    摘要: A printing apparatus and a print control method which detect a defective printing element in operation failure status while reciprocate-scanning a printhead, and perform appropriate print control such as complementary printing on an unprinted portion by the defective printing element, without reducing the printing speed. An apparatus, to which the method is applied, has a photosensor 8, to detect ink discharge statuses of a plurality of nozzles of a printhead 5, which is provided between a home position of the printhead and the outside of an effective printing area where image printing is to be made. While the printhead 5 is scanned, test ink discharge is performed at the position of the photosensor 8, and the ink discharge statuses of the nozzles are detected by the photosensor 8. A corrector 123 analyzes the operation statuses of the nozzles of the printhead 5 based on the results of detection in a real time manner. A CPU 25 performs print control based on the results of analysis.

    摘要: A fuel-effusion prevention valve includes a first housing member having an evaporation passage, a first engaging portion and a first cylindrical portion, and a second housing member having a partition portion, a communicating passage, a second engaging portion and a second cylindrical portion. The first cylindrical portion is formed so as to extend axially from the first engaging portion, and its diameter is smaller than that of the second engaging portion. The second cylindrical portion is formed so as to extend axially from the second engaging portion. A floating valve is disposed in a chamber so as to be able to open and close the valve hole in response to its buoyancy due to fuel flowing into the second chamber through the communicating passage. The first cylindrical portion is fused with the second cylindrical portion. A circular seal member is fitted into an installation hole formed on the fuel tank and its inner hole is fitted onto the outer circumferential surface of the first cylindrical portion.

    摘要: In an image recording apparatus having a recording head, recording may be interrupted (for example, to permit transfer of new image data after a predetermined amount of recording is performed). Recording quality is maintained by compensating for the change in head temperature which occurs during the interruption. This is done by detecting the temperature of the recording head and/or counting the interruption time, and driving the recording head in a stand-by mode or correcting the image signal in accordance with the temperature difference between interruption and resumption of recording.
