12. Developing section
B. Developing section/Y, M, C drive mechanism
• Drive force from the color PC motor is transmitted to the color dev. unit engaged motor so
that the developing section/Y, M, C is driven.
• When the color dev. unit engaged motor starts running, the color dev. unit engaged gear
is engaged with the color dev. unit drive transmission gear and the drive force of the color
PC motor is transmitted to the developing section/Y, M, C.
• The state of the coupling operated by the color dev. unit engaged motor is detected by
the color dev. unit engaged position sensor.
