  • Patent number: 7654640
    Abstract: A printhead for an inkjet printer, that has a printhead IC with an array of nozzles for ejecting ink and a support structure for mounting the printhead IC in the printer adjacent a paper path. The printhead IC is mounted on a face of the support structure that, in use, faces the paper path. A flexible printed circuit board (flex PCB) has drive circuitry for operating the array of nozzles on the printhead IC. The drive circuitry has circuit components connected by traces in the flex PCB, and contacts for receiving print data from the print engine controller. The flex PCB being mounted to the support structure at the contacts onto a face that does not face the paper path such that the flex PCB extends through a bent section between the printhead IC and the contacts. The printhead IC and the circuit components are adjacent each other and separated from the contacts by the bent section of the flex PCB.

  • Publication number: 20100013888
    Abstract: A method of maintaining a printhead comprises the steps of: (i) providing a maintenance roller having a contact surface for sealing engagement with the printhead; (ii) moving the roller into a first position in which the contact surface is sealingly engaged with the printhead; (iii) moving the roller into a second position in which the contact surface is disengaged from said printhead; and (iv) rotating the roller such that the contact surface is conveyed away from the printhead. The maintenance roller does not rotate when the contact surface is sealingly engaged with the printhead.

  • Publication number: 20090289988
    Abstract: A method of cleaning an inkjet printhead, by generating a liquid foam on the ink ejection face such that particulate contaminants on the ejection surface disperse into the foam, then transferring the foam, together with the particulate contaminants dispersed within, onto a rotatable transfer surface moving relative said ejection face and, rotating the rotatable transfer surface into contact with a removal surface to remove the foam and the particulate contaminants dispersed within. Ink consumption is minimized by use of a foam and damage to the face is avoided since the rotatable transfer surface does not contact the face.

  • Publication number: 20090278885
    Abstract: A printhead maintenance station for maintaining a printhead in an operable condition. The maintenance station comprises an elastically deformable pad having a contact surface for sealing contact with nozzles in an ink ejection face of the printhead. The contact surface has a sloping profile. The maintenance station has a motor and cam arrangement for moving the pad substantially perpendicularly with respect to the ink ejection face. The pad moves from a first position in which the contact surface is sealingly contacted with the nozzles to a second position in which the contact surface is disengaged from the face. The movement and the sloping profile of the pad causes the contact surface to be peeled away from the face during disengagement.

  • Publication number: 20090231401
    Abstract: An inkjet printer with a printhead and a conduit connected to the printhead. The conduit defines a flow path for the printing fluid and has an internal cross section configured such that the surface tension of printing fluid within it favors gas bubble growth along the conduit length over radial bubble growth that would fully occlude the flow path.

  • Patent number: 7581812
    Abstract: A method of removing particulates from an ink ejection face of a printhead is provided. The method comprises the steps of: (a) providing a liquid foam on the face, thereby dispersing the particulates in the foam; and (b) transferring the foam, including the particulates, onto a transfer surface moving past the face. Ink consumption is minimized by use of a foam and damage to the face is avoided since the transfer surface typically does not contact the face.

  • Publication number: 20090216152
    Abstract: A biopsy device includes a body portion, a tip, at least one blade, and a cutter. The cannula defines at least one lumen. The cannula has a transverse aperture configured to receive tissue. The tip is located at the distal end of the cannula, and may include at least two concave surfaces. The blade extends longitudinally from the tip. A second blade may also extend longitudinally from the tip. Blades may be axially staggered relative to the cannula. Blades may also have lengths that differ from one another. In addition, a blade may have a pointed distal end, or may have a curved distal edge. The configuration of the blade and tip may provide reduced force to penetrate tissue. The blade and tip may produce a cut length that is greater than or equal to the length of the outer perimeter of the cannula.
