Abstract
Provided herein is a printing apparatus that includes a printhead assembly and a plurality of printhead pressure load modules that are adjustable on a shaft of a printhead pressure load assembly and engaged with a printhead member. The printhead pressure load module has a hollow housing, a plunger member, and a rotary cam. The plunger member and the rotary cam are movably engaged in the hollow housing. The rotary cam includes a plurality of channel members defined at an outer surface. Each channel member has a depth that is different from a depth of an adjacent channel member. A movement of the plunger member inwardly through the hollow housing defines a position of the rotary cam along the longitudinal axis with respect to the hollow housing. Position change of the rotary cam defines a force that acts on a pressure contact member and adjusts a load on the printhead assembly.
