(a) Perform the key operations of simulation 25 sub 2.
With the above key operations, simulation 25 is performed and
the developer is stirred for 3 minutes.
(b) After stirring the developer for 3 minutes, the toner density
level is read by the main PWB.
During stirring, the toner density sensor level is displayed on
the MULTI COPY display. (Range: 1 ∼ 99)
