PURPOSE:To minimize a substance to be discarded in an ink refilling method by measuring the residual amt. of ink and the components of residual ink and performing refilling corresponding to the data in the measuring process. CONSTITUTION:The measurement of an ink residual amt. and that of the components of residual ink are performed and, corresponding to the data of these two processes, the refilling of ink is performed. By this constitution, when an ink is refilled, the waste soln. discharged at the time of washing is not discharged in order to refill an ink jet cartridge with ink without containing a washing process and residual ink can be reutilized by inspection. Concretely, the ink tank is recovered and a small amt. of ink for inspection is extracted from the ink tank after the appearance inspection of the ink tank is completed to measure the residual amt. of ink. Next, absorbancy is measured and the refilling with ink is performed on the basis of the measured result to regenerate the ink tank. |
