High resolution laser printer

摘要: A high resolution laser printer utilizes a first cylindrical lens to focus beam in the sagittal direction prior facets of rotating polygon. The light reflected from polygon is focused horizontal at photoconductor drum an electrophotographic process by scan assembly. Following assembly, there second which also focuses photoconductor. and lenses are positioned eliminate errors Scan velocity deviations resulting optical design corrected storing correction information memory using this vary rate modulated with data.
