Monochrome/Color Switching Mechanism - Toshiba e-STUDIO 2555C Service Manual

Monochrome/color switching mechanism

The feeding/developing drive unit is driven by the paper feeding/developer unit drive motor to drive the
developer unit and the paper feeding section.
Switching of the monochrome and color modes is performed by the monochrome/color switching unit.
In the monochrome mode, the switching plate is positioned at "A" in the figure below and the
monochrome/color switching sensor (S11) is OFF.
At this time, the drive gears of the drum and the developer unit are not engaged. (Monochrome mode
operation)
When the mono/color switching motor (M3) starts rotating, the switching plate is moved and the
monochrome/color switching sensor (S11) is turned ON.
The coupling cam is rotated with a movement of the switching plate and then the idling gear and the
color drive gear are engaged.
Thus the rotation of the motor is transmitted to each gear in the color drive gear rows.
