    摘要： Correction data is produced for density errors in prints produced using a printer (100). While printing a test image, the periods of rotation of one or more rotatable imaging members (25, 55) arranged along a receiver feed path in the printer are measured using respective period sensors (51). The printed test image is measured in both the cross-track and in-track directions and a two dimensional map of the density for the one or more period sensors is determined. A reproduction error signal representing deviation from aim density is determined. The variations from the data at measured periods in one or both directions are used to produce a correction signal.

    摘要： A dynamic positional shifting, in the process direction, of the images on the second print engine of a tandem machine printing system in order to increase the time (and number of prints) between skipped pitches. Although the photoreceptor belts of each print engine may be out-of-phase, the relative positions of their individual seam zones may be derived during cycle-up. A control procedure then optimizes the position and spacing of each image within each belt revolution of the second engine, while still maintaining the minimum inter-document zone (IDZ) length required for paper path feeding and registration, xerographic process controls, and finishing. Removing the constraints of fixed-dimension IDZ's, as well as being able to adjust spacing and length of individual images on the belt, allows for optimization of system productivity by either delaying or eliminating the need for a skipped pitch.
