摘要： An inkjet recording apparatus includes a recording head, a carriage, a wiping unit, and a controller. The recording head has a discharge port face with a plurality of discharge ports to discharge ink. The carriage has the recording head mounted thereon and performs reciprocal scanning. The wiping unit includes a sheet-shaped wiping member to wipe the discharge port face and a conveying unit to convey the wiping member. The controller controls an amount of conveyance of the wiping member by the conveying unit. The controller performs control so that the conveyance amount in a first case, where a time elapsed since a last conveyance operation of the wiping member is greater than or equal to a certain time, becomes greater than the conveyance amount in a second case, where the time elapsed since the last conveyance operation of the wiping member is less than the certain time.

摘要： An ink jet recording apparatus includes a recording head ejecting ink; a buffer tank temporarily storing the ink; a mounting unit to which a main tank that stores the ink is capable of being mounted, the main tank having a first supply port from which the ink is supplied to the recording head and a second supply port from which the ink is supplied to the buffer tank; a first detecting unit detecting an ink volume in the main tank; and a control unit performing a discharge operation to discharge the ink in the buffer tank from the recording head via the main tank in a pre-transportation process in the ink jet recording apparatus. The control unit prompts a user to replace the main tank without performing the discharge operation if the ink volume detected by the first detecting unit is smaller than a threshold value.
