摘要： A system for cooling an inkjet print head with the print head having a nozzle plate and heater chip. The nozzle plate contains a series of firing chambers and nozzles. The heater chip contains several heating elements and cooling channels. Ink is heated in the firing chambers and forced through the nozzles onto paper. A pump is employed to pump the ink from an ink reservoir through the cooling channels in the heater chip in order to maintain the heater chip at a constant temperature. When the printer is actively printing, at least a portion of the ink is returned to the reservoir. When the printer is not actively printing, ink is still pumped through the cooling channels to maintain the heater chip at the proper temperature.

摘要： An integrated nozzle plate having a heater chip and nozzles, firing chambers and channels formed from several layers of resist material affixed to the heater chip. The nozzles, firing chambers and channels are formed in the resist material using a photolithographic method. The photolithographic method involves placing a negative resist layer directly on a silicon wafer heater chip. A protective layer is then placed on top of the negative resist layer to act as a mask. A positive resist layer is then placed on top of the protective layer. A first mask is placed on the positive resist layer. The integrated nozzle plate is then exposed to ultraviolet light and the positive resist layer is developed. The protective layer not covered by the positive resist layer is removed and a second negative resist layer is deposited thereon. A second mask is placed on the second negative resist layer. The first and second negative resist layers are exposed to ultraviolet light and the negative resist layers are developed. The resulting integrated nozzle plate is then mounted to a print head, connected to an ink reservoir and placed in an inkjet printer for use.
