摘要： Methods and devices detect a first lateral measure of an edge of a belt loop supported by rollers within an apparatus using a first sensor to find an amount of misalignment of the edge of the belt loop relative to a known alignment position. The first sensor is positioned at a first location within the apparatus. The methods and devices also detect a second lateral measure of the edge of the belt loop within the apparatus relative to the known alignment position using a second sensor. The second sensor is positioned at a second location within the apparatus that is different than the first location. The methods and devices use a processor to determine the non-linear shape of the edge of the belt loop based on the second lateral measure of the edge of the belt loop detected by the second sensor. The methods and devices correct the amount of misalignment detected by the first sensor based on the non-linear shape of the edge of the belt loop to generate a corrected misalignment value, using the processor. Further, the method and devices adjust the current lateral position of the belt loop within the apparatus relative to the known alignment position based on the corrected misalignment value using a belt tracking actuator that is operatively connected to the processor.

摘要： Systems and methods for positioning a sheet in a feed path including at least one sheet drive roller driven in a rotational direction by a drive shaft in which the drive shaft translates in a lengthwise direction along the axis of the drive shaft. A power shaft rotates about the same axis as the drive shaft and is driven by a power source that is fixedly mounted in the system. The power shaft is fixed to the drive shaft by a flexible coupling that allows the drive shaft and the power shaft to move relative to one another in the lengthwise direction along the axis while maintaining corresponding rotational motion between the power shaft and the drive shaft.

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.).
