Abstract

Brush cleaning studies have shown that when areas of the flicker bar become impacted with toner corresponding areas of the photoreceptor also become filmed or impacted with toner. It is believed that impaction is caused in part by an increase in temperature at the point of impact between the brush and the flicker bar.

MODIFIED FLICKER BAR FOR Proposed Classification
PREVENTION OF FILMING IN U.S. CL 355/15
A BRUSH CLEANER mt. CL G03g 21/00
Donald 3. Fisher

Brush cleaning studies have shown that when areas of the
flicker bar become impacted with toner corresponding areas
of the photoreceptor also become filmed or impacted with
toner. It is believed that impaction is caused in part by

an increase in temperature at the point of impact between
the brush and the flicker bar.

It is proposed that means be provided for significantly
reducing the temperature of the flicker bar in order to
help prevent wetting of the bar by the toner under the
energy of impact. One means for accomplishing this would
include the use of a hollow flicker bar through which a
refrigerant would be circulated, Other approaches could
utilize a reverse heat pipe or a Peltier type device con~
nected to a high conductivity metal flicker bar, The
Peltier effect could also be utilized by forming the
flicker bar from a Neelium bar across which a bias is
applied to produce a cold and hot junction. The hot side
would be arranged away from contact with the brush fibers,

Other methods for cooling the flicker bar as are known in

the art could also be employed.
