Toner Supply Mechanism
The toner supply motor [A] drives the toner bottle [B] and the mylar blades [C]. First, the
toner falls down into the toner bottle holder. The toner supply mylar blades transfer the
toner to the slit [D]. When the PCU is installed in the machine, the shutter [E] above the
PCU is opened by the machine frame. Then the toner falls down into the development unit
through the slit and the shutter.
6.9.6 TONER DENSITY CONTROL
Overview
There are four modes for controlling toner supply as shown in the following tables. The
mode can be changed with by SP2-921. The factory setting is sensor control 1 mode.
Basically, toner density is controlled using the standard TD sensor voltage (Vts), toner
supply reference voltage (Vref), actual TD sensor output voltage (Vt), and ID sensor output
data (Vsp/Vsg).
