6.5.3 DEVELOPER AGITATION
Two mixing augers [A and B] circulate the developer forward and backward to
agitate the developer.
This happens at the following times:
• During process control self check
• During toner supply
• During development.
Ducts on the top of the developer hopper [C] make sure that the internal pressure
does not become too high. These ducts are sealed to not let the toner solidify.
This development unit does not operate very well at high temperatures (over 50°
C). The toner inside the development unit can become solid at temperatures higher
that this value. A developer initialization error shows if the toner does become solid.
At this time, you must do the following procedure:
NOTE: You should also do this procedure when you install a new development
unit.
1. Remove the (old) development unit.
2. Keep the (new) development unit level and shake it several times from side to
side.
3. Install it to the machine.
