PROBLEM TO BE SOLVED: To provide a liquid consumption device accurately determining an effect of disturbance light by using a detection signal of an optical sensor in a state that a holder and the optical sensor have the same positional relation therebetween as that of residual state determination of liquid, and further to provide a control method of the liquid consumption device or the like. ! SOLUTION: A liquid consumption device includes: an optical sensor 80 having a light emission section 82 and a light reception section 84; a holder 21 capable of holding a liquid storage container disposed with a prism 320 having a surface facing the optical sensor 80; a movement section relatively moving the holder 21 and the optical sensor 80; and a control section 100. The control section 100 can determine a residual state of liquid in the liquid storage container on the basis of a detection signal from the optical sensor 80 in a range of a first positional relation and measures noise light on the basis of a dete |
