摘要： An imaging module mounting structure is used for mounting an imaging module to an imaging device that has a support member and a rotatable photoreceptor. The imaging module includes an imaging bar and a corona generating device. The imaging module mounting structure includes a pair of pivot block devices which are pivotably connected to the support member in a spaced apart relationship. The imaging bar and the corona generating device are secured to each one of the pair of pivot block devices. Each pivot block device includes a cam follower element. The pair of pivot block devices are operative to flex independently of one another while the photoreceptor rotates so that the respective cam follower elements remain in contact with the rotating photoreceptor to compensate for photoreceptor run out. A method for practicing the present invention is also described.

摘要： A charge roller displacement mechanism prevents the build up of a sharply defined circumferential ring of contaminants on the surface of a charge roller in an electrophotographic printing system, thereby reducing the severity of the print defect caused by the contaminants. By cyclically laterally displacing the charge roller parallel to the longitudinal axis of a photoconductor drum as the photoconductor drum rotates, contaminants which reach the surface of the charge roller will not form a sharply defined circumferential ring that interferes with the uniform charging of a photoconductor drum charged by the charge roller. The charge roller displacement mechanism includes a first gear that engages the gear used to rotate paddles in a waste hopper of an electrophotographic printer cartridge. A second gear engages the first gear to provide a reduction of approximately 400 to 1. The charge roller is forced against a face of the second gear by a spring or, alternatively, by angling the longitudinal axis of the charge roller with respect to the longitudinal axis of the photoconductor drum. The face of the second gear contacting the charge roller includes a lobe. As the second gear rotates, the charge roller is laterally displaced across the surface of the photoconductor drum. The lobe is shaped so that one rotation of the second gear corresponds to one cycle of displacement of the charge roller.

摘要： The door (3) of a laser printer (1) is pivoted to the frame (1c) of the printer by a pin (21) of hinge (19). When the door is shut, link (33) is rotatably connected to the hinge at a location above the pin. Link 33 has an elongated slot (33a) at its end opposite the hinge in which a pin (51) does not encounter the edge of the slot when the door is closed. Spring (31) therefore rotates U shaped link 11 around its pivot point (15) to the frame to bring charge roller (9) into contact with photoconductor drum (5). When the door is manually opened, spring 31 provides an upward force, link 33 is moved forward where the slot engages pin 51, which pivots both link 13 and door 3 upward. Force of the charge roller against the drum is by the spring as the only active element, thereby providing a controlled force.
