ABSTRACT:
An integral seal for priming or maintaining the nozzles or orifices of an ink jet printhead in an ink jet printer. The ink jet printhead includes a plurality of ink ejecting orifices arranged on a surface of the printhead and includes a seal integral with the surface which surrounds the ink ejecting orifices. The seal member is located within a recess formed in the surface and has a contacting surface which can be recessed from the ink ejecting orifices so that cleaning operations of the surface which, for instance, use a wiping blade, are not impeded. A capping member on a maintenance station contacts and slightly compresses the seal member to provide an airtight seal during priming/maintenance operations.
