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： A sheet registration system, especially for printers, with a lower cost and lower mass-movement system for both sheet deskewing and transverse registration repositioning of the sheets in the same integral system, especially for higher speed printing. Only one main drive motor can drive both of the two spaced apart sheet feeding nips, together with a lower power, lower mass, deskewing differential drive system for providing the relative differential angular movement of the two spaced sheet feeding nips to achieve the desired amount of sheet deskewing movement, without interrupting the forward feeding movement of the sheet. Also disclosed are extensive further reductions in the component mass of the lateral translation movement for lateral sheet registration.
