5) After entering the data, close the front cabinet.
6) 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.

Note: Be sure to select all of the four colors: K, C, M, Y.
7) Exit from Simulation mode by pressing the [CA] key on the
main unit.
G. Installation of individual color toner cartridges
* The life of each toner cartridge is as follows:
