9.3.6 Printing Originals Containing a Color Page

When making copies/prints of originals containing a color page, the machine uses the following sequence to avoid
a drop in productivity:
color original:
monochrome original:
MEMO:
A switch-over from full-color mode to monochrome mode requires a sequence in which the high voltage of YMC
must be lowered. By reducing the use of such a sequence, the machine avoids an appreciable drop in productivity.
9.3.7 Driving and Controlling the Image Formation System and the
High-Voltage System
Drive Control
The image formation system is driven by the toner container motor, developing motor, and drum ITB motor
through gears. (For details, see the appropriate sections.)
