13.3 Functions

1) Revolver motor (M12)
The revolver unit rotates with the drive of the revolver motor (M12) (two-phase stepping motor). The
revolver home position sensor (S8) detects its home position.
2) Developer motor drive unit
The developer motor (M11) drives the color developer unit and the toner supply auger in the revolver
unit. This drive is connected and disconnected by the color developer unit drive clutch (CLT9) and
the color developer toner supply clutch (CLT8). Only the color developer unit at the developing posi-
tion is driven by this motor.
3) Color developer unit
The color developer units must be in the revolver unit to perform color development. Since the
revolver unit has no device to detect misinstallation, be careful not to install the wrong unit. Refer to
Chapter 12 for details.
4) Color toner cartridge sensor (S9)
This sensor detects the installation fault of the color toner cartridge. It is an optical reflection sensor
detecting the installation fault with the reflecting light from the reflection section. The color toner car-
tridge is detected at the toner cartridge replacement position.
5) Revolver home position sensor (S8)
This sensor is a transmissive type light sensor detecting the revolver unit home position. The posi-
tion detection is performed at initialization. "Call for service" if it does not detect the position in a
specified period of time.
