<p>There is a case where, in the individual tank number checking processing, usually it is determined that individual tank number agreement can not be confirmed due to a collision of response signals from two tanks. However, due to individual differences among main body side control circuit threshold values and the like, there may be a case that an agreement of the individual tank numbers is confirmed. In response to this, the tank that has the individual tank number whose agreement could be confirmed is put in a sleep state, and because a control code is sent, the other tank designated with color ID is able to return its individual tank number, and the main body side control circuit detects its individual tank number. Based on this it is possible to determine that multiple ink tanks with the same color ID are mounted.</p> |
