Phaser 6125/6130 Color Laser Printer Service Manual 2-29
Theory of Operation
The drive path is changed by the Color Mode Switching Solenoid in the
Feed Drive Assy to allow drive from the Main Drive Assy to reach only the
Black Developer. This is done to ensure that the Sub Drive Assembly
cannot rotate the Yellow, Magenta, and Cyan Developers during B/W
printing.
The Color Mode Switching Sensor detects whether the drive path is set
for B/W or full color.
