6-2. Toner Recycling
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 (1) receives drive through a
gear at the rear end of the PC Drum.
The gear on Toner Recycling Coil 1 receives drive through a gear at the rear end
of the PC Drum. While, the gear on Toner Recycling Coil 2 receivesdrive through

6-3. IU Fuse F1
The Imaging Unit is provided with a fuse called IU Fuse F1. When a new Imaging
Unit is installed in the copier and the Power Switch turned ON, an IU 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 IU Fuse Blow signal
is output to blow F1. Once F1 is blown, the IU 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.
