13.3 Functions

(1)Revolver motor

The revolver unit rotates with the drive of the revolver motor (two-phase stepping motor). The revolver home position sensor detects its home position.

(2)Developer motor drive unit

The developer motor 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 and the color toner supply clutch. Only the color developer unit at the developing position is driven by this motor.

(3)Color toner cartridge

The color toner cartridge and the color developer units are fitting each other to prevent misinstallation of the color toner cartridge. Therefore, the revolver unit has no device preventing misinstallation.

(4)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.

(5)Color toner cartridge sensor

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 cartridge is detected at the toner cartridge replacement position.

(6)Revolver home position sensor

This sensor is a transmissive type light sensor detecting the revolver unit home position. The position detection is performed at initialization. "Call for service" if it does not detect the position in a specified period of time.
