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 multimode document handling apparatus and reproducing apparatus containing same are described wherein the document handling apparatus comprises an upper frame portion pivotally mounted along its rear edge to a lower base frame portion to provide open and closed positions of the upper frame relative to the lower frame. The lower frame contains a substantially horizontal imaging platen and document transport defining a generally horizontal document transport path. The upper portion contains a vertically inclined document loading chute the lower exit portion of which intersects the generally horizontal document transport path. The document loading chute includes a gate to permit loading of successive copies in the chute while preventing it from being fed as the preceding document is being copied. The device makes single copies by inserting a document into the chute and multiple copies by reversing the direction of the transport rolls to drive the document after having once been copied back across the platen in the horizontal path past the exit portion of the chute to be transported forward again across the imaging platen. At the same time in this multicopy mode the chute can be used as a wait station for insertion of the next document to be copied. The chute is also used as a wait station during the stream feeding of successive documents. To copy pages of a book, the upper frame portion is pivoted up and the book is placed on the transport rolls which transport it across the imaging platen.

Abstract: PROBLEM TO BE SOLVED: To provide a photoconductive member which optimizes the length of a photoconductive belt and utilizes the length of the belt to the maximum to print a copy. SOLUTION: The photoconductive member 10 for use in a single pass multi-color printing machine includes an inter-seam zone 92 having a physical seam. The inter seam zone includes one (89) of a plurality of image-on-image registration marks. A plurality of interdocument zones 90 and 84 is also included on the photoconductive member wherein process control marks are formed. While the inter-seam zone is used for monitoring image-to-image registration, the process control marks are monitored to adjust the timing of the printing machine so that copy media synchronizes with an asynchronous placement of the images on the photoconductive member 10.

Abstract: PROBLEM TO BE SOLVED: To provide an apparatus or a method for controlling and/or adjusting the lateral position of one or more belts in a printing system in order to avoid processing interruptions or delays, or the like. SOLUTION: The belt is generally moveable in a process flow direction within the printing system, wherein a lateral direction extends substantially along the belt and substantially perpendicular to the process flow direction. The apparatus includes: a roller assembly for engaging at least a portion of the belt and extending laterally across the belt; a pair of laterally spaced support arms each rotatably supporting opposed ends of the roller assembly, and being pivotally coupled to the printing system for movement about a pivot axis extending substantially in the lateral direction; and an actuating assembly for pivotally moving at least one support arm about the pivot axis. The pivotal movement pivots one support arm relative to the other. COPYRIGHT: (C)2011,JPO&INPIT

Abstract: PROBLEM TO BE SOLVED: To restrain the slip of a belt at the time of driving the belt. SOLUTION: A belt driving module and a corresponding method include or adopt the belt moving along a path, at least one supporting roller or another structural body to support the belt when the belt is moved along the path, a driving roller to move the belt along the path, a tension roller to apply tensile force to the belt in order to maintain the coupling of the belt with the driving roller and/or the supporting roller, at least one processing station (for example, image processing station) arranged along the path in order to perform a process related to the specified position of the belt, and a torque supporting and driving part to apply torque supporting force Td at a position between the driving roller and the tension roller. The torque supporting force Td makes the exact positioning of the belt easy by reducing the slip between the driving roller and the belt.

Abstract: PROBLEM TO BE SOLVED: To provide a photoreceiving belt tension system by which the tension of a belt being in a belt steering operation is reduced and also excellent color positioning is attained. SOLUTION: A non-elastic tension mechanism setting and controlling a tension roll system with a photoreceiving body belt module acts on at least one of a pair of rollers about the periphery of which the photoreceiving body belt is entrained thereby keeping practically uniform tension even for the various total length of the belt.
