Abstract:
A mechanism for recovering an ink-jetting head, comprising:a cap to cover at least a nozzle hole of said ink-jetting head; a cap movement mechanism to move said cap relative to a nozzle plate on which said nozzle hole is equipped; a depressurizing device; and a controller to control said cap movement mechanism, so that said cap moves relative to said nozzle plate to a first position at which said cap air-tightly seals a region of said nozzle plate including at least said nozzle hole, and moves relative to said nozzle plate to a second position at which said cap contacts said nozzle plate to generate a gap between a lip portion of said cap and said nozzle plate, wherein said depressurizing device operates to depressurize a space covered by said cap, when said cap is positioned at said first position, and said depressurizing device operates, when said cap is positioned at said second position.
