Abstract: A mechanism for providing edge enhancement or attenuation in a vector error diffusion process includes warping a marking decision color space as a function of at least one pixel value of a target pixel. The warping changes the membership of sets of error modified pixel values associated particular sets of marking. The warping is controlled by a function of pixel values of a target pixel from an input image. Therefore, the warping is constant for uniform portions of the image. Since pixel values change at edges or where colors change, a mechanism is provided for the presence of edges to influence the vector error diffusion process. Selection of the function by which the marking decision color space is warped provides a means for controlling the aggressiveness of the edge enhancement or attenuation. Equivalent processing includes warping or adjusting error modified pixel values according to corresponding functions.

Abstract: Systems and methods are described that facilitate correcting for paper process direction arrival errors during a print job in a marker module of a print engine. Paper sheet arrival time is determined at a first registration point in a print engine or marker module thereof, and an average arrival time is compared to an expected arrival time to determine whether the pages are arriving on time, early, or late. The arrival time error is used to generate or look up a correction factor, which is added to an expected arrival time at a second registration point in the marker module or print engine to generate an updated expected arrival time. Print engine control parameters (e.g., sheet feeder timing, toner application, paper path speed, etc.) are adjusted according to the updated expected arrival time at the second registration point.
