摘要： An ink jet printing head is attachable to/detachable from an ink jet printing apparatus and includes an electric wiring member formed of a TAB tape to which terminals are provided, and has a wiring exposed through an end section of the electric wiring member, the terminals accepting signals by making contact with a connection portion on the part of the apparatus when the head is attached to the apparatus. An opening is provided in a supporting member which supports the electric wiring member, the opening extending in a direction traversing an area where the electric wiring member is supported. Thereby, movement of liquid, such as water and ink, to the end section is blocked, the liquid moving through a gap between a back surface of the electric wiring member and a surface of the supporting member.

摘要： A printing apparatus includes a unit which counts the number of drive pulses applied to a print head and accumulatively stores the number of the drive pulses from the start of initial use of the printing head, and a unit which measures a temperature of the printing head and a time elapsed at the temperature in conjunction with each other, and stores a temperature history. The printing apparatus controls a timing of ink ejection from the printing head and an amount of ink to be ejected by adjusting a width of the drive pulses dependently on stored contents (a use history of the printing head) to maintain a stable image quality by adequately preventing ejecting characteristics and dot forming locations on a printing medium from being varied due to a use history of the print head.
