摘要： Apparatus and method for refilling print cartridges for computer controlled printers. The apparatus creates a closed system that is isolated from ambient pressure. The apparatus utilizes both a vacuum in the ink reservoir in the print cartridge and vertical displacement of the refill reservoir with respect to the reservoir in the print cartridge to draw refill ink into the print cartridge to an operating level and to an operating pressure of less than ambient pressure. Within this closed system the apparatus dislodges the closure on the print cartridge and reseats a replacement closure during refilling.
