ABSTRACT:
A method of maintaining a printhead in an operable condition is provided. The method comprises the steps of: (i) providing a printhead assembly comprising a printhead having an ink ejection face and a film guide sealingly bonded to the face, the film guide being positioned to guide a film through a transfer zone defined by a plane spaced apart from the face; (ii) positioning at least part of a film in the transfer zone and in sealing contact with the film guide, thereby forming a cavity defined at least partially by the film, the film guide and the face; and (iii) feeding the film through the transfer zone and away from the printhead, thereby removing ink from the cavity.
