ABSTRACT:
When a printhead is not in use, it remains filled with ink. In order to prevent evaporation of the ink through the nozzles of the printhead, and the consequential depositing of ink components in and around the ink nozzles, the invention provides capping of the nozzle during the non printing modes of the printer. The capping mechanism uses a page width elastomeric seal, which can move between a first capping position, in which it seals said nozzles of the printhead in an air tight manner, and a second position in which the elastomeric seal moves away from said print head to allow paper to be printed upon by said print head.
