Initializing the developer unit (toner install mode)

Description
The new developer unit is shipped from the factory with no toner contained. The developer can
be automatically replete with toner when a toner container is installed onto it and the printer is
turned on. However, because the toner reservoir in the developer has a large capacity, it
requires a lengthy period of time until a substantial amount of toner has been fed to get the
printer ready. (A new developer needs approximately 100 g for triggering the sensor inside.)
