摘要： A mounting assembly is described for mounting and housing printhead modules. The mounting assembly includes a lower plate, an upper plate and multiple mounting blocks. The lower plate can include openings configured to expose a surface of a printhead module housed within the mounting assembly, the surface including multiple ink nozzle openings. Each opening can include alignment datums to align the printhead module in a first direction and in a second direction. The upper plate is approximately parallel to the lower plate, and can include multiple openings configured to provide access to ink channels formed in printhead modules housed within the mounting assembly. The mounting blocks are positioned between and affixed to the lower and upper plates, and are configured to couple to a printhead module. Each mounting block can include a datum to align the printhead module in a third direction.

摘要： A fluid droplet ejection device including a body defining a plurality of fluid paths that each include an inlet including a flow restriction, a pumping chamber, and a nozzle opening communicating with the pumping chamber for discharging fluid droplets. An actuator is associated with each pumping chamber. The pumping chamber has a largest dimension that is sufficiently short and the flow restriction provides sufficient flow resistance so as to provide a fluid droplet velocity and/or volume versus frequency response that varies by less than plus or minus 25% over a droplet frequency range of 0 to 40 kHz. Also disclosed are fluid droplet ejection devices in which the ratio of the inlet flow resistance to the pumping chamber flow impedance is between 0.15 and 0.9, the pumping chamber has a time constant for decay of a pressure wave in the pumping chamber that is less than 25 microseconds.

摘要： In the particular embodiments described in the specification, a thin-film transducer ink jet head is prepared by oxidizing one surface of a silicon wafer (10) to provide a dielectric layer (11), forming electrodes (17) on the layer by photoresist processing techniques, depositing one or more layers of PZT material to provide a thin-film piezoelectric layer (18) having a thickness in the range of 1-25 microns, forming another pattern of electrodes (24) on the surface of the PZT layer by photoresist techniques, and selectively etching the silicon substrate in the region of the electrodes to provide an ink chamber (30). Thereafter, an orifice plate is affixed to the substrate to enclose the ink chambers and provide an ink orifice for each of the chambers. An ink jet head having chambers 3.34 mm long by 0.17 mm wide by 0.15 mm deep and orifices spaced by 0.305 mm is provided.

摘要： In the particular embodiments of the invention described in the specification, an opaque subtractive color ink reflection print having improved color purity resulting from reduced frosting and crystallization of the ink layers is prepared by reheating the ink image to a temperature above the melting point of at least one of the inks and then quenching the image by cooling it at a rate of the least 50 DEG C per second. In one embodiment, the ink image is produced by an ink jet head (10) applied to a substrate (14) supported on a platen (15) maintained at least 20 DEG C below the melting point of the inks to inhibit spreading of the inks into the substrate, and the image is thereafter heated by a heater (28) to a temperature at least 20 DEG C above the melting point of at least one of the inks for a period of 3 to 5 seconds and then quenched by a quenching platen (32) at a rate of 500 DEG C per second to produce an image having less than 20 % light loss resulting from scattering of light by frosting and crystallization of the ink in the layers.
