In February, 2006, RICOH Company, Ltd. launched the Ricoh imagio MP9000/1100/1350 series (Aficio MP9000/1100/1350) designed for a high speed digital monochromatic Multi Functional Printer. The Organic Photo Conductor (OPC) applied to this machine had a life of two millions prints (Letter). The durability of the OPC had been dramatically increased than ever before. In attempting to increase durability of OPC, we tried to prevent the occurrence of background fouling, which deteriorates with long term of use and largely influences on the life of OPC. As a result of our study, we developed the following three methods to achieve our object: (I) Adopting blocking layer to improve hole-blocking ability. (II) Increasing the thickness of charge transport layer (CTL). (III) Optimizing cleaning condition to minimize CTL abrasion rate.

  • 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.
