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 the other printer processes. Image formation consists of six processes:

∙Step 1. Drum Cleaning

∙Step 2. Drum Conditioning

∙Step 3. Image Writing

∙Step 4. Image Developing

∙Step 5. Image Transferring

∙Step 6. Image Fusing
