    摘要: In a printing system capable of printing and outputting collated sets of plural duplex copy sheets from input job sets of plural page images using a trayless duplexing buffer loop path of a known normal plural copy sheet length for recirculating the copy sheets imaged on one side back to be imaged on their opposite sides; operating in a continuous loop burst-interleave mode, using a variable speed duplex drive, for driving at least a major portion of the duplexing path sheet feeders at at least two different sheet feeding speeds so as to initially feed a limited number of the sheets to be printed on one side, less than the duplexing path length, at full rate without skips, to the duplexing path to be selectively partially fed therein at substantially higher than normal velocities, and to variably selectively reduce the velocity of the duplexing path with the initial sheets therein, to generate sheet interleaving spaces between these duplexing path sheets, so that they may be interleaved for their second side printing with subsequent first side prints until the final sheets of the job, which are also fed through the duplexing path at higher than normal speeds for different distances so as to close up interleaving spaces. This increases the duplex copying rate of the printing system by reducing or eliminating skipped pitches without requiring an increase in the given or normal printing rate.

    摘要: A copying and or printing apparatus including a duplex feeder for feeding sheets having had page image information copied/printed on one side thereof, back to a copying/printing station for transferring page image information to the other side thereof. The duplex feeder includes a buffer tray that can be positioned above and slightly upstream of a feeder tray. The buffer tray stores copy sheets exceeding the maximum capacity of the feeder tray such that the copier/printer can process a greater number of duplex copies in a single run.

    摘要: An apparatus for individually feeding sheets from a stack of sheets, comprises a tray for supporting a stack of sheets to be fed therefrom. A sheet feeder is provided for individually capturing a top sheet from the stack and for conveying the top sheet out of the tray. A solenoid-activated sheet hold down device is provided which includes a portion being cyclically movable toward and away from the stack for exerting a force on a next top sheet beneath the top sheet to prevent the next top sheet from being forwarded out of the tray while the top sheet is being forwarded.

    摘要: An apparatus for advancing at least two different types of substrates from a moving surface to a fusing station is disclosed. A constant speed transport positioned to receive the substrate from the moving surface advances the substrate to the fusing station. An air moving device moves air such that air pressure induces a drive force on the substrate on the transport. A sensor generates a first signal when the substrate is of a first type and generates a second signal when the substrate is of a second type. The air moving device induces a first drive force when the sensor generates the first signal and induces a second drive force when the sensor generates the second signal.

    摘要: An apparatus in which sheet basis weight is determined as a function of a change in angular velocity of a roller defining a nip through which the sheet passes. The sheet basis weight is calculated in response to the change in angular velocity of the roll before and after the sheet enters the nip. In an electrophotographic printing machine, the change in angular velocity of the fuser roll or pressure roll may be used to calculate the sheet basis weight.

    摘要: An apparatus to bilaterally register and deskew sheets in an electrophotographic printing machine by driving the sheet against a pair of stalled drive rolls and then activating the drive rolls when the sheet is deskewed. The drive rolls are then laterally translated while the sheet is within the nips of the drive rolls. The proper side registration position of the sheet is sensed and stored and the sheet is brought to that proper registration position. Once the sheet has passed through the drive rolls, the rolls return to the center of the paper path to receive subsequent sheets. A stepper motor is used to translate the roll pairs in a lateral direction and the pulse counts are utilized to store the side registration and sheet acquisition positions thereby eliminating the need for a home position sensor or switch.
