DRUM CLEANING AND TONER RECYCLING

6.10 DRUM CLEANING AND TONER RECYCLING
6.10.1 DRUM CLEANING
The cleaning blade [A] removes any toner
remaining on the drum after the image is
transferred to the paper. This model uses a
counter blade system.
The cleaning blade scrapes off toner
remaining on the drum. When toner builds up
in the cleaning unit, toner at the top of the pile
is removed by the toner collection coil [B].
To remove the toner and other particles that
are accumulated at the edge of the cleaning
blade, the drum turns in reverse for about 5
mm at the end of every copy job.
6.10.2 TONER RECYCLING
Toner picked up by the toner collection coil
[A], is transported to the opening [B] in the
side of the PCU. Then, this toner falls into
the development unit with new toner coming
from the toner bottle and it is all mixed
together by mixing auger 1 [C] and used
again.
