    摘要: In a technique for obscuring the stitch error perceived the eye of a viewer, a first plurality of drops of fluid are ejected in a first firing sequence at a medium in a first swath from a print head including at least one die having a plurality of nozzles while moving in a first direction relative to the medium. Thereafter, the medium is advanced in a second direction substantially perpendicular to the first direction. The print head is again moved in the first direction and a second plurality of drops of the fluid are fired at the medium in a second swath adjacent the first swath. A controller randomly modulates the spot size resulting from the drops of the fluid. The stitch error may be a misplacement of the second swath relative to the first swath and the second plurality of drops includes a random variety of drop sizes.

    摘要: A printhead and method of fabrication thereof provides that the printhead reservoir has substantially the same cross-sectional ink flow area as the total cross-sectional area of the plurality of individual ink channels which interconnect the reservoir with the printhead nozzles. Since the flow area of the reservoir is substantially matched to the total flow area of the channels, the ink capacity of the reservoir is relatively low and the flow rate therethrough during a printing operation is relatively high. The small capacity of reservoir, together with the high ink flow rate therethrough, assures short ink residency time during printing, so that any exsolved air bubbles in the ink are swept away with subsequent ink droplet ejections during a printing operation and thus prevents any air bubbles present from coalescing into larger bubbles which can cause print quality defects.

    摘要: The nucleation efficiency of a thermal ink jet printhead is improved by forming a heater element with a planar surface. A heater resistor, polysilicon in a preferred embodiment, has an irregular surface which can trap gas or vapors in the cracks or crevices. When the heater resistor is pulsed, the nucleation temperature is reduced by these trapped vapors requiring an increase in electrical input to the resistors, thereby reducing efficiency. The invention recognizes that a heater resistor with a planar surface in contact with an ink layer results in a higher nucleation temperature and increased efficiency. In one embodiment, a phosphosilicate glass (PSG) is flowed directly onto the resistor surface forming a planarization layer. Subsequent deposition of tantalum substantially replicates the underlying topography creating a heater resistor with a smooth surface adjacent the ink.In a second embodiment, a diffusion layer which is conformal is formed on the resistor surface with the PSG layer formed on the oxide layer. The diffusion layer can be a pyrolytic CVD deposited silicon nitride or a thermally grown oxide layer. The PSG layer has a planarized surface to which the tantalum conforms.

    摘要: An ink jet printer is configured in a hybrid architecture wherein a full width printbar is combined with a partial width color scanning assembly to provide the capability of selectively printing in black only or, alternately, of producing color prints by operating the color scan assembly exclusively. The cost of the hybrid system, when compared to a full width color system using four full width printbars, is greatly reduced. Throughput time is reduced by providing the control circuitry for distinguishing between black only and color operation and selectively controlling the printer mode of operation. The hybrid architecture is particularly useful in a LAN system since it provides a mechanism for balancing the relative color versus black page decomposition speed limitations. Also, the hybrid architecture enables a relatively simple implementation of a checkerboarding technique to suppress banding in output prints.

    摘要: An improved ink jet printhead including a channel plate and a heater plate having an improved flatness top bonding surface. The heater plate includes a silicon wafer base, a first insulating layer formed on the wafer base, and at least an intermediate component sublayer formed over the first insulating layer. The heater plate also includes a second insulating layer formed over the at least intermediate component sublayer, and having a top bonding surface for bonding the: heater plate to the channel plate. To substantially improve flatness of the top bonding surface of the second insulating layer, the component sublayer includes active thin film layer patterns in circuit areas of the thin sublayer, and non-active relief compensating patterns in non-circuit areas thereof. The non-active relief-compensating patterns each have a thickness substantially equal to the thickness of the active thin film patterns in the circuit areas of the sublayer.

    摘要: A full width read and/or write assemblies, such as a full width thermal ink jet printbar, is disclosed, having materials with both a high thermal coefficient of expansion and a low thermal coefficient of expansion. A suitable adhesive which provides lateral give while firmly holding the respective components together provides dimensional stability to the printbar element having a low thermal coefficient of expansion when components having high thermal coefficient of expansion are assembled thereto. The flexible or floating mounting enabled by lateral give of the adhesive allows for the application of cost effective materials with a high thermal coefficient of expansion to be used for support functions such as, for example, circuit boards and ink manifolds. The flexible or floating mounting relieves shear stress cased by a differential in the expansion or contraction of materials having a different thermal coefficient of expansion. Since the thermal expansion of the various components expand and contract from a center location thereof, this center location is bonded by an adhesive which does not provide lateral give, so that alignment between parts are maintained while the remainder of the respective components float relative to each other and prevent thermally induced stresses which tend to cause warpage.
