Toner Cartridge
Each Toner Cartridge has an Agitator driven by a unique Cartridge Motor. The Agitator serves
two functions; it prevents the developer from becoming compacted, and it moves the developer
to the outlet port where it falls through to the Toner Cartridge Housing. This Cartridge port
shutter closes when the Toner Cartridge is rotated for removal from the machine. Each Toner
Cartridge holds a mixture of toner and carrier beads.
Table 2 show the composition by weight
for each developer that are within the new Toner Cartridges.
The Cartridge Motors is powered by 24 VDC derived from Interlocked +24 VDC and controlled
by enable signals from the IOT Drive PWBA. When the Low Toner Sensor in the Toner Car-
tridge Housing is activated, the Cartridge Motor runs for:
• 10 second intervals when the machine is actively making prints.
• 20 second intervals when the Low Toner Sensor senses low toner levels and when
machine power is on and the front Door Interlock is closed.
Toner Cartridge Housing
The Toner Cartridge Housing contains:
• Agitator
• Auger
• Paddle
• Low Toner Sensor (Piezo type, located outside the Toner Cartridge Housing unit)
The agitator and paddle help prevent the developer from becoming compacted. The auger
moves the developer to the outlet where the developer falls into the conveyor. These compo-
nents are driven by a Toner Dispense Motor, one motor for each of the four colors. This motor
also drives a Conveyor Auger for transporting the developer out of the Toner Cartridge Hous-
ing.
