Controllers on the master and slave sides each perform an ink cartridge checking process and transmit a detection result, for example “NG”, obtained though the ink cartridge checking process to the other controller. Furthermore, the same ink cartridge checking process is performed in the other controller and the detection result thereof, for example “OK” is transmitted to the first controller. A mechanical control unit merges (combines) the respective detection results and if at least one of the results is NG, a merged result of NG is obtained. In the case of NG, this fact is transmitted to a host control unit and if YES is selected in a Y/N display, the error is cleared. On the other hand, in the case of a merged result of OK, an ink cartridge OK state notification is issued to a mechanical controller. |
