摘要： An apparatus and related method for automatically aligning one or more print head modules in an ink jet printing system are provided. A mounting supports and aligns a print head module with respect to three axes of movement. The mounting includes rotatable cams that contact control surfaces connected to the print head module to move the print head module in a desired direction. The related method automatically positions multiple stationary print heads with respect to three axes of movement, including rotational adjustment about a Z-axis. The method also automatically adjusts the position of a single print head with respect to its angular rotation about the Z-axis.

摘要： An apparatus and method provide on-demand drop volume modulation by utilizing a single transducer driving waveform to drive an ink jet. The driving waveform includes at least a first portion and a second portion that each excites a different modal resonance of ink in an ink jet orifice to produce ink drops having different volumes. A control signal is applied to the driving waveform to actuate the selected portion of the waveform to eject the desired ink drop volume for a given pixel. The control signal also cancels the non-selected portion(s) of the waveform to avoid extraneous excitation of the transducer.

摘要： An apparatus and related method for high speed offset ink jet printing are provided. Multiple print head modules form a full width ink image by ejecting ink drops onto an intermediate transfer surface on a rotating drum. One or more complete images are formed on the intermediate transfer surface in less than one revolution of the drum. The images are then transferred to a final receiving medium while additional images are simultaneously formed on the intermediate transfer surface as the drum continues to rotate. Two or more color component images may be overlayed to form a complete color image in less than one revolution of the drum. Additionally, the simultaneous imaging and image transfer allow the apparatus and method to print images having a length greater than the circumference of the drum.

摘要： An apparatus and related method for improved image fusing in an ink jet printing system are provided. An ink image is transferred to a final receiving substrate by passing the substrate through a transfer nip. The substrate and ink image are then passed through a fusing nip that fuses the ink image into the final receiving substrate. Utilizing separate image transfer and image fusing operations allows improved image fusing and faster print speeds. The secondary fusing operation enables the image transfer process to use reduced pressures, whereby the load on the drum and transfer roller is reduced. Additionally, the secondary fusing operation may be utilized to apply a supplemental coating to the transferred image.

摘要： An ink jet (10) apparatus and method provides high-resolution gray scale printing by providing multiple PZT drive waveforms (100, 110, 120), each having a spectral energy distribution that excites a different modal resonance of ink in an ink jet print head orifice (14). By selecting the particular drive waveform that concentrates spectral energy at frequencies associated with a desired oscillation mode and that suppresses energy at the other oscillation modes, an ink drop (170, 180, 190) is ejected that has a diameter proportional to a center excursion size of the selected meniscus surface oscillation mode. The center excursion size of high order oscillation modes is substantially smaller than the orifice diameter, thereby causing ejection of ink drops smaller than the orifice diameter. Conventional orifice manufacturing techniques may be used because a specific orifice diameter is not required. Jetting reliability and contaminant susceptibility are, thereby, improved by eliminating the need for an unconventionally small orifice. Changing a selected PZT drive waveform amplitude changes drop ejection velocity without changing drop volume. This invention, therefore, provides for selection of ejected ink drop volumes having substantially the same ejection velocity over a wide range of ejection repetition rates.

摘要： Gray scale ink jet printing method and apparatus produce a high quality image having varying color intensities. This is achieved by mixing a colored phase change ink with varying amounts of a clear phase change ink base, thereby producing multiple gray scale levels of each color. The mixing either can be performed prior to placement of the phase change ink in the printer, or can be performed within the printer to produce different levels of color intensity during the printing process.

摘要： A particulate filter (16) is provided within an inlet channel (22) of an ink jet (14). The filter is oriented generally in the direction of ink flow to provide a greater filter surface area. Positioning the filter within the inlet channel results in reduced acoustic crosstalk, more effective filtering, and more efficient purging of the filter itself because of the relatively high ink pressure drop across the filter in the channel. Positioning the channel vertically assists the buoyancy of the bubble movement during operation and purging.

摘要： An improved ink jet print head includes tapered manifolds (222), ports (234), and inlet channels (214) all leading elevationally upward to sweep bubbles from the head, aided by their buoyancy. The ports opening to the inlet channels are distributed at staggered locations throughout the manifolds with at least some of the ports located adjacent to the elevationally highest edge of each manifold. This aspect of the invention reduces bubble entrapment and improves jetting performance by reducing acoustic cross-talk among ink pressure chambers (204) of the head. Moreover, tapering the ink supply manifolds and other features causes more uniform ink flow rates and reduces flow rate stagnation regions within the head. Purging cycles therefore require smaller volumes of ink than with prior designs.

摘要： An ink jet print head (10) has a supply channel (14, 24, 52) connecting an ink source with an upper manifold (60U) and a lower manifold (60L). Each manifold has a tapered structure. From each manifold multiple inlet channels (36, 34, 44, 54) each lead to a respective pressure chamber (28) from which an outlet channel (40, 38, 46, 56, 62, 76, 82) leads to nozzles (88) from which droplets of liquid ink are expelled as a result of the action of a pressure transducer on the pressure chamber. Each manifold is separated from the supply channel by a baffle structure (92) that includes three baffles (94) formed by alternating plates (64, 78) having an open manifold with plates (58, 72) having a blocked manifold. The baffle structure reduces jetting nonuniformity by damping pressure displacement waves in the ink caused by the expulsion of ink droplets. The baffle structure also promotes effective heat transfer from the print head to ink being drawn in to the print head from the ink source. The print head is operated by drawing ink from the supply channel through the baffle structure to replace ink drawn from the manifold as a result of expulsion of ink from the nozzles.

摘要： An ink jet (10, 200) provides high-resolution gray scale printing or switchable resolution printing by providing PZT drive waveforms (100, 110, 120, 360, 370), each having a spectral energy distribution that excites a modal resonance of ink in an ink jet print head orifice (14, 208). By selecting the particular drive waveform with selectable energy inputs that concentrates spectral energy at frequencies associated with a desired oscillation mode and that suppresses energy at the other oscillation modes, an ink drop (170, 180, 190, 210) is ejected that has a diameter proportional to a center excursion size of the selected meniscus surface oscillation mode. The center excursion size of high order oscillation modes is substantially smaller than the orifice diameter, thereby causing ejection of ink drops smaller than the orifice diameter. Conventional orifice manufacturing techniques may be used because a specific orifice diameter is not required. Jetting reliability and contaminant susceptibility are, thereby, improved by eliminating the need for an unconventionally small orifice. Changing a selected PZT drive waveform amplitude changes drop ejection velocity without substantially changing drop volume. This invention, therefore, provides for selection of ejected ink drop volumes having substantially the same ejection velocity over a wide range of drop ejection repetition rates.
