Toner High level State
• The agitation bar interlocks and turns with the
agitation gear.
• Since there is a toner even if a agitation bar
reaches the maximum height, the other side
of the bar is still inside the toner. Therefore,
the agitation bar turns by the force of the
agitation gear.
Toner Low Level State
• When the agitation bar reaches the maxi-
mum height, the agitation bar falls in the
minimum height by prudence since there is
no resistance by the toner. At this time, the
minimum height length of stay of a target
board becomes long. This time is measured
and a toner low level state is detected.
Toner Supply Operation
• When continuation 3 cycle detection of the
toner low level state is carried out, a toner
supply roller and a toner cartridge agitation
spring will rotate, and the toner of a toner
cartridge will be supplied to the inside of an
image drum cartridge. Then, when one cycle
of toner high level is detected, toner supply
agitator and a toner cartridge agitation spring
will stop, and toner supply will stop.
