摘要： An inkjet printing apparatus capable of detecting an ink amount in an attachable inktank at a multi-level with a simple arrangement has the following arrangement. That is, the printing apparatus includes a printhead which prints an image by discharging ink, an inktank which contains the ink supplied to the printhead, a reservoir capable of temporarily containing the ink supplied from the inktank, and a detection unit which performs a detection operation of detecting whether the ink amount in the inktank is more than a predetermined amount. Then, the detection unit performs the detection operation in a state in which the reservoir contains the ink supplied from the inktank.

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.

摘要： A printing apparatus is operable to eject a plurality of inks having different functions onto any one of a plurality of types of printing medium. The plurality of inks include a first ink containing a coloring material, and a second ink containing a polymer emulsion and substantially no coloring material. The plurality of types of printing medium includes a first printing medium and a second printing medium less permeable to liquid than the first printing medium. When the first printing medium is printed, the first ink is used without using the second ink, and when the second printing medium is printed, both the first and the second ink are used.
