Step 5 Secondary transfer
The toner on the intermediate transfer belt is transferred to the paper in this step. The paper
is pressed against the intermediate transfer belt when the secondary transfer roller contact cam
lifts the secondary transfer roller.
The DC bias (positive) is applied to the secondary transfer roller and the toner on the inter-
mediate transfer belt is transferred to the paper.
To prevent smudging of the back of the print paper, the DC bias (negative) is applied after
during INTR and LSTR periods to move the toner on the secondary transfer roller to the inter-
mediate transfer belt and clean the secondary transfer roller.
