2. Product Specifications and Description2.7.2. Laser Scanning Optical pathThe laser beam from the LSU is placed at intervals of 78mm for each color. All colors uses the same polygon motor foroblique incidence.F2 Lens [A] determines the slope of the primary scanning line and the image position of the secondary scanningdirection. This is adjusted at the factory. The primary scanning line slope by the machine difference is adjusted by skewadjustment in the LSUReflecting mirrors [C], [D] on each color path adjust the curvature of primary scanning. This is adjusted at the factory.The LSU has 2 types depending on printing speed. The difference between 2 types is shown in the table below.Mode 20ppm 30ppm RemarkLD Unit Laser Diode : Single Beamdriving IC : for Single LDLaser Diode : Single Beamdriving IC : for Single LDP/Motor speed 27,874 rpm 34016 rpmProcess speed 118 mm/sec 144 mm/secH/W interface Interface with machine : 50PinInterface with machine : 50PinFFC cableCopyright© 1995-2013 SAMSUNG.
