摘要： A catch tray for a copier/printer holds and stacks copies of a wide variety of sizes exiting a copier/printer without operator involvement. The copies are allowed to fall into a funnel type baffling device with flexible friction paddles that drive the incoming copies into the catch tray and holds them in place while simultaneously allowing a major portion of each copy sheet to flip and hang down over a curved portion of the outer wall of the catch tray.

摘要： A development system for a reproduction machine includes a pair of augers which mix and transfer the developer mixture to a magnetic roll brush system. The supply auger is positioned in a horizontal plane; the second return auger is at an angle to the first auger. The first auger transports developer material in one direction mixing the developer material and dispensing developer material along its length by gravity to the magnetic brush roll sump. A developer material transport opening at one end allows developer material to be gravity fed to the adjacent end of the inclined auger which carries the developer material uphill. The developer material is transferred at the other end by gravity feed back to the first auger.

摘要： A device that addresses the problem of substrate distortion created by a fuser nip being transmitted back to a transfer nip includes a post transfer corrugator that introduces a non-image side protrusion in the substrate path between the transfer zone and the fuser zone. The post transfer corrugator forces the substrate to flatten out any distortion caused by the fuser/nip and prevents this distortion from entering the transfer zone. The corrugator also supports the substrate so as to increase the wrap angle of the substrate around an electrostatic member.

摘要： The invention is directed towards a web cleaning system which is used in a xerographic reproduction machine to simultaneously clean the surface of a photoreceptor and of a fuser roll. The fuser roll is of the type having an elastomer coating requiring application of a silicone oil. The web cleaning system performs a third function by applying a predetermined amount of oil from an oil donor web onto the side of the web which cleans the fuser roll surface. In a further aspect of the invention, the web cleaning components are mounted in a customer replaceable unit (CRU) for convenient removal.

摘要： A low cost, paper feeder for large copy sheets includes a media chamber mounted to support copy sheets in a substantially vertical plane. A two-position, T-shaped feeder mechanism including a pair of one-way clutch controlled feed rolls is slidably mounted on a rail for contacting the media. A foot pedal is connected to the feeder mechanism such that when movement of the foot pedal is initiated, the feeder mechanism is moved in a first direction to a position contacting the copy sheets and with continued movement of the foot pedal, a top sheet of the copy sheets is moved by the feeder mechanism out of the tray in a second direction a predetermined amount to a copier wait station, and with return of the foot pedal to its initial position, the feed mechanism is caused to retract from the surface copy sheets in a third direction to its initial position.

摘要： A device for transferring electrical charge from an electrically conductive element to a rotating element is provided. The device has a body including a pultruded composite member having a multiplicity of electrically conductive fibers provided with a polymer matrix. The plurality of conductive fibers is oriented within the polymer matrix in a longitudinal direction of the pultruded composite member. The fibers each extend in a substantially parallel direction, parallel to a first axis. The body includes a first contact area. The body defines an aperture therein. The body has a second contact area on the periphery of the aperture spaced from the first contact area and a support. The support is secured to the body for supporting the body. The first contact area is for contact with the conductive element and the second contact area is for contact with the rotating element. The fibrillated portion is coincident with at least one of the first contact area or said second contact area.

摘要： A copier with an anamorphic magnification imaging system is provided with improvements which enable increased resolution of exposed line images at a photoreceptor. The improvement relates to reducing the effective imaging aperture through which the images is projected onto the surface of a photoreceptor. In one embodiment, a gradient index lens array which transmits light reflected from illuminated scan strip on a document platen is provided with two blockers attached to opposite sides of the lens array. Each blocker element has a blocking end which projects into the optical path and blocks a portion of the light that would otherwise be transmitted along the optical path. The effect of the two blockers is to form an effective imaging aperture having a width less than 1mm, in the preferred embodiment about 0.4mm. This narrow imaging width enables a high resolution output image. Increased illumination requirements are met, in another embodiment, by using a faster lens to increase exposure and modifying the lens by adding an extra pitch to increase the total conjugate which would otherwise limited by using the faster lens.

摘要： A simple, low cost, hand operated paper feeder includes a media chamber mounted at an acute angle with respect to a horizontal plane that allows media to exit the chamber through a membrane. A two-position, T-shaped actuator including a pair of non-rotating rolls is slidably mounted on a rail for contacting the media. A rod is connected to the actuator such that when movement of the rod is initiated in a first direction, the actuator is moved to a position contacting the media and with continued movement of the rod, a top sheet of the media is moved a predetermined amount through the membrane, and with return of the rod in a second direction to its initial position, the actuator is caused to retract from the media surface to its initial position.

摘要： A toner cartridge is modified so as to improve the dispensing of toner through discharge ports extending longitudinally along the cartridge. A flexible flap member is secured external to the cylinder and overlies the ports so as to prevent toner from exiting the ports except along the preferred dispense zone, e.g., from the 4 o'clock to the 8 o'clock position.
