Ricoh A66 - Toner Cartridge Detection

6.2.7 Toner Cartridge Detection
This machine has two toner cartridge sensors to detect the presence of the
toner cartridges.
(1) Bk Toner Cartridge Detection
When a Bk toner cartridge [A] is installed in the center of the development
unit, the hook [B] on the Bk toner cartridge pushes the sensor actuator [C],
into the BK toner cartridge sensor [D] and the machine detects that a toner
cartridge has been installed. The sensor only actuates when the revolver is
at home position.
