Abstract
A method of sealing a nozzle. First, a device comprising a chamber, a nozzle, and a nozzle plate is provided, wherein the nozzle plate is installed on the chamber and the nozzle passes through the nozzle plate and connects the chamber. The chamber is then filled with ink. Residual ink on the nozzle plate is then removed by water. After that the nozzle plate is dried, a solution is then coated on the nozzle plate, wherein the solution has higher surface tension than the ink and has smaller contact angle with the nozzle plate than the water. Next, the nozzle plate is dried. Finally, a flexible material is bonded on the nozzle plate to seal the nozzle.
