Toner cartridge
A major portion of the image-formation system is contained in the toner cartridge, as shown in
the figure below.
The toner cartridge is the core 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, waste 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 cartridge drive system that minimizes banding.
