Abstract
Provided is a printhead maintenance station for a pagewidth printer. The maintenance station includes a capper having an open-ended capping chamber with a perimeter gasket for operatively engaging with a printhead of the printer to form a protective seal around the printhead. Also included is an engagement mechanism configured to actuate said capper into and out of sealing engagement with the printhead, as well as an air supply and vacuum assembly with valve arrangements arranged in fluid communication with the capping chamber to facilitate in purging excess ink from the printhead when the capper is engaged with said printhead.
