Abstract: An ink jet printing apparatus for performing maintenance ejection onto a printed image makes it possible to obtain a favorable printing image by rendering maintenance ejection ink dots inconspicuous. Pixel position comparison is performed between an objective pixel and data in a pixel position at the same address to detect whether image data is present at the same address. When the image data is not present in the same position, comparison operation is performed on a subsequent objective pixel. When the image data is present in the same position, processing with an image processing mask is performed on the image data in a print buffer. The image data in the print buffer is combined with the maintenance ejection data to generate image printing data. This image processing makes it possible to thin out dots from the image data and to render the maintenance ejection ink dots inconspicuous.

Abstract: An ink jet recording apparatus can effectively extend its lifetime with regard to disconnection without acceleration of deterioration of the heater element with aging, and can avoid adverse effects owing to its use environment, the deteriorated state of the heater element, scattering in recording heads at manufacturing, and the like. Because deterioration of recorded images caused by disconnection in heaters can be avoided, stable image quality can be obtained. The ink jet recording apparatus has a plurality of heater elements in a recording head thereof, for ejecting ink by heating of the heater elements, and includes a control unit for executing driving control of the heater elements. The same heater element is driven for recording under different driving conditions, independently of recording data.

Abstract: A liquid discharge head cartridge includes a recording element unit having a plate member with liquid supply paths for supplying liquid to a recording element base plate for recording by discharging the liquid; a liquid supply unit portion having a communication passage for conducting liquid from a liquid supply source; and an elastic sealing member that forms a seal between one end portion of the liquid supply paths of the plate member and an end portion of the communication passage facing the one end portion of the liquid supply paths. The elastic sealing member is provided with liquid flow paths communicating with the liquid supply paths and the communication passage. The liquid supply unit portion and the recording element unit are adhesively bonded with each other at locations other than those having the elastic sealing member arranged thereon.

Abstract: 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.

Abstract: Disadvantages relating to ink refill specific to an increase in a number of ink ejection openings in an ink jet print head is eliminated to provide a particularly excellent fast-response capability and ejection performance. More specifically, when an ink is supplied to a liquid chamber via an ink supply path and an ink supply opening formed in a support member and a print element substrate in a print head, and is then ejected from ejection openings, a pressure of an ink effected upon the ejection is transmitted to the ink supply path. This pressure, however, can be absorbed by air chambers via communication paths to reduce adverse effects of the pressure on ink refill in the liquid path after the ejection. In this case, since the air chambers and other components are structured to be closed with respect to the atmosphere, problems such as an increase in viscosity which are associated with communication of the air chambers and other components with the atmosphere can be prevented.

Abstract: In the electrode pads in the ink jet print head substrate that uses ball bumps, bonding of the ball bumps is carried out in satisfactory condition despite reduced thickness of films in the substrate. In an ink jet print head substrate, which has a heater film constituting the heater portions, a second electric wire in electrical contact with the heater film to supply it with electric power, and a first electric wire constituting a common electrode of a matrix wire for selectively driving the heater portions, the first electric wire is used as the electrode pads to which the ball bump is joined. The first electric wire does not need to be reduced in thickness even when the thickness of the protective film is reduced. Thus, an ultrasonic wave can be transferred well to the electrode pad during ultrasonic bonding.
