Printer Controls
Print-Quality Modes
There are four print-quality modes:
Color Registration Control
The printer uses a single-pass, quad system where each color (Yellow, Magenta,
Cyan, and Black) has its own imaging drum. Images are formed on the drums, in the
respective colors, and then layered on the media to form one image. To monitor color
registration, photo-reflective, Color Registration Sensors are mounted inside the
Registration Sensor Assembly. These sensors are positioned at the front and rear
edges of the Transfer Unit belt as shown in the following figure.
Print-Quality Mode Description

type. For example, Photo print-quality mode is used when printing on
Glossy Paper and Standard print-quality mode is used when printing
on Plain Paper. (This setting is only available in the printer driver.)
