摘要： An inkjet printing apparatus is adapted to use a non-contact method for detecting the presence and the amount of liquid, in the form of ink droplets discharged from a printhead or ink tank, using electromagnetic waves in the form of infrared rays. The apparatus and method employ an infrared sensor to detect infrared radiation emitted by the ink in proportion to the amount of ink present. The apparatus and method further employ one of various shielding members to prevent the intrusion of infrared radiation noise into the infrared sensor field of detection, and, in some aspects, a fan to control air flow within the field of detection. The result is less noise in the detection signals of the infrared sensor, and therefore a more sensitive and more reliable liquid detection method and liquid detection apparatus.

摘要： The present invention allows the detection of ink in a printing head that can be widely applied to various printing systems by significantly simplifying its configuration. There are a heater for supplying an energy to eject ink, a driver for driving the heater, and a detection electrode capable of detecting a voltage variation that arises between the heater and the driver and that depends on the driving of the heater. Furthermore, an insulating film that covers the surface of the detection electrode protects the detection electrode from chemical or physical change. Furthermore, a reference element group or a reference unit that produces a signal as a reference of the detection signal avoids the influence of noise. Furthermore, an energy-generating element and another signal source improve the accuracy of ink detection. A drive pulse which is insufficient to eject ink may be supplied to the heater to improve the accuracy of ink detection.

摘要： A head for discharging yellow ink, magenta ink, cyan ink and first black ink having a relatively fast penetration velocity to a recording medium and a head for discharging second black ink having a relatively low penetration velocity are used to print an image. When a black image is adjacent to a color image, the black image is formed by using the first black ink, and when the black image is not adjacent to the color image, the black image is formed by using the second black ink. A black ink and a plurality of color inks having a different penetration velocity to a recording medium than that of the black ink are also used to print an image. Whether a color image area is present in the vicinity of a black image area of record data or not is determined, and whether the black image area is to be formed by the black ink or by the color inks is decided in accordance with the determination result, and when the black image is to be formed by the color inks, the color inks are used based on a mask pattern pseudo-randomly prepared to make the change in tonality less recognizable.
