A high capacity copy sheet supplying system for reproduction apparatus, in which a large and heavy stack of copy sheets may be much more easily and accurately loaded therein, by a sheet supplying container insertable into the sheet supply input. This container has sheet stack confining side walls, a bottom wall with plural spaced apertures, and a false bottom tray insert loosely overlying that bottom wall on which the stack of copy sheets is supported. Plural lift rods are operatively connecting with an elevator system to provide movement of the lift rods up through the apertures in the bottom wall of the sheet supplying container, to engage and lift the false bottom tray and the large and heavy stack of copy sheets supported thereon by engagement of the ends of the lift rods, so as to lift up the large stack of copy sheets from within the sheet supplying container into engagement with a fixed position sheet feeder, and then to automatically maintain feeding of sheets from the top of the stack by maintaining with the elevator system the level of the top of the stack until the sheets are depleted by the sheet feeder. The same container can be used for an output stacker. It also may have a contents viewing window.

A substrate feeding system, and printers that use such feeding systems, that includes a feed roll and a retard roll that form a nip, a nudger roll for advancing a substrate from a substrate stack toward the nip, and an entrance guide between the nudger roll and the nip. The entrance guide has a contact surface that forms an angle of more than 100.degree. with the direction of motion of the substrate. The entrance guide further including a top section over which the substrate moves as it advances into the nip. The entrance guide is beneficially pivotally mounted such that when a retard roll is removed the entrance guide pivots out of the way, and such that when a retard roll is in place the entrance guide moves into position.

A replacement drive roll having an integral bearing for easy replacement and universal usage in a printing machine. The roll member has a bearing having a nonround outer race for retention in a frame member and a nonround inner race for engagement with a driveshaft on one end. The opposite end has a locking member for preventing axial movement along the shaft. The roll assembly has elastomer bands stretched around the outer circumference to form the drive surface of the roll. The roll unit is easily replaced and can be used in numerous locations thereby reducing parts inventory requirements.

An enlarged buckle chamber is positioned within an easily accessible, copy sheet transport path and used to compile sheets during fault cycle down in copiers/printers whenever sheets are prevented from reaching the output in sequence by jammed sheets. The user can then clear most jams by accessing the jam area plus the 'easy to reach' area where internally purged sheet are gathered, thereby avoiding having paper distributed all over the paper path.

A sheet feeding system for an imaging system with a sheet input tray into which sheets are loaded onto the upper surface to be fed downstream, with a sheet sensing system for automatically providing different electrical control signals in response to different sheet sizes and different orientations of the sheets loaded into the tray, with sensor actuators projecting into the tray at different preset positions, each actuator being movably mounted to normally project upwardly through an aperture in the tray until operatively engaged by the sheets loaded onto the sheet input tray extending over the preset position of the actuator. Each actuator has an operative shape tapering upwardly from a relatively large base to a relatively small tip to provide laterally angled sheet engagement surfaces on at least three lateral sides thereof, preferably pyramid shaped. These surfaces are sufficiently angled to push down the actuator and prevent jamming or damage to the actuator from stocks of sheets being manually inserted into the sheet input tray from different angles and directions, especially, laterally.

An idler system that is both self-centering and self-aligning with a drive roll. The idler assembly consists of a pair of rolls connected by a shaft, the shaft being supported in a housing. The housing is retained by a resilient spring member which member allows the axis of rotation of the idler rolls to pivot in more than one plane simultaneously. This pivoting causes the axis of rotation of the idler assembly to align parallel with the drive roll axis. The single spring also provides an even loading of the normal force across the width of the drive nip. As a result of the alignment and even loading, skewing of a sheet is prevented as it is driven through the nip formed by the drive roll and the idler roll. The resilient spring mounting also allows for easy replaceability of the idler assembly and the housing is easily locatable between tabs formed in the frame of the machine for mounting the idler assembly therein. The housing provides a guide from the mounting frame into the nip and from the nip into the downstream paper path for increased capacity to handle curled and/or damaged cut sheet media.

Self-aligning, low jam rate idler assembly

A duplex path loop having a acceleration nip cooperating with a belt transport and retime nip to allow duplexing of sheets while minimizing skipped pitches on the photoreceptor. As each sheet to be duplex printed is removed from the process path after first side imaging it is accelerated to create a gap between it and subsequent sheets. The sheet is then stalled or slowed in a retime nip, while subsequent sheets to be duplexed are simultaneously driven by the same transport, the first mentioned sheet being reinserted into the process path at the proper time for receiving the second side image before the arrival of the second sheet at the retime nip. Subsequent duplex sheets are handled in the same manner so that duplex copies are interleaved or otherwise reinserted into the process path with first side copies so that skipped pitches on the photoreceptor are minimized.

A multifunction blower in which a common housing is employed to both increase and decrease the pressure of incoming air in separate chambers thereof. The increase and decrease in air pressure is adjustable by changing the impellers of the pressure and vacuum assemblies used therein.

Universal blower

A mounting which supports a bearing in a machine frame. The mounting is molded with the bearing being molded integrally therewith in an aperture therein. The outer race of the bearing is in molded non-rotative engagement with the mounting. The mounting has a plurality of mounting supports. At least one of the mounting supports is adapted to be received by the frame.
