Abstract
Apparatus and method for adjusting and maintaining printhead-to-platen spacing in a printing device, wherein the printing device includes a printhead-carrying carriage and the carriage is pivotally mounted on and reciprocally shiftable along a guide shaft. An anti-rotation rail mounted on a hanger in the printer engages the carriage and determines its position relative to the printer's platen. A clamp structure is connected to the anti-rotation rail and extends through the hanger and is operable for clamping the anti-rotation rail to the hanger. An adjuster mechanism connected to the clamp structure is operable for selectively shifting the anti-rotation rail vertically upwardly or downwardly to position and maintain the carriage, and correspondingly, the printhead a preselected, nominal distance from the platen.
