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： A heater chip module is provided comprising a rigid carrier, a nozzle plate and a heater chip. The carrier is adapted to be secured to a container for receiving ink. The carrier includes an opening extending completely through the carrier. The opening has an outer periphery. A nozzle plate is coupled to the carrier and extends out beyond the outer periphery of the opening so as to substantially cover the opening. A heater chip is positioned within the opening and is coupled directly to the nozzle plate. The heater chip is coupled to the carrier only by way of the nozzle plate. Thus, the heater chip does not directly contact the carrier.

摘要： Cleaning roller (7) contacts intermediate transfer roller (4), each rotating at the same surface speed to avoid rubbing. The cleaning roller has an electric potential sufficient to remove toner from the transfer roller to clean it. Silicone oil is applied by a roller 29, which is wetted by oil from a oil impregnated wiper (31). The oil facilitates cleaning and reduces wear of the intermediate transfer roller, which is typically soft to facilitate transfer.

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.
