摘要： A sheet feed cassette adapted to be installed within a sheet feed unit of an image forming apparatus such as, for example, a copier as a printer. The cassette includes a frame including at least a side frame and a bottom frame. A bottom plate is provided above the bottom frame including collapsible guide walls for positioning four separate stacks of sheets within the cassette on the plate. Each of the walls are adapted to collapse thereby allowing each of the four stacks of sheets individually to be moved within the cassette to be in contiguous relation to a feeder unit for feeding individual sheets from a single stack of sheets that is positioned within the cassette into the apparatus. A feeding device moves each of the four stacks from different positions within the cassette to the feeder unit so that individual sheets can be fed to the apparatus for each of the four stacks.

摘要： A motion-defect-free assembly and a method of minimizing cleaning apparatus induced motion quality disturbances in a moving belt photoreceptor of a toner image reproduction machine are provided. The assembly for practicing the method includes at least one resilient member located to each side of the moving belt photoreceptor at a desired belt cleaning station along a path of movement of the belt photoreceptor, and a cleaning apparatus that is mounted at the cleaning station and that includes at least one separately moveable cleaning member. The cleaning apparatus also includes a moveable frame having frame locating members, and the at least one separately moveable cleaning member. The motion-defect-free assembly also includes a drive and control system for first moving the moveable frame into contact with each of the locating members and for then separately moving, relative to the moveable frame, the at least one separately moveable cleaning member into contact and cleaning engagement with the moving belt photoreceptor, thereby minimizing cleaning apparatus induced motion quality disturbances in the moving belt photoreceptor.

摘要： An apparatus and method for correcting top edge sheet misregistration using a sensor array. An array sensor is placed in the paper path prior to transfer. A signal is generated indicating the position of the sheet. As a function of the signal the print controller causes the image to be exposed and developed on the photoreceptor in alignment with the sheet position. The aligned image is then transferred to the sheet.

摘要： A gateless rocker inverter for reversing the lead and trail edges of a sheet includes two idler roll and drive roll nip pairs with the drive rolls continuously rotating in opposite directions. The idler rolls are attached to two ends of a coupler of a four-bar linkage which opens and closes the nips in sequence, first to drive the sheet forward and subsequently to drive the sheet in a reverse direction out of the inverter for duplexing purposes.

摘要： A transfer system including a contact member for applying pressure against a copy substrate to create uniform contact between the copy substrate and a developed image on an imaging member. The transfer system includes a flexible transfer assist blade and a rotatable cam shaft having a lobe for deflecting the transfer assist blade into contact with the copy substrate. Alternatively, the transfer assist blade may include multiple segments and the rotatable cam shaft may include a plurality of lobes, each having a lengthwise dimension corresponding to predetermined segments of the blade for providing contact across a dimension corresponding to that of the copy substrate. The system further includes a stepper motor for rotating the cam to predetermined angular positions to create an abutting relationship between the lobe and the transfer assit blade for deflecting selected segments of the blade toward the copy substrate. The transfer assist blade presses the copy sheet into contact with at least the developed image on the photoconductive surface to substantially eliminate any spaces or gaps between the copy sheet and the developed image during transfer of the developed image from the photoconductive surface to the copy sheet.

摘要： A non-contact, transmissive energy sensor is utilized for determining the thickness of paper sheets in a feed path. The sensor includes an energy emitting source and an energy detector, the output of the energy detecting source being proportional to the amount of energy received by the energy detector. The signal output level of the detector is utilized in a model to determine the basis weight of paper in the detecting zone of the detector. Heuristic sampling techniques can be utilized to reduce or eliminate the effects of images printed on the paper and flutter of the paper as it moves. An automatic calibration routine utilizing boundary coefficients is used to calibrate the paper basis weight detection system. The paper basis weight determination is utilized to control subsequent operations to which the paper sheet is subjected in order to optimize image quality and sheet handling, and to control finishing operations.
