The copier is provided with a toner recycling mechanism. The toner, which has been
scraped off the surface of the PC Drum by the Cleaning Blade and collected in the Cleaning
Unit, is conveyed by the two Toner Recycling Coils to the Toner Supply Port and, from
there, it is returned back to the Developer Mixing Chamber of the Developing Unit.
One of the gears of the Toner Recycling mechanism receives drive through a gear at the
rear end of the PC Drum.

The Imaging Unit is provided with a fuse called the I/U Fuse. When a new Imaging Unit is
installed in the copier and the Power Switch turned ON, an I/U Set signal is output causing
the copier to start the starter setup sequence and ATDC Sensor automatic adjustment.
When the starter setup sequence is completed normally, an I/U Fuse Blow signal is output
to blow the I/U Fuse. Once the I/U Fuse is blown, the I/U Set signals are no longer output.
This means that the starter setup sequence and ATDC Sensor automatic adjustment will
not be carried out when the Power Switch is thereafter turned ON.
