8.3 PAPER SEPARATION
[A]
A171D602.img
To break the attraction between the paper and the drum, the separation
corona applies an ac corona to the back side of the paper. The stiffness of
the paper then causes it to separate from the drum. The pick-off pawls [A]
which are installed on the cleaning unit assist paper separation.
Two corona wires are used to improve separation by widening the discharge
area. Also, a larger corona current is applied at the leading edge of the paper
for the same purpose.
