Step 4: Transfer The positive DC bias is applied to the transfer roller. As the media passes between the transfer roller and the photosensitive drum, the transfer roller applies a positive DC bias to the media. The positively charged media attracts the negatively charged toner from the drum surface. Figure 3-11 Transfer Photosensitive drum Transfer roller Media DC bias Step 5: Separation The elasticity of the print media causes its separation from the photosensitive drum. A static charge eliminator aids separation by weakening any electrostatic adhesion.

Step 4: Transfer
The positive DC bias is applied to the transfer roller. As the media passes between the transfer roller
and the photosensitive drum, the transfer roller applies a positive DC bias to the media. The positively
charged media attracts the negatively charged toner from the drum surface.
