Abstract
An imaging system having a raster output scanner that produces high quality scan lines comprised of evenly spaced pixels. The raster output laser device is modulated in accordance with a variable frequency pixel clock that is derived from a high frequency oscillator using a dual modulus programmable divider that is controlled by a state machine. In turn, that state machine is controlled by information stored in a memory. The variable frequency pixel clock compensates for scan line nonlinearity, polygon facet errors, and/or scan line magnification.
