摘要： According to aspects illustrated herein, there is provided a method, a system, and a printmaking device for calibrating sensors. The method begins by transporting a media sheet along a media path, the sheet having a lead edge, a trail edge and a measurement edge. Next, the method halts the forward motion of the sheet after the lead edge of the sheet passes a fixed reference. After that, the method moves the sheet laterally relative to the media path across the at least one edge sensor using a sheet actuator. Then, the method records an actual position of the sheet actuator and an output of at least one edge sensor. Finally, the method calculates a calibration factor based on the actual position of the sheet actuator and the output of the at least one edge sensor.

摘要： A method and system feeds sheets through a media path in a process direction and moves a laterally movable sheet registration carriage (positioned within the media path) in a lateral direction perpendicular to the process direction. It determines the lateral error of the sheets within the media path before the sheets enter the sheet registration carriage, using first sensors positioned within the media path. This allows the sheet registration carriage to be moved to a variable lateral starting position (as opposed to a consistent reset position or centered reset position) before the sheets enter the sheet registration carriage based on the error of the sheets as determined by the first sensors. The error can be the amount of lateral error, or simply can be a classification of lateral error (right error, left error, etc.).

摘要： A system and method are provided to calibrate a sheet velocity measurement derived from a drive nip system incorporating idler encoders. Testing has found that the velocity from an idler encoder system is subject to systematic errors, for example, errors that occur when the system is running media of different thicknesses. The system uses one or more nips with encoders mounted on the idlers and a number of point sensors that are spaced apart in the process direction. The point sensors are used to measure the transmit time of the sheet (lead edge or trail edge) between two sensor positions. The transit time is used to calculate the average sheet velocity. The average sheet velocity is compared with the velocity derived from the idler encoders to derive a correction factor. The velocity sensor are used to calibrate the idler-encoder velocity sensors, providing a worthwhile improvement to idler-encoder technology for media handling (e.g., feeding, transport, and finishing) in direct marking systems.

摘要： The presently described embodiments are directed to a method and system for improving sheet registration in a document processing device. The presently described embodiments implement a technique the produces accurate results with merely a small tail wag. To do so, the method ultimately establishes or determines a variety of parameters (e.g. lateral position of a sheet, skew, registration time, nominal sheet velocity, and correction velocity). These parameters are then used by the system to calculate a lateral velocity profile. In this regard, the calculated velocity profiles are applied to the wheels or nips, in the paper path. Thus, the wheels can be controlled and will allow for improved sheet registration in the document processing device.
