Outline
10. Image Transfer
• A DC positive charge is applied to the Image Transfer Roller to transfer the visible image
on the surface of the PC Drum onto the paper.
11. Paper Separation
• The PC Drum Paper Separator Fingers remove paper from the surface of the PC Drum.
• The Charge Neutralizing Plate neutralizes any charge left on the paper.
12. Cleaning
• Residual toner on the surface of the PC Drum is scraped off.
• The toner is then recycled back to the Developing Unit.
13. Main Erase
• The surface of the PC Drum is irradiated with light and any surface potential remaining
there after cleaning is neutralized.
14. Paper Transport
• The paper is transported to the Fusing Unit.
15. Fusing
• The developed image is permanently fused to the paper by the combination of heat and
pressure applied by the Fusing Roller.
16. Paper Exit
• The paper is fed out onto the Exit Tray.
• The optional Job Separator (JS-503), when mounted on the copier, allows a specific tray,
in which paper is fed, to be selected according to the operating mode.
