2.2.9 TRANSFER AND SEPARATION
Instead of using a transfer corona wire, this machine uses a transfer roller, which
touches the drum surface.
The power pack [A] applies a constant current of +4.3
µ
A to the transfer roller [B].
The positively biased transfer roller pulls negatively charged toner off the drum.
The curvature of the drum and the anti-static brush help the paper to drop away
from the drum.
