  • Patent number: 9573380
    Abstract: A printer which is configured so that an ink tank which accommodates ink is fixed and a user can refill the ink tank with the ink, includes one pair of electrodes which are disposed in the ink tank and serve as sensors for detecting whether or not the ink is present at a predetermined height (first threshold value). A control portion which controls the printer performs liquid presence detection to detect whether or not the ink is present at the predetermined height (first threshold value) by using the sensors, and performs initial filling which corresponds to the result of the detection.

  • Publication number: 20160279963
    Abstract: A printer to which an ink tank that contains an ink is fixed and that is configured such that a user can refill the ink tank with the ink includes: a consumption amount calculation unit that calculates a consumption amount of the ink; a storage unit that stores a count value that is updated based on the consumption amount of the ink calculated by the consumption amount calculation unit; a sensor that detect whether or not the ink is present at a predetermined position in the ink tank; and a control unit that executes ink presence/absence detection with the sensor. The ink presence/absence detection is for determining whether or not the ink is present. The control unit resets the count value to an initial value thereof if the control unit executes the ink presence/absence detection and determines that the ink is present.

  • Patent number: 8840716
    Abstract: It is an object of the present invention to provide an ink set which makes it possible to obtain recorded images that have a broad color reproduction range and a high saturation, as well as glossiness without conspicuous graininess caused by dot expression, and which in particular makes it possible to achieve an extreme suppression of graininess caused by dot expression in cases where the ink set is used on media that have a coating layer, and to obtain recorded images with extremely superior coloring characteristics in cases where the ink set is used on ordinary paper. The present invention provides an ink set comprising at least a yellow ink (Y), magenta ink (M), cyan ink (C) and red ink (R), wherein the L* values in the CIE-stipulated Lab display system of aqueous solutions of the respective inks diluted 1000 times by weight are in the following ranges: (Y): at least 89 but no more than 94, (M): at least 76 but no more than 93, (C): at least 74 and no more than 87, (R): at least 55 and no more than 74.
