Abstract
Official abstract text for this publication.
An apparatus for reducing registration errors in a media handling device. The apparatus including an image-bearing member having sheets individually pass across the image-bearing member. Each sheet pass corresponds to one of a series of iterations between the image-bearing member and the sheets. The image-bearing member is operatively coupled to a controller for regulation motion of the image-bearing member. The controller receives input signals representing at least one measured disturbance. Each disturbance being defined by a pattern of image-bearing member movement away from and substantially returning to a reference state of motion. A repetition of the pattern being coincident with at least one of the iterations, wherein based on the measured disturbance, the reference state and an indication associated with when the pattern will repeat, a modified signal is generated for the actuator to adjust the image-bearing member motion in coordination with the indication.
First claim
Opening claim text (preview).
What is claimed is: 1. An apparatus for reducing registration errors in a media handling system, the apparatus comprising: a first image-bearing member and a second image-bearing member, the first and second image-bearing members conveying marking material corresponding to at least a portion of an image, wherein each of the image-bearing members interact with sheets of substrate media as the sheets individually pass across the respective image-bearing members, wherein one sheet pa…
