  • Patent number: 6641248
    Abstract: A cap device is for capping a head of an ink jet printer. The cap device includes a cap, an ink absorption member, and a lid. The cap is for developing a seal around the ink ejection surface of the head. The ink absorption member is disposed in the cap to absorb ink that was ejected or sucked from the head into the cap. The lid covers an ink-ejection-surface-confronting portion of the ink absorption member, except at least a nozzle-confronting portion of the ink absorption member. The lid is connected to an inner peripheral surface of the cap with a fluidly tight connection.
