Abstract
A maintenance cap is provided for in-situ attachment to a printhead of printing apparatus. The maintenance cap comprises a housing defining at least one chamber for receiving a liquid. An opening in the housing provides a path for the liquid to pass from the chamber into a portion of the printhead when the maintenance cap is engaged with the printhead. The maintenance cap also includes a seal disposed around the opening for engagement with the printhead. A transducer coupled to the housing is used to generate ultrasound acoustic waves in the liquid contained in the chamber and printhead so as to clean the printhead.
