6. TONER TANK
6.1 TONER AGITATION
Under the following conditions, the toner agitator [A] inside each toner tank
rotates to agitate the toner inside the toner tank.
• Whenever the main switch is turned on while the hot roller temperature is
below 110°C.
• After a multi-copy job is completed and more than 50 copies have been
made since the last toner agitation.
•
When the optional ARDF is used, the machine stops the copy cycle after
150 copies have been made since the last toner agitation.
•
When the toner tank is pushed in during a near toner end or toner end
condition.
As shown above, one cycle of this agitation consists of rotating in both
directions, and is performed for five consecutive cycles.
In order to prevent unnecessary toner from entering the development unit
during agitation, the transport screw gear [B] has some play before rotation
is transmitted to the transport screw.
