  • Patent number: 8657396
    Abstract: 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.

  • Patent number: 8152277
    Abstract: The printing head has connection terminals for performing an electrical connection of signals including drive signals of print elements by contacting connection terminals in on an apparatus side when the head is mounted onto an ink jet printing apparatus. Connections of all terminals can be guaranteed by detecting contacts of a part of terminals. Among the terminals in the head, terminals whose distances from the connection terminals in the printing apparatus become maximum when a deviation occurred in the mounting are used as terminals for contact detection. For example, from among the connection terminals arranged in a planar area, which is rectangular-shaped, terminals positioned in corners are used as the terminals for the contact detection. When the contacts of these terminals are detected, the connections of all the terminals inside the area can be guaranteed.
