2.1 Print Process
This printer is a "Full color page printer" that uses the principle of
electrophotographic recording. Each YMCK color (yellow, magenta, cyan,
black) has its own special drum (Photoconductor (PC) drum) and developer
that are used in tandem. Since each color is developed simultaneously, the
color image can be printed at high speed comparing to the four cycles engine
printer. The transfer intermediate is coordinated, and at the end of the process
the layered color toner images produce a full color print. The major steps of the
print process are described below.
1. Charging: The PC Drum surfaces are charged with electricity.
2. Exposure: Image areas are exposed on PC Drum with laser radiation.
3. Developing: Image areas on drums are developed with toner.
4. Primary transfer: The toner image on PC Drum is transferred to Intermediate
Transfer Belt.
5. Cleaning: PC Drum are cleaned.
6. Secondary transfer: The complete four-color toner image on the Intermediate
Transfer Belt is transferred to the paper.
7. Electrical discharge:The electrical charge of the paper is discharged.
8. Cleaning: Intermediate Transfer Belt are cleaned.
9. Fusing: Toner on the paper is fused with heat and pressure.
