ABSTRACT:
An inkjet printhead capping mechanism includes an arm arranged to rotate about a pivot point. A capping assembly is located on one end of the arm whereas a slip wheel is located at the other with the pivot point being located between the two. The slip wheel is periodically driven by a drive wheel of the printer's print media transport mechanism so that the arm pivots to bring the capping assembly to a capping position whilst the printer is not printing. Springs act to bias the capping assembly in the capping position. The capping assembly includes a sponge, which acts as an ink blotter, and a pair of seals located on opposite sides of the sponge to make an air tight seal around the printhead.
