    摘要: In an ink jet head using a thermal energy for ejecting ink, this invention aims to reliably and uniformly remove kogations deposited on a heat application portion in contact with the ink. To realize this objective, the upper protective layer is arranged in an area including the heat application portion so that it can be electrically connected to serve as an electrode which causes an electrochemical reaction with the ink. The upper protective layer is formed of a material containing a metal which is dissolved by the electrochemical reaction and which does not form, on heating, an oxide film which hinders the dissolution. With this arrangement, a reliable electrochemical reaction can be produced to dissolve a surface layer of the upper protective layer, thereby removing kogations on the heat application portion reliably and uniformly.

    摘要: A recording head includes outlets disposed in a staggered pattern so that the distances from an ink inlet to the outlets differ alternately for adjacent outlets. The recording head includes an outlet group including a plurality of the outlets on at least one side of the ink inlet. The outlet group includes first outlets and second outlets, wherein the distance from the ink inlet to the first outlets differs from the distance from the ink inlet to the second outlets. First recording elements and second recording elements including heat resistors are provided. The first recording elements and second recording elements correspond to the first outlets and the second outlets, respectively, and are disposed in first ink channels and second ink channels, respectively. The first recording elements are rectangular, whereas the second recording elements are substantially square.

    摘要: This invention relates to an element substrate capable of confirming an electrical connection status before a printhead malfunctions. The element substrate is a substrate for a printhead, which is detachable from a printing apparatus and includes a plurality of printing elements, a logical circuit for controlling the printing elements, and a voltage application terminal for applying a driving voltage to drive the printing elements. The logical circuit is driven at a voltage lower than the driving voltage. The element substrate includes a connection status output circuit which outputs a signal reflecting the electrical connection status between the printhead and the printing apparatus on the basis of the driving voltage.

    摘要: Provided is a configuration for connecting common wires (a common power supply wire for connecting a plurality of printing elements commonly to a power supply and a common ground wire for connecting the plurality of printing elements commonly to a ground) to the outside, which configuration does not obstruct a constitution for reducing resistances of the common wires. For this purpose, the common wires are directly connected respectively to electrode leads of an electric wiring tape for external connection without use of electrode pads. In the case of this configuration, the widths of the common wires need not be narrower in vicinities of the electrode pads which would otherwise be in an edge of the board, and accordingly reduction of resistances of the common wires is not obstructed.
