Abstract

In a brush cleaner approximately one-~half of the power is used to clean the cleaning brush0 This results mainly from the inefficient use of the air flow in toner detachment and capture0 For example, the net airflow of a cleaning system is about 120 cubic feet per minute of which about 20 cubic feet per minute is needed for the conveying and separation of the toner, It appears that the air flow could be cut from 120 to 40 cubic feet per minute by more efficient use of the air, This can be achieved by applying the major portion of the air flow at the flicking region.

In a brush cleaner approximately one-~half of the power is
used to clean the cleaning brush

                          0 This results mainly from
the inefficient use of the air flow in toner detachment and
capture
0 For example, the net airflow of a cleaning system
is about 120 cubic feet per minute of which about 20 cubic
feet per minute is needed for the conveying and separation
of the toner, It appears that the air flow could be cut
from 120 to 40 cubic feet per minute by more efficient use
of the air, This can be achieved by applying the major
portion of the air flow at the flicking region.

Three paths for air flow past the flicking region are pro~
vided: Through the brush, through the flicking bar and
around the flicking bar, The air flow is divided roughly
1 to 2 to 1, respectively

             0 For example, a total flow
through the system of 40 cubic feet/minute produces velocity
in the flicking region of approximately 6000 feet/minute.

The pressure drop across the brush housing would be about
2,3 inches of water, A substantial savings in power for
cleaning results.
