CLEANING/TONER RECYCLE UNIT
[1] Composition
[2] 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 convey-
ance 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 con-
veyance screw. This prevents excessive recy-
cled toner from being conveyed to the developing
unit.
