A drive roll/idler roll nip release mechanism utilizes the motor used for the drive nip, coupled with one-way clutches, to power the nip release as a sheet is handed off to a downstream nip. A drive shaft is coupled to a first one-way clutch in one direction and an idler cam shaft is coupled to a second one-way clutch in the opposite direction. This allows the idler cam shaft to be driven only when the motor is reversed, and the drive shaft to be driven only when the motor is moving forward. The one-way clutch on the drive shaft allows the drive wheels to freewheel when the motor is reversed in order to engage the nip release. Thus, the nip release is activated while the drive nip continues to rotate in the direction of sheet motion.

A printing apparatus comprises a plurality of substantially identical modules forming a common sheet path. Each module includes an image receptor, a supply of marking material of a predetermined type, and a marking engine for creating an image of marking material on the sheet. Within each module a transport receives a sheet, moves the sheet to receive the image from the marking engine, and makes the sheet available for printing by a subsequent module in the sheet path. A sheet sensing system within each module detects a position of the sheet and uses that information to adjust the position of the image to be transferred to the sheet.

An intergrated printing system is provided that includes at least two substantially horizontially aligned printing modules including an entrance media path and an exit media path; and at least one interface media transport including at least two substantially horizontal media transport paths, wherein the horizontal media transport paths are positioned vertically relative to each other to provide upper and lower horizontal media transport paths and the horizontal media transport paths transport paths are positioned vertically relative to each other to provide upper and lower horizontal media transport paths and the horizontal media transport paths transport media to the horizontally aligned printing module. The integrated printing system also provides for a horizontal media transport path to transport media to the horizontally aligned printing module in a direction that passes the exit path of one of the horizontally aligned printing modules before passing the entrance media path of the other printing module.

A system for automatically releasing selected plural sheet feeding nip sets spaced along a print media sheet feeding path of a printer, wherein the idler rollers are rotatably mounted on common idler shafts and a selectable partial rotation system driven by a single low cost motor is flexibly connected to those plural idler shafts to partially rotate eccentric lift cams on each idler shaft into the underlying surface as to lift the idler shaft and thereby move the idler rollers away from their normally mating sheet feed rollers to release all the sheet feeding nips, enabling sheet deskew, inversion, acceleration, deceleration, or sheet jam clearance in that selected area of the sheet feeding path.

In a lateral sheet shifting system, wherein sheets are fed from a sheet input to a sheet output with controlled shifting transversely of the process direction, there is a pivotal arcuate sheet path defining baffle unit providing an arcuate sheet-feeding path between the input and output. This arcuate baffle unit is mounted for pivotal angular movement laterally of the process direction by a controllable automatic variable angle pivoting system to form a variable sheet spiraling path therein. The arcuate baffle unit may be generally "S" or "U" shaped, and may be defined by, or consist solely of, opposing relatively closely spaced similarly arcuate baffles, such as at least two operatively connecting but oppositely facing generally quarter-cylindrical sections which can provide sheet side shifting without introducing any sheet skewing. The sheets in the baffle unit need not be engaged by any sheet feeding rollers therein, and the sheet input and output can be simple conventional fixed rollers on fixed axes. The sheet input and output may be co-linear but at different vertical levels. This entire sheet side shifting system can be a small, short paper path, modular unit provided internally or externally of a reproduction apparatus, such as interconnecting to a finisher with a laterally different paper path.

A method for a sheet handling system where a controller communicates with a mailbox bin subsystem having a plurality of print receiving bins is provided. The plurality of bins are grouped into a first print receiving bin set, a second print receiving bin set and a third print receiving bin set with the first print receiving bin set including one or more print receiving bins, the second print receiving bin set including one or more print receiving bins and the third print receiving bin set including one or more print receiving bins. A first bin access designator is assigned to each print receiving bin of the first print receiving bin set, a second bin access designator is assigned to each print receiving bin in the second print receiving bin set and a third bin access designator is assigned to each print receiving bin in the third print receiving bin set--the first, second and third bin access designators correspond respectively with a first user class type, a second user class type and a third user class type. A request is communicated to and read by the controller. In response to such reading, the one or more produced prints are delivered to one or more print receiving bins in one or more of the first, second and third print receiving bin sets.

In a sheet handling system with a supporting frame, a sheets compiling tray, and a sheets ejection system including an drive shaft with plural sheet drive rollers and a pivotal mounting system for pivoting the drive shaft between a first position for sheets ejection and a raised second position, the pivotal mounting system provides vertical freedom of movement of at least one end of the shaft in the first position to provide a self-leveling more uniform sheet engagement force, yet also provides a positive accurately centered constrained position of the shaft in the second position. The illustrated pivotal mounting system includes a pivot pin vertically movable within a mounting slot in the supporting frame in the first position and spaced apart limited length mounting slots providing end stops engaging mounting pins in the second position to automatically center the pivot pin.

A plural function sheet interconnect module for serially connecting plural multiple bins printed sheets job separating units, such as mailbox modules, with the output of a printer for feeding printed sheets jobs into selected bins. The printer also has a alternate variably occurring output of purge sheets designated for purging, which purge sheets are variably intermixed with the printed sheets jobs. The interconnect module has a sheet bypass transport for feeding the sheets on from one mailbox unit on to another. The interconnect module also has an integral purge tray for collecting the purge sheets and providing for their removal. The interconnect module further has a selectable shared sheet gating system for gating the printed sheets jobs into the sheet bypass transport and gating the purge sheets into the integral purge tray. The integral purge tray underlies the sheet bypass transport and is pivotably openable for the removal of purge sheets therefrom.
摘要:
In a sheet stacking system for stacking plural sheets from a printed sheets output path into at least one sheet stacking tray, including a stack height sensor for detecting the height of the stack of sheets in the tray and controlling a stacking control system; the stack height sensor has an elongated maximum stack height sensing bar, and a sensing bar movement system for intermittently moving the maximum stack height sensing bar into the tray in an operative measurement position on top of the stack of sheets in the tray at a position transversely of the sheet entrance path, with a normal force pressing downwardly against the top of the stack. The stack height sensing bar in this position extends across the top of the stack at the height of the highest level of any portion of the stack, in particular, overlying the sets stapling area. A sensing system is actuated by the height of the stack height sensing bar in this measurement position to provide signals to the stacking control system, which provides a control signal when the maximum stack height in the sheet entrance path to said sheet stacking tray reaches a height which is preset below the height which would obstruct the sheet entrance path. This sensor system can move, to measure several bins, and can also provide a sheet knockdown function.
