Paper: Energy Analysis for Backward Wrap-Nip Fuser for High-Speed Continuous Form Laser Printers
Abstract:Backward wrap-nip fuser system has an advantage for super high-speed fusing in continuous form laser printers for heavy-duty use. The fuser is mainly composed of a heat roll, a back-up roll and a pre-heater. A nip region is formed between the two rolls. The fuser has a wrap region on its heat roll just after its nip region. Additional thermal energy is supplied in the wrap region and it enables to supply sufficient energy to toner on the continuous paper in super high-speed printing.
Local energy supply characteristics in the nip and the wrap regions are analyzed for designing the backward wrap-nip fuser system with effective energy supply. It is clarified that very high energy is supplied in very short period in the nip region and relatively gradual energy supply is made in longer period in the wrap region just after the nip region.

For more than 25 years, NIP has been the leading forum for discussion of advances and new directions in non-impact and digital printing technologies. A comprehensive, industry-wide conference, this meeting includes all aspects of the hardware, materials, software, images, and applications associated with digital printing systems, including drop-on-demand ink jet, wide format ink jet, desktop and continuous ink jet, toner-based electrophotographic printers, production digital printing systems, and thermal printing systems, as well as the engineering capability, optimization, and science involved in these fields.
Since 2005, NIP has been held in conjunction with the Digital Fabrication Conference.
