Abstract
Provided is an apparatus capable of mounting an expendable cartridge thereon, including: a consumption amount counting unit that counts up the consumption amount of expendable cartridges in the apparatus when a change is detected for the first time during the continuous operation or the apparatus. The detected change is a residual expendable amount of the expendable cartridge decreasing from a value higher than a predetermined low residual level to a value lower than or equal to the low residual level. The consumption amount of the expendable cartridges is counted up and is detected in a number of different manners, depending on the circumstances surrounding the measured values of the residual expendable amounts and the replacement of the cartridges.
