Abstract:
There are provided a method of detecting an ink residual quantity and a printing device which do not make an erroneous determination as to detection on presence/absence of ink without influence of ink mist generated in the middle of using a printing device on calibration of an optical sensor. Therefore, by performing allotment processing based upon ink tank memory element information, calibration of an optical sensor using a reflection portion equipped in the ink tank, in a state where it is determined that the ink is left in the ink tank.
