Abstract:
1. A method of operating a multi-beam printer, wherein the multi-beam printer includes a multi-beam device that comprises a plurality of light beam sources, wherein the multi-beam printer includes a transfer medium that interacts with the multi-beam device to print an image onto a print medium, and wherein the print medium comprises a page, the method comprising: detecting at least one light beam generated by one of the plurality of light beam sources of the multi-beam device; subsequent to detecting the at least one light beam generated by one of the plurality of light beam sources of the multi-beam device, detecting a top of the page of the print medium when the top of the page is located at a selected location on the transfer medium; during a first pass of the transfer medium of the multi-beam printer, determining a first time interval between (i) when the at least one light beam from one of the plurality of light beam sources of the multi-beam device is detected during the first pass of the transfer medium of the multi-beam printer and (ii) when the top of the page of the print medium is detected at the selected location on the transfer medium during the first pass of the transfer medium of the multi-beam printer, wherein the first pass forms a first color plane of a latent image on the transfer medium, and wherein the latent image is associated with the image; determining a beam detection period, wherein the beam detection period is an amount of time between two successive detections of light beams from the same light beam source during two successive cross scans of the transfer medium; and based at least in part on comparing the first time interval with the beam detection period, selecting a first light beam source 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, wherein the plurality of light beam sources include N light beam sources, where N is an integer, and wherein selecting the first light beam source further comprises
