A system and method are provided for improving stack integrity for a set of image receiving media substrates at an output of a compiler in an image forming device positioning a plurality of pairs of rotating shelf structures in a vicinity of an exit/ejection port of an image receiving media processing or post-processing unit. The plurality of pairs of rotating shelf structures cycle between a first (support) position and a substantially orthogonal second (drop) position with respect to a rotating axis for the rotating shelf structures. Each of the rotating shelf structures has a uniquely-portioned top surface that includes a substantially-parallel top (supporting) portion and a ramped lead-in portion facing the exit/ejection port from the image receiving media processing or post-processing unit in an effort to reduce any image receiving media substrate 'stubbing' against a first of the plurality of pairs of rotating shelf structures in a process direction.

Systems and methods for implementing unique stack registration using rotating shelf structures for set compiling in image forming devices

A system and method are provided for improving stack integrity for image receiving media substrates in a compiler tray in an image forming device by supplementing the structure of the compiler tray with a pair of auger components configured with a bottom surface that, in conjunction with a stepped support structure in the compiler tray, applies a mechanical leveling force to reduce or otherwise eliminate detrimental effects associated with substrate curl or uneven set build-up in the compiler tray. The vertical compiler components provide an accommodation for localized thickness build-up in compiled image receiving media substrates by one or more processing or post-processing steps. The auger components provide a mechanical pressing force that is intended to level a top surface of the compiled substrates with the configuration of the compiler tray providing the relief area necessary for the accommodation.

Systems and methods for implementing a unique variable stacking surface for set compiling in image forming devices

A system and method are provided improving stack integrity for a set of image receiving media substrates at an output of a compiler in an image forming device by supplementing a compiler shelf with a pair of augers having a unique planar lead-in for a top surface of the augers. The vertical compiler components reduce a 'stepped' configuration of conventional compiler systems to keep a bottom sheet substantially 'flat' thereby reducing a tendency for the bottom sheet to disadvantageously shift during in-set alignment processing. The large flat surface at the top of the augers effectively extends the plane of the lead edge shelf. A larger contact area with the sheets/sets of image receiving media substrates, along with the flatter shape of the sets, results in a more stable stack with a lesser tendency of individual sheets to migrate away from a registration edge.

A system that avoids any stopping or reversing of the web direction in a continuous feed printer, instead maintaining consistent process speed, only requiring a slowing and speeding up of the web to cycle through the PR belt seam. This is done by forming a web loop and then immediately flattening the loop after passage of the seam through the transfer zone that includes two transfer BTR rolls with alternating transfer operations, but simultaneous transfer for short periods. Two vacuum assist rolls, one located between the two bias transfer rolls controls the formation of the web loop. A pair of nip forming rolls upstream of the first transfer station and a second vacuum assist roll downstream of the second transfer station control the size of the loop.

A method and apparatus for lifting an elevator plate of a media tray in an image production device is disclosed. The method may include receiving a request to print a print job using stacked media from one of one or more media trays, initiating lifting of the leading edge of the elevator plate so that the stacked media may be received by the one or more feeder rollers, initiating printing of the requested print job from the one of one or more media trays, determining if the amount of stacked media in the one of the one or more media trays is less than a predetermined amount, wherein if it is determined that the amount of stacked media in the one of the one or more media trays is less than the predetermined amount, initiating lifting of both of the leading and trailing edge of the elevator plate so that the stacked media may be received by the one or more feeder rollers.

Systems and a method for image forming systems to skip over the non-printing photoreceptor area in order to not skip a label position on a continuous print web medium. A vacuum assembly is coupled to a controller that controls different vacuum pressures at each vacuum roller therein. The vacuum rollers provide drag and drive forces to skip a seam of the photoreceptor and a residual length based on the number and size of images on the photoreceptor.
