Abstract
Disclosed are a recording head cap to be mounted on a liquid-discharging recording head so as to protect an orifice-disposed face of the recording head, and a method and device for mounting the cap on the recording head. The recording head cap has a solid elastic member for pressing the orifice-disposed face when the cap is mounted on the recording head. The solid elastic member has an ultralow sponge hardness, and allows the orifice-disposed face of the recording head to be pressed with a substantially constant and uniform pressing force without being deformed, and to be thereby reliably protected during prolonged storage without causing ink leakage.
