Abstract
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.
