No fluid communication exists between the first section of the array and the second section of the array. The printhead integrated circuit has channels for supplying ink to the array of ink ejection nozzles. Each of the channels being divided into channel sections by transverse walls. The apertures in the polymer sealing film are positioned at each of the transverse walls such that each of the apertures supplies ink to both the channel sections either side of one of the transverse walls. | 2009-12-03 |
20090295865 | HEAD MOVING MECHANISM AND IMAGE FORMING APPARATUS - A head moving mechanism includes a printhead configured to form an image and movable between a printing position where an image is formed, a standby position away from the printing position, and a retracted position across from the printing position relative to the standby position; a cam mechanism configured to move the printhead between the printing position and the standby position; and a rack-and-pinion mechanism configured to move the printhead between the standby position and the retracted position. | 2009-12-03 |
20090295866 | Printbar Support Mechanism - A web press printer includes a printbar supporting an array of printheads extending across a media web. The printbar includes a support member coupled to the printbar via one or more biasing mechanisms to locally counteract a deflection of the printbar at a location of one or more of the respective printheads along the printbar. | 2009-12-03 |
20090295867 | LIQUID EJECTING HEAD UNIT AND LIQUID EJECTING APPARATUS - A liquid ejecting head unit including a plurality of liquid ejecting heads is disclosed. A platform on which the plurality of the liquid ejecting heads are mounted in a staggered arrangement in the first direction, each liquid ejecting head being partially adjacent to each in a second direction, which is orthogonal to first direction. A common trunk passage communicates with the liquid passage ports. A plurality of branch passages communicates with the trunk passage. A plurality of branch circuit wiring sections connects to connectors of the liquid ejecting heads. The plurality of liquid ejecting heads are mounted such that liquid passage ports of each partially adjacent liquid ejecting head are not adjacent to each other in a second direction, and such that the connectors of each partially adjacent liquid ejecting head are not adjacent to each other in the second direction. | 2009-12-03 |
20090295868 | Printhead Having Ejection Nozzles Over Wide Printing Zone - A printhead is provided having an elongate carrier, a plurality of ejection nozzle integrated circuits mounted on the carrier, and control circuitry positioned on the carrier and operatively connected to the ejection nozzle integrated circuits to control operation thereof. The mounted ejection nozzle integrated circuits have more than 150,000 ejection nozzles | 2009-12-03 |
20090295869 | Nozzle Plate for an Ink Jet Print Head Comprising Stress Relieving Elements - The invention relates to an ink jet print head structure for printing devices, comprising a substrate in which one or more slots are realized and a nozzle plate connected to the substrate. The nozzle plate defines a first axis (X) and a second perpendicular axis (Y) and comprises a plurality of nozzles from which ink is ejected in fluid communication with the slots. The slots extends along the second axis (Y). A plurality of strip-like stress relief elements is realized on the nozzle plate, the plurality of stress relief elements is disposed so to extend along the Y axis, and each stress relief element of the plurality defines an aperture on a free surface of said nozzle plate. In addition, the total X projections of all apertures defined by the plurality of stress relief elements along the first (X) axis has a resulting length comprised between 10% and 55% of the overall width of the nozzle plate along the same first axis (X). | 2009-12-03 |
20090295870 | NOZZLE PLATE FOR IMPROVED POST-BONDING SYMMETRY - A nozzle plate for bonding to a chip for configuring a printhead of a printing device is disclosed. The chip comprises a plurality of energizing elements. The nozzle plate comprises a substrate layer, an adhesive layer and a plurality of nozzle holes perforated in the substrate layer and the adhesive layer. The each nozzle hole is capable of being associated with an energizing element of the plurality of energizing elements. The each nozzle hole comprises an asymmetric flow-feature configured by ablating at least a portion of a wall of the each nozzle hole prior to bonding the nozzle plate to the chip. The nozzle plate provides a substantially symmetrical flow-feature for the each nozzle hole on bonding to the chip. | 2009-12-03 |
