bottle cap and the toner shutter [D] closes and blocks the opening.
Toner Supply Mechanism
The toner supply motor [A] rotates the toner bottle [B] and the mylar blades [C].
Toner falls into the toner bottle holder, and the toner supply mylar blades [C] transfer the
toner to slit [D]. Installing the PCU opens the shutter [E]. The toner falls into the development
unit through the slit.
Toner Density Control
There are two modes for controlling and maintaining constant toner supply: sensor control
(both direct and indirect) and image pixel count control. The mode can be changed with
SP2208-01 (Toner Supply Mode).
The factory setting is sensor control mode. Image pixel count mode should only be
used temporarily until a defective TD or ID sensor can be replaced.
