Transfer
Drum
1. A latent image is written to each OPC drum by the laser unit. There are 4 separate laser
beams, one for each color drum.
2. Each drum is charged with a negative charge using a charge roller.
3. When the laser beam hits the drum, it neutralizes the charge in the area where the beam
strikes the drum, creating a latent image.
4. Negatively charged toner (one color for each drum) is attracted to the discharged areas of
the drum (latent image) and develops a toner image on each drum.
5. The developed toner image (on each drum) is then transferred to the Image Transfer Belt
(ITB) to create a full color image on the surface of the ITB.
6. The full color image is again transferred from the surface of the ITB to a passing sheet of
paper. The image on the sheet of paper is then sent to the fusing unit to fuse the image
permanently to the paper.
