  • PRINTER WITH PRINTHEAD ASSEMBLY, CLUTCH ASSEMBLY, AND PRINTER RIBBON TRANSPORT ASSEMBLY
    Publication number: 20160059596
    Abstract: A printer may include a printhead assembly, a clutch assembly, and/or a printer ribbon transport assembly. An example clutch assembly includes a first spool engagement member defining a first friction torque; a first friction member configured to frictionally engage the first spool engagement member; a second spool engagement member defining a second friction torque that is larger than the first fiction torque; and a second friction member configured to frictionally engage the second spool engagement member.

  • Printer with printhead assembly, clutch assembly, and printer ribbon transport assembly
    Patent number: 9211705
    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.
