  • Method and apparatus for adjusting printhead to print-media travel path spacing in a printer
    Patent number: 6616354
    Abstract: Apparatus for adjusting the spacing in a printer between a printhead and the travel path for print media which moves through the printer. The printhead is borne by a carriage which is rotatably mounted adjacent an elongate bearing rail wherein the rotated condition of the carriage relative to that rail establishes the desired spacing. First and second relative moveable bearing structures mounted on the carriage include bearing surfaces which can alternatively adjust the bearing structures so that one or the other, but not both, determine the rotated condition of the carriage.
