Patent ID: 7710441

Claim:
A method of operating an electrophotographic device comprising: sweeping a beam emitted by a laser source across an image area of a photoconductive surface, thus defining a scan line for each sweep of said beam, each sweep of said beam comprising a first part directed to a first block of adjacent print elements on the photoconductive surface and a second part directed to a second block of adjacent print elements on the photoconductive surface, the first and second parts of said sweep of said beam are not interstitial with each other; designating at least a first part and a second part of each line of image data corresponding to said first part and said second part of each associated sweep of said beam, respectively, across said photoconductive surface; and for each line of image data: modulating said laser source based upon said first part of said line of image data during said corresponding first part of a first one of said associated sweeps of said beam, wherein said laser source is not modulated according to image data for said second part of said first one of said associated sweeps of said beam; and modulating said laser source based upon said second part of said line of image data during said corresponding second part of a second one of said associated sweeps of said beam, wherein said laser source is not modulated according to said image data for said first part of said second one of said associated sweeps of said beam.
