes or employs a belt that moves along a path, at least one support roller or other structure that supports the belt as it moves along the path, a drive roller that effects movement of the belt along the path, a tension roller that applies a tension force to the belt in order to maintain engagement of the belt with the drive and/or support rollers, at least one processing station (e.g., an image processing station) disposed along the path that performs a process relative to a predetermined position of the belt, and a torque assist drive that applies a torque assist force Td at a location between the drive roller and the tension roller. Torque assist may be provided by a current limited DC motor or by a constant torque friction clutch applied to a roller, e.g., a stripper roller of an electrophotographic imaging system. Advantageously, the torque assist force Td facilitates accurate positioning of the belt (e.g., latent image registrations in a color imaging process employing multiple imaging processing stations) by reducing slippage between the drive roller and the belt that may be encountered due to belt wear, toner contamination and/or other debris.
