<p>In inkjet printers, it becomes possible to precisely estimate a remaining ink level in detailed scales with a low-cost and simple structure using a sensor. Specifically, a relatively inexpensive sensor that can examine whether the remaining ink level is below a predetermined value or not is employed in combination with a counter (C2) that retains information about ink consumption in printing and other operations. When the sensor has detected an ink level beyond the predetermined value or the presence of ink (S301), and the counter (C2) exceeds the threshold value (T2) corresponding to the ink-out level (N) (S308), the remaining ink level is increased to correct the counter error (S310). <IMAGE></p> |
