ABSTRACT:
An apparatus for adjusting a spacing between a printhead and a print medium in a printer is provided. The printhead is mounted in a carriage which is slidable along a guiding rod. The apparatus includes a first and second assembly for adjusting a position of a first and second portion of the carriage, respectively. The second assembly includes a camshaft attached to and slidable with respect to the carriage, one or more cams attached to the camshaft, and a bushing member. A first surface of the bushing member abuts a predefined profile of the cam, and a second surface of the bushing member abuts the guiding rod. The sliding of the camshaft with respect to the carriage causes a distance between the bushing member and the camshaft to vary according to the predefined profile of the cam. Accordingly, the spacing between the printhead and the print medium is adjusted.
