Method and apparatus for electrophotographic laser video modulation and decode for spot fidelity

摘要

A method of driving a laser device in an electrophotographic machine includes providing a binary image data signal having a first switching rate. A plurality of binary encoded data signals are transmitted over a transmission medium. Each of the encoded data signals is dependent upon the image data signal and has a respective second switching rate lower than the first switching rate. The image data signal is recreated by using the encoded data signals. The laser device is driven with the recreated image data signal.
