  • Non-impact printer
    Patent number: 4775870
    Abstract: A non-impact printer has a movable printhead carriage for traversing a print medium and has a bracket, also serving as a heat sink, pivotally connected to the printhead carriage. A non-impact printhead is secured to the bracket and positioned to contact the print medium. A spring is positioned between the bracket and the printhead carriage to move the bracket and consequently the attached printhead into contact with the print medium. A printhead adjusting eccentric, causing relative motion between the printhead carriage and the bracket, enables vertical positioning of the printhead with respect to the print medium.
