A DC bias (negative component) is applied to
the roller electrode to collect any excess toner
that did not move to the surface of the drum by the
roller electrode, limiting soiling of the pre-transfer
charging assembly and the transfer charging
assembly.

B. Separation Claw
Figure 2-202
If copy paper fails to separate from the photo-
sensitive drum because of a pre-transfer charging
fault, separation charging fault, or feeding fault, it
could move into the cleaning assembly.
To prevent such a problem, a separation claw
is located at the bottom of the cleaning assembly;
the claw forces off copy paper from the drum,
thereby keeping it from moving into the cleaning
assembly.
