Ink jet recording apparatus and method of wiping recording head discharge port row groups

摘要

An ink jet recording apparatus includes a recording head, a carriage, a wiping unit, and a control unit. The recording head includes a discharging port surface provided with a first discharging port row group having at least one discharge port row formed by arraying a plurality of discharging ports in a predetermined direction and a second discharging port row group having at least one discharge port row formed by arraying a plurality of discharging ports in a predetermined direction. The carriage causes the recording head to scan reciprocally in a direction intersecting the predetermined direction. The wiping unit includes a sheet member for wiping the discharge port surface and a winding device to wind the sheet member. The control unit controls the winding device so that the first discharge port row group and the second discharge port row group are wiped with different areas of the sheet member.
