Abstract
A valve is disclosed for use in a maintenance station for an ink jet printer. The maintenance station has a carriage on which a cap that selectively seals the printhead nozzle is mounted. The carriage is movable in and relative to a fixed support member of the maintenance station. A flexible hose interconnects the cap with a pneumatic source for the removal of air and ink from the cap. The selective movement of the carriage towards and away from a wall of the support member pinches the flexible hose closed between them without requiring closely toleranced movement of the carriage.
