3.2 CHARGE CORONA WIRE CLEANER MECHANISM

[A]
The flow of air around the charge corona wire may deposit paper dust or
toner particles on the corona wires. These particles may interfere with
charging and cause low density bands on copies.
The wire cleaner pads [A] above and below the charge corona wires clean
the wires as the charge corona unit is manually slid in and out.
The cleaner pad bracket [B] rotates when the charge unit is fully extended
and the bracket is pulled up against the rear block [C]. This moves the pads
against the corona wire (see illustration). If the charge unit is not fully
extended, the pads do not touch the corona wires.
The pads move away from the wire when the charge unit is fully inserted and
the cleaning bracket is pushed against the front block [D].
After copier installation, the key operator should be told how to use this
mechanism when white streaks appear on copies.
