  • Publication number: 20150151538
    Abstract: A printer may include a printhead assembly a clutch assembly, and/or a printer ribbon transport assembly. The printhead assembly may include a printhead biasing assembly defining a biasing ramp which may be configured to apply a biasing force to a printhead support bracket so as to at least partially counteract a ribbon force. The clutch assembly may be configured to supply or take-up a printer ribbon with first and second spool engagement members of different diameters that frictionally engage first and second friction members. The printer ribbon transport assembly may include a rotation lock mechanism configured to prevent rotation of a ribbon take-up core when the take-up core is disengaged from a drive assembly so as to prevent a loss in ribbon tension.

  • Publication number: 20120119011
    Abstract: Embodiments of the present invention are related to a media transport assembly for printers, such as a kiosk printer. The media transport assembly may comprise a biased guide roller structured to dampen media tension shocks, discontinuities, or variations. Other embodiments of the present invention may also provide a media transport assembly configured to allow increased flexibility in media supply roll mounting and for easy loading and threading of the media.

  • Patent number: 6929346
    Abstract: A system for servicing a non-scanning printhead includes a servicing plate, a servicing component mounted on the servicing plate and adapted to service the non-scanning printhead, and a drive system adapted to move the servicing plate between a storage position and a service position such that the servicing component is spaced from the non-scanning printhead when the servicing plate is in the storage position and the servicing component is adapted to service the non-scanning printhead when the servicing plate is in the service position.
