ABSTRACT:
A thermal ink jet head is disclosed in which the jetting resistors, fluid interconnections, ink reservoir, electrical connections, and jetting orifices are fully integrated to provide an inexpensive, disposable jetting head. The entire hydraulic ink system is sealed to eliminate user interaction with the liquid ink, and ink can only exit the head via the jetting orifices under the influence of the jetting resistors. Once the ink is expended the user disposes with the old head and installs a new one by breaking and making a simple mechanical and low voltage electrical connection.
