摘要： A closed loop feedback method that continuously adjusts the lateral and skew position of a sheet includes a first sensor that is used to measure lateral sheet edge position. A second sensor measures the lateral sheet edge position at a certain distance from the first sensor. Sheet skew values can thus be calculated. Lateral and skew controllers provide outputs to lateral and skew actuators, respectively, to adjust the sheet position. A different method of registering sheets laterally and in skew enables active sheet deskew without translating the sheet in the cross-process direction. A sensor carriage position is controlled to find the sheet edge after which deskew control can start. The average value of the carriage position can then be fed in a feedforward manner to move the image location to match the average paper position. This achieves good average lateral registration and active skew control at a reduced cost.

摘要： An encoder idler roll includes an integral idler roll/encoder structure that forms an enclosed housing with a portion of the surface of the idler roll becoming the inner race for the encoder, as well as, the media encoding surface. Additionally, this integral idler/encoder configuration minimizes run out, improves tolerances between parts and stabilizes clearances between the idler roll and its support shaft.

摘要： In a system of automatic deskewing and registration of print media sheets moving in a printer paper path with laterally spaced apart differentially driven rollers controlled by the sensing of the moving sheet lead edge skew at a position downstream in said paper path there is further provided a subsequent trail edge sheet skew detection of the same moving sheet at a position upstream of the differentially driven rollers to subsequently differently control the differential driving of those same rollers to make a final and normally much smaller deskewing correction in the same sheet after the majority but less than all of said sheet is downstream of the differentially driven drive rollers.

摘要： A method for improving color-to-color registration in a printing device. The method includes printing a plurality of multi-color images, measuring the relative locations of a first portion of each multi-color image having a first color of each image and a second portion of each multi-color image having a second color of each image, for each image, comparing at least one difference between the first portion's location and the second portion's location with at least one desired difference between the first portion's location and the second portion's location to generate a list of positional errors, using a least square regression analysis of the list of positional errors to determine shift amounts required for placement of each first portion in subsequently generated images to within a desired degree of accuracy, and adjusting the placement of the first portion of each subsequently generated image by the determined shift amounts.

摘要： A free sheet, high speed, color tandem printing system that controls registration of images from one imager to another while mechanically decoupling individual imagers and all the while maintaining relative registration of each of the color separations by the use of spherical transport servo devices or spherical nips (SNIPS). SNIPS correct skew, lateral, and process positions and ensure proper registration of a sheet with a station.
