3.2.4.2 New toner detection mechanism
(1) The motor drive is transmitted to the gear (4) through a few gears.
(2) When the gear (4) is rotated, the rib A on the gear (4) pushes against a new toner actuator, and
a new toner sensor detects the actuator motion. Then, the toner sensor detects that a new toner
cartridge is 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.
