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 bel t, and a torque assist drive that applies a torque assist force T d 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, th e torque assist force T d facilitates accurate positioning of the belt (e.g., latent image registrations in a color imaging process employing multiple imaging processi ng stations) by reducing slippage between the drive roller and the belt that ma y be encountered due to belt wear, toner contamination and/or other debris.

Abstract: A single pass, multi-color electrophotographic printing machine architecture uses a vertically oriented photoconductive belt. Transfer of the toner powder images occur at the lowermost portion of the photoconductive belt. The photoconductive belt is elliptically shaped, having a major and a minor axis. N image recording stations are positioned adjacent an exterior surface of the photoconductive belt on one side of the major axis thereof. N-1 image recording stations are positioned adjacent the exterior surface of the photoconductive belt on the other side of the major axis thereof. The image recording stations record electrostatic latent images on the photoconductive belt. This architecture optimizes image registration while minimizing the overall height of the printing machine.

Abstract: A belt drive module and a corresponding method includes or employs a belt (10) that moves along a path, at least one support roller (12) or other structure that supports the belt as it moves along the path, a drive roller (11) that effects movement of the belt along the path, a tension roller (74) 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 (66), 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.

Abstract: The present invention relates to a color printer which forms multiple latent images on the surface of a belt type photoreceptor in a single pass. The invention enables the placement of imaging stations (29,30,32,34) on both a tensioned and non-tensioned side of the belt (36) On the non-tensioned, an asynchronous line at a time printer such as an LED print bar (34A) is used to form the latent image in response to video data signals. On the tensioned side of the belt, either synchronous type imagers (29A,30A,32A), such as laser ROSs or asynchronous imagers such as LED print bars may be located to form the latent image. The leading edges of each image frame are registered according to known methods. Each scan line within an image frame is registered by comparing the belt speed beneath each of the imagers and generating a correction signal to the asynchronous print bar. Since the print bar operates asynchronously, it is possible to vary the pulsed line write time so as to register each of the scan lines formed by the print bar with the scan line being formed by the imagers at the tensioned side of the belt.

Abstract: An encoder interface for interfacing an encoder having a first part (104) defining a first axis to a structure having a second part (106) defining a second axis substantially parallel to the first axis includes a portion for translating the first part (104) with respect to the second part (106) in a direction transverse to the first axis and a portion for rigidly rotationally stabilizing the first part (104) with respect to the second part (106) against a rotation of the first part (104) about the first axis induced by a translation of the first part (104) with respect to the second part (106) in the direction transverse to the first axis. A method for interfacing an encoder having a first part (104) defining a first axis with a structure having a second part (106) defining a second axis substantially parallel to the first axis includes the steps of translating the first part (104) with respect to the second part (106) in a direction transverse to the first axis and rigidly rotationally stabilizing the first part (104) with respect to the second part (106) against a rotation of the first part (104) about the first axis induced by a translation of the first part (104) with respect to the second part (106) in the direction transverse to the first axis.
