Abstract:
1. A bi-directionally scanning electrophotographic device, comprising; a photoconductor for being impinged with a plurality of scan lines formed in alternating directions to create a latent image; a nonvolatile memory, the memory including modeled parameters, the modeled parameters including one of temperature and pressure relative to scan misalignment; and a controller for producing the latent image on the photoconductor to create a printed image from the latent image, wherein the controller has local or remote access to compare modeled and learned parameters characterizing the scan lines to printed scan lines of the printed image; wherein the modeled parameters include misalignment profiles, each profile corresponding to a different misalignment value for one of pressure and temperature, one or more of the misalignment profiles are substantially V-shaped having an apex substantially along a centerline of the scan lines, and the one or more of the misalignment profiles provides a misalignment amount y which approximately follows the equation y(x)=[((2
