6.9.3 TONER CARTRIDGE
[A]: Shutter pin
[B]: Toner supply port plug
[C]: Toner supply port
[D]: ID chip
Each toner cartridge is installed in a bin of the toner hopper.
When the bin door is closed, a shutter pin [A] forces open a plug [B]. This opens
the toner supply port [C] and toner can flow from the cartridge.
When the cartridge is removed from the machine, the plug [B] moves to its original
position and covers the toner supply port of the toner cartridge. This prevents toner
leakage from the bottom of the toner cartridge (STC) when the toner cartridge
(STC) is removed.
The sides of a toner cartridge gradually collapse as toner is pulled out of the
cartridge by the toner pump.
The built-in ID chip [D] near the toner supply port holds information about the color
and type of toner, the location of the factory where it was produced, and other
information.
