RFID Chip
(Y)
Antenna Board
Each toner bottle has a chip.
This chip contains data on the amount of toner consumed from the
bottle, and is used for toner bottle detection (the machine uses it to
detect if the bottle installed or not).
It sends its data to the RFID antenna board.
There is no electrical contact. The data is sent by wireless
communication.
