  • Page 22 2. Operational explanation Oki Data CONFIDENTIAL 6. Drum cleaning After completion of transfer, the toner remaining on the image drum is scraped off by the cleaning blade. As a result of this, the surface of the image drum is cleaned, and the remaining toner that has been scraped off is collected as waste toner in a waste toner area.

  • Page 23: Printing Process

    2. Operational explanation Oki Data CONFIDENTIAL 2.2 Printing process The paper fed from Tray 1 and Tray 2 is conveyed by feeding roller, conveying roller, and resist roller. When feeding paper is from MPT, it is conveyed by MPT, feeding roller, and resist roller. After that the feeding paper that is conveyed by image drum and the nip part of transfer roller forms toner image on the paper through electrophotographic process.
