B.Set the control level for the reference toner density
Setting of the reference toner density control level must be per- formed with the toner cartridge removed.
If setting is performed with the toner cartridge installed, the

4) After entering the simulation, close the front cabinet.
5) Select K, C, M, Y and then press the [EXECUTE] button. The system then performs the simulation, samples the toner den- sity control sensor value, and sets (stores in memory) the average sensor detection level as the control level for the ref- erence toner density. (Operating times: approx. 1.5 minutes)

Be sure to select all of the four colors: K, C, M, Y.
6) After the machine completes cycling, exit the simulation mode.
7) Confirm that “Install the toner cartridge” is displayed, and install the toner cartridge by the following procedures.
8) Shake the toner cartridge horizontally several times.
