  • Patent number: 8668318
    Abstract: A leveling and spreading system has been developed that enables the speed and position of the web to be determined from a sensor on a first roller. In a duplex print process, the first roller also reduces a temperature of the media web and an ink image printed in the first side print operation to within a first predetermined temperature range. A second roller modulates the temperature of the media web and ink ejected onto the media web immediately before the web enters the leveling and spreading system to within a second predetermined temperature range to enable uniformity of the ink and web temperatures for spreading the ink in a nip formed with a third roller.

  • Publication number: 20130300800
    Abstract: A printhead wiper assembly includes an elongated member having a first and second wiper, a linkage, and an actuator. The linkage includes a clutch that enables the elongated member to move to a plurality of positions in response to the actuator activating a plurality of times. The sequence of positions enables first wiper and then the other wiper to contact the printhead face to remove purged ink from the face.

  • Publication number: 20130300794
    Abstract: An inkjet printer for printing on a continuous web of recording media includes a receiver to receive a beam of collimated light transmitted across the surface of a continuous web of recording media supported by a roller. The intensity of the transmitted beam received by the receiver can be used to determine the presence of a defect in the continuous web or in the roller. A controller is configured to reduce the speed of or stop movement of the web through the printer and to retract one or more printheads from a printing location to prevent the defect from damaging the printhead(s).

  • Patent number: 7131454
    Abstract: A system for injecting a predetermined amount of a secondary fluid into a primary fluid stream uses a liquid additive injection pump driven by a fluid powered motor driven by the primary fluid stream. The liquid additive pump has a reciprocating piston movable within a cylinder between upstroke and downstroke positions to meter the secondary fluid and a piston sealing mechanism comprising spaced-apart distal and proximal sealing elements. The distal piston-sealing element is flared in the direction of piston downstroke and the proximal piston-sealing element is flared in the direction of piston upstroke.
