摘要： In an ink jet print head formed with ejection nozzles, which may use a wiping member to wipe ink adhered to the surface of the ink jet print head, it is desired to be able to perform a wiping operation in any environment without requiring a large amount of space to accommodate the liquid used during the wiping operation. To this end, a cooling unit is used which can produce water by cooling the atmosphere. This cooling unit is operated to produce water, which is brought into contact with and transferred onto the wiping member before the wiping member performs wiping.
