Image-formation system
The image-formation system forms a toner image on media. The product includes four print cartridges
that contain the toner that is used to create the image on the media. Toner is applied in the following
order, using only the colors necessary for a specific image: yellow (Y), magenta (M), cyan (C), and black
(Bk).

Image-formation process
Laser printing requires the interaction of several different technologies including electronics, optics, and
electrographics to provide a printed page. Each process functions independently and must be
coordinated with the other processes. Image formation consists of the following processes:
●
Latent-image formation
●
Development
●
Transfer
●
Fuser
●
ITB cleaning
●
Drum cleaning
