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.

Claim (Index 19):
The method of  claim 15 , wherein the maintenance cap comprises:\n a housing defining at least one chamber for receiving a liquid, the housing comprising:\n at least one opening providing 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; and \n a seal disposed around the at least one opening for engagement with the printhead; and \n at least one transducer coupled to the housing for generating ultrasound acoustic waves in the liquid contained in the chamber and printhead, thereby cleaning the printhead as a result of forces produced by cavitation of the liquid, and wherein the at least one transducer is configured to generate acoustic waves having frequencies between 20 kHz and 100 kHz.
