20110310159 | INKJET APPARATUS AND METHOD OF JUDGING REPLACEMENT TIMING FOR COMPONENTS OF THE APPARATUS - In an inkjet apparatus using an inkjet head ejecting multiple types of inks different in viscosity after evaporation of solvent, a replacement timing for a component is judged by using a consumption amount of each type of ink and a generation rate in amount of ink droplets. Accordingly, in the case of using a large amount of ink strongly susceptible to fixed adhesion and increase in viscosity, the component is replaced at an earlier timing, which prevents fixed adhesion from influencing the print performance and the printing apparatus main body. By contrast, in the case of using a large amount of ink less susceptible to fixed adhesion and increase in viscosity, the component is replaced at a later timing and thus can be used until reaching its lifetime. | 12-22-2011 |
20110310160 | INKJET APPARATUS AND METHOD FOR JUDGING REPLACEMENT TIMING FOR COMPONENTS OF THE APPARATUS - In an inkjet apparatus capable of ejecting an ink and a treatment liquid for insolubilizing or coagulating a color material in the ink, a replacement timing for a component of the apparatus is judged based on both the consumption amounts of the ink and treatment liquid measured when the two are consumed together and the consumption amount of the ink measured when the ink is consumed alone. Thus, the component is replaced at an earlier timing when the influence of fixed adhesion is great due to frequent ejection of both of the ink and treatment liquid, which prevents fixed adhesion from influencing the print performance and the printing apparatus main body. By contrast, when the fixed adhesion slowly develops because of less-frequent ejection of both of the ink and treatment liquid, the component is replaced at a later timing and thus can be used until reaching its lifetime. | 12-22-2011 |
