ABSTRACT:
An object of the invention is to provide a less costly print head maintenance mechanism featuring a compact, simple construction and negating the need for a widthwise increase of space for permitting vertical movement of the print head maintenance mechanism. The mechanism is designed to utilize the rotation of first cams and second cams for switching cap holders and wiper holders to a printing mode position for permitting a normal printing operation, a capping mode position for sealing a nozzle surface at a print head with the cap, and a wiping mode position for cleaning by wiping the nozzle surface with the wiper.
