Step 6: Transfer
The toner on the photosensitive drum is transferred to paper.
The transfer roller is located at the opposite side of the photosensitive drum across the ETB. A positive DC bias is applied to the transfer roller.
Since the ETB is charged positive by the transfer roller, the negative-charged toner on the photosensitive drum is transferred to the paper.
This process is executed in the order of M, C, Y, and Bk.
F-7-8
Step 7: Drum separation
The paper is separated from the photosensitive drum by its own elastic force (curvature separation).
There is also a static charge eliminator at the downstream of the transfer roller. It decreases the static charge on the ETB to stabilize paper feed operation.
F-7-9
Step 8: ETB separation
The paper is separated from the ETB by the elasticity of paper and the curvature of the ETB feed roller.
