Toner Cartridge
Figure 5-10 Toner Cartridge
A major portion of the Image Formation System is contained in the
Cartridge as shown in the figure above.
The Toner Cartridge is the “heart” of the Image Formation System. It
houses the cleaning, conditioning, and developing steps of the
process. The Toner Cartridge contains the photosensitive Drum,
primary charging roller, developing station, Toner cavity, and cleaning
station. Including these components that wear, degrade, or are
consumed in the replaceable Toner Cartridge eliminates the need for
a service call when replacement is required.
The printer also has a new Cartridge drive system that minimizes
banding, with more constant paper speed.
