Developer Initialization (Toner Install Mode) - Kyocera FS-1900 Service Manual

(5) Developer initialization (Toner install mode)

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.)
A great many seconds of time for this is greatly deducted by using the service menu in the printer's
mode select routine as accessed by its operation panel. Follow these steps to use this feature, top to
bottom (For details, refer to section 2-3 Using the operator panel on page 2-18).

Note: If the printer is switched off in the middle of developer
initialization, even after the printer is switch on again, the printer
will automatically resumes developer initialization. To cancel the toner
install mode in this case, first turn power off, press and hold all three
paper size switches (See the figure above.), and turn power on. Let
go off of the switches when the until message changes to Ready.
