FCC WARNING Changes or modifications not expressly approved by the party responsible for compliance could void the user's authority to operate the equipment. NOTICE This equipment has been tested and found to comply with the limits for a Class B digital device, pursuant to part 15 of the FCC Rules. These limits are designed to provide reasonable protection against harmful interference in a residential installation. This equipment generates, uses and can radiate radio frequency energy and, if not installed and used in accordance with the instructions, may cause harmful interference to radio communications. However, there is no guarantee that interference will not occur in a particular installation. If this equipment does cause harmful interference to radio or television reception, which can be determined by turning the equipment off and on, the user is encouraged to try to correct the interference by one or more of the following measures: -Reorient or relocate the receiving antenna -Increase the separation between the equipment and receiver. -Connect the equipment into an outlet on a circuit different from that to which the receiver is connected. -Consult the dealer or an experienced radio/TV technician for help. 4465872A Toner cartridges and image drum units set area Printer base unit A toner cartridge and image drum unit are equipped with RF-ID TAG. If toner cartridges and image drum units are set to a printer, communication of RF-ID TAG and a RFID read writer module (4465872A) will be attained. The function of this system is the following. -Management of the existence detection and toner residual quantity of a toner cartridge and image drum unit Toner cartridge RF-ID TAG × 2 Image drum unit
