IMAGE TRANSFER AND PAPER SEPARATION

2.5 IMAGE TRANSFER AND PAPER SEPARATION
2.5.1 OVERVIEW
The machine uses a transfer roller [A], which touches the surface of the drum [B].
The Power Pack - B/C/T supplies a positive current to the transfer roller, which
attracts the toner from the drum onto the paper. The current depends on the paper
width, paper type, and paper feed tray.
Drive from the drum through a gear turns the transfer roller. The antistatic brush [C]
helps the paper to separate from the drum. The antistatic brush is grounded.
Use SP2-301 to adjust the transfer current. Note that when adjusting SP2-301-2
(by-pass tray), the transfer currents for both normal and thick paper are changed
(but not the setting for "Special" paper - adjust that with SP2-301-5).
