Transfer stage
Step 4: The transfer charging roller, to which a DC positive bias is applied, imparts a positive charge on the print media. When the print media comes in contact with the photosensitive drum, the toner is transferred to the print media.

Step 5: 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 6: The DC negative bias applied to the fusing film strengthens the holding force of the toner on the print media and prevents the toner from scattering.
