Super-high speed continuous feed B/W laser printers are used for mission critical printing tasks in corporate and government offices. Very high volume printing jobs are printed in any printing occasions including peak tasks. Therefore, productivity in printing is the most important and very high-speed, durability and reliability are required for the printers.
In this report, overview for the printers is described. Then, optical, developing and fuser systems, which give significant affection to imaging process technological concepts for the system productivity, durability and reliability, are explained in detail. In optical system, technologies for multi-beam scanning in wide and high-speed printing are explained. In developing system, imaging technologies for obtaining high image quality and durability are described and harmonized developer mixing method with the imaging is explained. Finally, fuser system in super high-speed printing for supplying sufficient fusing energy in very short period and technology for correcting continuous paper meandering are introduced.
