Functional Overview
Image Formation System
Image Formation System
Laser printing requires the interaction of several different
technologies (such as electronics, optics, and electrophotographics)
to provide a printed page. Each process functions independently
and must be coordinated with all other printer processes. The
image formation process consists of six stages:
1. Cleaning
4. Developing
2. Conditioning
5. Transferring
3. Writing
6. Fusing
The toner cartridge houses the cleaning, conditioning, and
developing stages of the process. Components of the image
formation system that wear, degrade, or are consumed are built
into the replaceable cartridge. The toner cartridge contains the
photosensitive drum, primary charging roller, developing station,
toner cavity, and cleaning station. This eliminates the need for a
service call when replacement is required.
