Pad Transfer System for Small Color Laser Printer
Abstract:Canon has newly developed a transfer system that utilizes a pad as a transfer process, and adopted it on a small color laser printer, LBP5050. During transfer process, it is necessary to provide an enough transfer electric field to toner as regulating scattering caused by pre-transfer and discharge marks by separating discharge. This report clarifies that, with the conventional roller transfer system, it is necessary to minimize an upstream tension nip width, and maximize a physical nip width and downstream tension nip width in order to achieve an optimal condition. Also, by comparing the pad transfer system and the roller transfer system in their abilities to transfer, this report estimates problems that could occur in minimizing the size of devices with the roller transfer system and concludes, with the use of pad transfer system, those problems can easily be resolved. Ultimately, the pad transfer system is superior in its compactness and image quality to the roller transfer system.

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.
