(1)The main motor will drive gear (4) through the interconnection of other gears.
(2)When gear (4) is rotated, rib A on that gear will push against the new toner actuator; the new toner sensor will detect the actuator motion, and the toner sensor detects that a new toner cartridge has been installed.
(3)The standard toner cartridge has Rib A and Rib B on gear (4).
When the toner actuator is pushed twice, the two signals that are generated by the new toner sensor, tell the machine that a standard toner cartridge has been installed.
(4)The high yield toner cartridge only has Rib A on gear (4).
When the toner actuator is pushed once, the signal that is generated by the new toner sensor, tell the machine that a high yield toner cartridge has been installed.
