摘要： According to the present invention, there is provided an ink jet recording apparatus for recording an image on a recording medium by discharging ink to the surface of the recording medium, wherein ink is reserved in an ink tank including a negative pressure generating member, such as an absorber and a foaming member, and a function of accurately detecting the residual quantity such that depletion to a predetermined level can be detected is realized. Light emitted by a photointerrupter is allowed to pass through a portion of a wall surface of the ink tank made of transparent plastic or the like which is transmissible with respect to detection light emitted by the photointerrupter to detect change in the light reflectance in the boundary portion between the wall surface and the ink absorber. In accordance with reflectance obtained in a case where no ink exists in the detected portion and that obtained in a case where ink exists, the residual quantity of ink can be detected.

摘要： An ink jet recording apparatus includes a cap to cover the discharge ports for discharging ink. This cap includes an atmospheric conduction passage for conductively connecting the interior of the cap with the air outside, and an ink exhausting device for exhausting ink deposited in the interior of the cap to the outside preferably by utilizing the ink's own weight. With this cap structure, ink is exhausted outside the cap, thus reliably coping with ink leakage that might otherwise take place when ink tanks are replaced or the main body is vibrated. At the same time, it is made possible to maintain the atmospheric conduction passage in good condition at all times.

摘要： This ink jet recording apparatus makes it possible to reduce the requisite number of times that preliminary ejection is performed for the purpose of ejection recovery through suction, which must be effected to such a degree as to make color mixing on the recording paper sufficiently inconspicuous. With a plurality of recording heads using inks of different lightnesses, ejection recovery is performed successively on the recording heads in accordance with the descending order of ink lightness. In addition, the number of preliminary ejections after ejection recovery to be performed on the next recording head is also controlled, thereby attaining a still greater effect. In a method aspect, the present invention includes an initial discharge step for discharging ink from a recording head, interrupting the discharge of ink for an appropriate period set in accordance with the ink lightness, and discharging ink again from the discharge ports of the recording head after the interruption.
