Printer having relative arcuately moveable simplex printhead and capping and purging mechanism

摘要

A printer having a pagewidth printhead assembly and a capping mechanism. The printhead assembly has a single pagewidth printhead and ink ejection nozzles located along the printhead for delivering ink onto print media as it is transported past the printhead. The capping mechanism has a capping member having a length corresponding substantially to that of the printhead and located in a non-capping first position spaced-apart from the printhead, a first actuating mechanism arranged to move the printhead in an arcuate first direction from a first position to a second position and a third position, and a second actuating mechanism arranged to move the capping member in an arcuate second direction opposite to that of the first direction to effect nozzle capping engagement of the printhead when the printhead is in the second position and to permit purging of the nozzles when the printhead is in the third position.
