Abstract
A cap is provided with a contact section for contacting and enclosing the periphery of a nozzle array of a print head when the print head is in a capped state, and a deforming diaphragm having a deformable bag-shaped section in a position enclosed by the contact section. In the case of a temperature change in an enclosed space between the contact section and the nozzle, the bag-shaped section expands or contracts to keep a constant pressure, thereby protecting a print head meniscus from breakage and accordingly preventing the occurrence of defective printing. Furthermore, the capping device is separate from a recording device, so that it can be attached to a head unit removed from a printer at the time of shipping the head unit from a factory, to thereby prevent the nozzle array from drying out.
