    摘要: Imaging apparatus includes a printhead with one or more nozzles, wherein heaters are positioned proximate to the nozzles. Electrical activation of the heaters creates ink droplets having a plurality of volumes. The use of higher-energy pulses in the portion of the waveform of heater activation associated with the formation of small drops results in more constant relative drop velocities and consequently, improved image quality. The printing apparatus also contains a droplet deflector having a gas source positioned at an angle with respect to the stream of droplets thereby separating ink droplets having one of the plurality of volumes from ink droplets having another of the plurality of volumes. An ink guttering structure is provided for capturing one range of ink-drop volumes, while allowing another volume range to strike an image receiver.

    摘要: Methods of printing a desired color image on a printing medium by construction from individual ink drops deposited in pixel arrays includes passing a multiple-nozzle ink-discharging pen or an odd number of staggered pen cartridges across the medium multiple times, each pass creating a portion of a respective segment of the image, and periodically advancing the medium so that portions of successively different segments are created by the pen(s). During each pass, the “portion-creating” function includes discharging from the pen(s) an odd submultiple of the full density of ink desired in the segment of the desired image that is being created, so that printing full density in each segment requires an odd number of passes. The medium is advanced by an odd submultiple of the height of the segment being created in each pass and is preferably advanced after each pass of the pen(s). The portion-creating includes creation by the pen(s) of a multiplicity of spaced-apart diagonal lines. Preferably in each passing step after a first one, the diagonal lines are created in positions such as to at least partially fill in unprinted spaces between previously created diagonal lines. Preferably the diagonal lines are all at a substantially common angle (ideally forty-five degrees) to a pen-scanning direction.

    摘要: An apparatus for printing an image is provided. In this apparatus, each nozzle is operable to selectively create a stream of ink droplets having a plurality of volumes. The apparatus also includes a droplet deflector having a gas source. The gas source is positioned at an angle with respect to the stream of ink droplets and is operable to interact with the stream of ink droplets thereby separating ink droplets into printing and non-printing paths. Additionally, the apparatus includes a means for improving drop placement on the receiver media by making small adjustments to the volumes of the printing droplets.

    摘要: An ink jet recording head having improved printing performance and improved manufacturing efficiency, a manufacturing method of the ink jet recording head, and an ink jet recording device. A head chip in which nozzles for jetting ink droplets are formed is fitted in an opening of an ink manifold via rubber sealing members, and the chip is exposed to the interior of ink supply chambers. Thus, the chip is efficiently cooled by the ink, and the temperature of the ink can be controlled so as to be within a predetermined range. Accordingly, no heat sink is necessary, and as a result, the head is easily manufactured and made compact. Since the chip is fitted in the manifold opening via the sealing members, application of an adhesive and curing time are unnecessary. Thus, manufacturing efficiency is improved.
