Latest Patents

Sasada's latest patents include an advanced ink jet printer that ensures high-quality printing with minimal ink contact with the atmosphere. This printer features a unique design where the ink jet recording heads and sub tanks are mounted at the side of the Y cursor, while the main tanks are positioned at the side of the printer body. Upon completion of printing or during standby, the ink in the sub tanks is recovered to the main tanks, and the ink in the recording heads is directed to a waste solution tank. Before supplying ink from the main tanks to the sub tanks, the ink is stirred to maintain its quality. Additionally, the recording heads are cleaned with a cleaning solution, and air is supplied to dry them. An atmosphere release valve is incorporated to prevent ink evaporation during non-printing periods.
