A system for dissipating electrostatic charge build-up in printers comprises a ribbon frame made of statically dissipative material and adapted to support a printhead bracket on which a thermal printhead is mounted proximate to a rotating platen. The statically dissipative ribbon frame may be grounded to the printer power supply which in turn is grounded to the main printed circuit board assembly (PCBA) of the printer which is connected to earth ground. The electrostatically dissipative material in the ribbon frame automatically dissipates static electric charge as the moving ribbon comes into physical contact with at least one portion of the grounded ribbon frame during printer operation. The printhead bracket may also be made of statically dissipative material and grounded to the PCBA. The electrostatically dissipative material in the printhead bracket automatically dissipates static electric charge as the moving ribbon comes into physical contact with at least one portion of the grounded printhead bracket.
A system for dissipating static electric charge build-up caused substantially by the passage of a moving ribbon between a platen and a thermal printhead, said system comprising:
A system for dissipating static electric charge build-up from an ink carrier ribbon moving between a platen and a printhead, said system comprising:
