6.4 PAPER SEPARATION AND TRANSPORTATION

[A]
The discharge brush [A] and the curvature of the drum help the paper to drop
away from the drum. The high voltage supply board [B] applies a constant dc
⇒
voltage, -2 kV (when feeding from a paper tray), or -2.5 kV (from the duplex
tray) to the discharge brush.
The transport vacuum fan helps to transport the paper from the transfer area
to the fusing unit. The transport vacuum fan turns on and off at the same time
as the main motor.
The discharge brush voltage can be adjusted using SP 2-901 (there are
separate settings for the front and rear side, and for the leading edge and
other areas of the paper).
