Abstract
A method for reducing electromagnetic emissions by an image scanner comprises cyclically dithering a frequency of a clock signal of the image scanner by repeated dither cycles, determining a phase of the dither cycle when a scan pass of a page of a document commences; and commencing all subsequent scan passes of the page of the document at a particular phase shift from the determined phase of the dither cycle.
