Abstract
An embodiment of the present invention provides a wiping method capable of preventing a problem such as color mixing or a discharge failure in a wiping operation during the reciprocating motion of a carriage. According to the embodiment, one or a plurality of orifice arrays out of a plurality of orifice arrays included in a printhead are wiped by making a sheet-like wiping member contact to the orifice surface of the printhead. After that, the wiping member is separated from the orifice surface of the printhead, and the used wiping member is wound. Then, the wiping member is made to contact to the orifice surface of the printhead again, and the next one or more orifice arrays are wiped.
