Printing Process
The Phaser 6180 Printer print process consists of the following steps:
1. Charging – The Drum surfaces are charged with electricity.
2. Exposure – The Drums are exposed to laser beams.
3. Development – Image is developed with toner.
4. Transfer (Drum ---> Paper) – Four color finished toner image on the
Drums is transferred onto the paper.
5. Cleaning (Print Cartridge) – Remaining toner on the drums is collected.

the Belt.
