Figure 5 Toner Cartridge and Cartridge Housing
A piezo electric Low Toner Sensor located under the shutt
er opening monitors the level of toner
in the Toner Cartridge Housing.
The IOT CPU PWBA samples the Low Toner Sensor status every 0.1 second while the
machi
ne is making and moving the Developer out of the Toner Cartridge Housing into the con-
veyor. When a low developer level is detected 5 times in succession, the Toner Cartridge Motor
is
ener
gized for 10 seconds. This moves additional developer from the Toner Cartridge to the
Toner Cartridge Housing.
When a low developer level is detected 20 times in succession or for longer than 25 seconds, a
“low toner”
message is displayed. If the Toner Cartridge is replaced, the “low toner” message is
removed as soon as a low toner level is no longer detected by the sensor 10 times in succes-
sion.
If 100 seconds of “low toner” is sensed while the Toner Dispense Motor is running, then the
cont
rols wi
ll not allow another copy job to be stated. At the end of the current job, a “do not
copy” message is displayed and the copier will not start another job.
Conveyer Auger
The 4 toner Cartridge Housings are different distances f
rom the Rotary Dispenser. For that
reason, there are different lengths of Conveyor Augers and one Cartridge Housing (Y) does not
use a Conveyor Auger. Refer to Figure 6.
The Conveyor Augers are
driven by t
he Dispense Motors. The Dispense Motors are energized
when the IOT CPU PWBA senses low reflective readings from the ADC Sensor for the patch
on the IBT.
Figure 6 Developer Distribution Path
Rotary Dispenser
The Rotary Dispenser accepts the four different developer
s and deposits them into their appro-
priate Developer Housing Assembly within the Developer Rotary. Figure 7
shows the Rotary
Assembly for one color system.
As toner is deposited into the Rotary Dispenser by the Conveyor A
uger, it is transported out to
the Developer Housing Assembly by a Rotary Auger.
The Rotary Augers have a Axel shaft that goes to
the back side of the Developer Housing
Assembly. This shaft has a gear that is driven whenever the Developer Clutch is energized and
is powered by the Main Drive. The Rotary Auger rotates at 345 rpm to move the toner quickly
from the Rotary Dispenser to the Developer Housing Assembly.
