Cleaning/toner recycle unit
Composition
Mechanisms
*1 Toner collection
Toner removed by the cleaning blade is
collected by the toner guide roller (TGR)
and removed by the scraper, then
conveyed by the toner conveyance
screw to be reused. High pressure is
applied to the toner guide roller (TGR)
to enhance the toner cleaning ability.
*2 Toner recycle
When the drum performs preliminary
rotation as warm-up, toner recycle MC
(MC14) is turned off, stopping the drive
force from the toner conveyance screw.
This prevents excessive recycled toner
from being conveyed to the developing
unit.
