1. A cap actuating assembly for ink dispensing nozzles of a printhead of a printing apparatus, the printhead being reciprocally moved along an axis through a printing region in response to a drive assembly and through a storage region where a cap is advanced toward the printhead in a direction generally perpendicular to the axis for sealing the nozzles, the actuating assembly comprising:

  • a pivoting member that is received on a pin mounted on the printing apparatus for rotation about the pin between first and second positions;

    an actuating arm extending from the pivoting member and disposed in a path of movement of the printhead as the printhead enters the storage region;

    a movable base on which the pivoting member is mounted for selective reciprocation in a direction generally parallel to the axis; and

    a cap mounted on the pivoting member for selected movement toward and away from the sealing relation with the nozzles in response to movement of the pivoting member between the first and second positions of the actuating arm.
