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.

6-3. I/U Fuse F4
The Imaging Unit is provided with a fuse called I/U Fuse F4. 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 F4. Once F4 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.
