Engine control system

The engine control system coordinates all printer functions and drives the other three systems.

The engine control system contains the DC controller, high-voltage power-supply PCA, low-voltage power-supply unit, and fuser control.

Laser/scanner system

The formatter sends video signals to the DC controller, which controls the laser/scanner. When the laser/scanner system receives those signals, it converts them to latent images on the photosensitive drum.

Laser failure detection

The optical unit failure detection sensor manages the laser/scanner unit failure-detection functions. The DC controller identifies the laser/scanner unit failure and notifies the formatter if the laser/scanner unit encounters the following conditions:

●Scanner motor failure

●BD failure

Image-formation system

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