One of her latest patents involves an advanced ink jet printer design. This printer supplies ink from a main tank located outside the carriage, ensuring stable ink supply without leakage. The system utilizes an ink level sensor to detect when the ink level in a second ink chamber drops below a predetermined position. At this point, pipes are inserted into slit valves in the second ink chamber. By operating a pump, air is discharged from the chamber, creating a negative pressure that allows ink to flow from the main tank into the chamber. This innovative approach effectively prevents ink leakage during the supply process.
