Patent abstract
In the process of refilling a consumed inkjet printer cartridge, the nozzle and the internal ink carrier medium are cleaned by applying steam under pressure in short burst intervals at the nozzle. The dissolved ink remnant in the cartridge is extracted by a suction device applied over the nozzle. The completely cleaned cartridge is refilled by injecting fresh ink through a refill opening formed in the cartridge casing at a location directly opposite to the nozzle.
