International Classification:

B41J 1142

US Classification:

400579, 400578, 399394, 347129, 271 2, 250208

Abstract:

The present invention generally relates to a printing apparatus including a marking device, the marking device being capable of placing an image on a sheet fed therein, and outputting the sheet; a feed path, by which sheets are fed from a sheet supply to the marking device; a duplex path, by which sheets output from the marking device are re-fed to the marking device; a first sensor, outputting a first position signal relating to a location of a side edge as each sheet passes through the feed path; a second sensor, outputting a second position signal relating to a location of a side edge as each sheet passes through the duplex path; and an image placement controller associated with the marking device, the image placement controller retaining first position signals for a plurality of sheets passing through the feed path and second position signals for a plurality of sheets passing through the duplex path, and calculating new average paper positions for each sheet in response to at least one of the first position signals and the second position signals.

International Classification:

B65H 306

US Classification:

271119, 271120, 271109, 271113, 492 30, 492 25

Abstract:

A self-adaptive sheet feeding roll for reliably feeding, within a sheet feeding apparatus, sheets of various and different sheet weights along a sheet path. The self-adaptive sheet feeding roll includes (a) a cylindrical core having a longitudinal axis and an outer surface; (b) a compliant surface layer formed over the outer surface of the cylindrical core and having an external surface and a given layer thickness; and (c) a series of spaced apart, non-radial slots formed from the external surface into the compliant surface layer and defining a series of spaced apart blade portions within the compliant surface layer for adaptively compressing and deforming against, and responsively to, sheets of various and different sheet weights, thereby self-adjusting a normal force Fn as well as a sheet driving force Fd thereof and enabling reliable feeding, within a sheet feeding apparatus, of such sheets of various and different sheet weights.

Abstract:

Parallel printing systems and methods incorporate inverter assemblies for not only inverting media during transport through the system but also to register the media or provide a velocity buffer transports with different drive velocities. The inverter assemblies can include the capability to optionally deskew the media and provide lateral registration corrections. The inverter assembly nip rollers are sufficiently spaced from process drive nip rollers to decouple a document in the inverter assembly from the highway paths. The method comprises combining the inverting function selectively with either the registering or the velocity buffering functions.

US Classification:

700126, 700 97, 700 98, 700122

Abstract:

A printing apparatus, method, and computer program of designing a floating roller in a tensioning system adapted to one of supply and receive a web of material to or from one of a web supply and a processing machine, comprising inputting external radius of said floating roller, measure of elasticity of the material, a thickness of the material, width of the material, and angles at which the material contacts the floating roller; and adjusting mass of the floating roller and rotational inertia of the floating roller based on external radius of the floating roller, measure of elasticity of the material, thickness of the material, width of the material, and angles at which the material contacts the floating roller such that the floating roller maintains a constant tension on the web of material as the material is passing through the tensioning system.
