    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 method and system feeds a sheet through a media path in a process direction. When the sheet is within a sheet registration carriage of the media path, the method and system align the sheet to a predetermined lateral position within the media path. The aligning process comprises unevenly activating nips within the sheet registration carriage and moving the sheet registration carriage in a lateral direction perpendicular to the process direction. When the sheet is within the sheet registration carriage, the method and system determine a lateral movement distance the sheet registration carriage will move in the lateral direction during the aligning of the sheet. If the lateral movement distance exceeds a predetermined distance, the method and system move the sheet registration carriage toward the starting position after the nips have released the sheet, but before the sheet has passed by the nips. If the lateral movement distance does not exceed the predetermined distance, the method and system delay moving the sheet registration carriage toward the starting position until after the sheet has passed by the nips.

    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 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.
