Step 6: secondary transfer
The secondary transfer roller, to which a dc positive bias is applied, imparts a positive charge to
the print media. When the print media comes in contact with the transfer belt, the toner is
transferred to the print media.
Note When secondary transfer is complete, a dc negative bias is applied to the secondary transfer
roller to prevent toner on the transfer belt from adhering to the secondary transfer roller.

Step 7: separation
The elasticity of the print media causes it to separate from the transfer belt. A static charge
eliminator aids separation by weakening any electrostatic adhesion.
