Allignment of color planes in multi-beam multi-pass printers
Abstract:
Methods and apparatuses that facilitate the alignment of multiple color planes of a latent image in a multi-beam multi-pass printer are described herein. The novel methods includes determining, during a first pass of a transfer medium of a multi-beam printer, a first time interval between when at least one light beam from a multi-beam device is detected and when a top of a page is detected at a selected location of the transfer medium, the multi-beam device including a plurality of light beam sources, and the first pass to form a first color plane of a latent image on the transfer medium. The methods further include selecting, based at least in part on the determined first time interval, a first one of the plurality of light beam sources to begin illuminating the transfer medium to create the first color plane on the transfer medium during the first pass of the transfer medium.
