2 UNIT EXPLANATION
TONER SUPPLY UNIT
[1] Composition
[2] Mechanisms
*1 Toner agitation
Toner agitator plates are driven by the following
two motors through the gear unit:
a) Toner supply motor 1 (M11): Drives the toner
supply screw.
b) Toner supply motor 2 (M15): Drives the toner
cartridge.
The agitator plates rotate faster when toner supply
motor 1 (M11) runs than when toner supply motor 2
(M15) runs. When the two motors are running simulta-
neously, the one-way clutch installed on the agitator
shaft selects toner supply motor 2 (M15).
The agitator plates prevent the toner from clumping
and accumulating on TLD (remaining toner detection
sensor).
