DC Controller/power system
The DC Controller PCA coordinates all print engine activities, drives the laser, and coordinates print data from the Formatter PCA with the image formation process. The DC Controller also includes both AC and DC power supply and distribution circuitry. The DC Controller controls the following systems and functions:
lPrint Engine Control
•Laser and Scanner Drive
•Paper Motion Photosensors (Paper Out, Paper Registration, and Paper Exit Sensors)
•Motor
lPower System
•AC Power Distribution
•DC Power Distribution
•Overcurrent/Undervoltage Protection
•SleepMode
•High Voltage Power Distribution
