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.

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.
