Toner Cartridge - Ricoh B230 Service Manual

6.7.3 TONER CARTRIDGE

RFID (Radio Frequency ID)
Each toner cartridge of this machine has a RFID chip [A]. This stores the total "on" time of
the toner supply clutch. This is used to calculate the amount of toner remaining in the toner
cartridge. The chip is also used to detect whether the cartridge is installed (if the cartridge
is not installed, the machine does not detect a signal from the memory chip).
The RFID transmits its data to the RFID antenna board [B] without any contact.
