Abstract: Embodiments described herein include a substrate media registration system in a printing system. The registration system can include a deskewing system, a reflexive system, and a controller. The deskewing system is configured to deskew substrate media. The reflexive system is configured to detect the lateral position of the substrate media and at least one of a lead edge and a trail edge of the substrate media being transported in the process direction. The controller is operatively coupled to the reflexive system and is configured to control ejection of ink from a print head system in response to detecting the lateral position of the substrate media and at least one of the lead edge and the trail edge of the substrate media.

Abstract: According to aspects illustrated herein, there are provided systems for conveying a sheet article into an intended pathway. The multi-way gate system for diverting sheets into multiple pathways in a sheet conveying device includes at least three pathways for directing the sheet from the sheet conveying member in a particular direction. A single gate plate is between the sheet conveying member and the pathways. The single gate plate is rotatable about a single axis to direct the sheet exiting the sheet conveying member toward one of the pathways.

Abstract: A method of operating a printer produces duplex images with improved throughput. The method monitors the position of an area of pressure roller that carries release agent and synchronizes a media transport to insert a media sheet into a nip formed with the pressure roller so the release agent on the pressure roller exits the nip as the leading edge of the media sheet enters the nip. The circumference of the pressure roller is an integral number times the length of the media sheet plus inter-document gap.

Abstract: A printing system comprises a paper path architecture for parallel printing using multiple marking engines. The media path configuration enables all the media feed trays to be located in one place, relative to the marking engines. A cross-over module is located between marking engines. The cross-over module can interleave media sheets that are being transported away from a first marking engine with the sheets being transported to the second marking engine. The cross-over module also includes a straight through path that enables media sheets to be transported directly to a finishing device without going through either marking engine. The marking engines include internal duplex loops such that media can be supplied to each engine in alternate groups. A merge module selectively merges the media which can then be further processed in a finishing transition module prior to communication to a finishing device.

Abstract: A method of using a buckle for relieving the stresses in sheets caused by differential displacements of drive nips during the registration process includes creating a buckle between pre-registration nips and registration nips. The velocities of the pre-registration nips and registration nips are closely controlled so that the magnitude of buckle between them is large enough to relieve the stresses in the sheet during the registration process, yet small enough to not interfere with the registration process.

In the second position, the nudger roll is not in contiguous contact with the substrate stack or the first substrate. A feed roll for further advancing the first substrate in the direction of advancement. A retard member forming a nip with the feed roll. The retard member is used for separating the first substrate from an adjacent second substrate.
