摘要： An increase in variation in resistance value resulting from a reduction in thickness of heaters is dealt with without increasing the manufacture costs of the print head, by allowing smaller ink droplets to be efficiently ejected. A setting for a pulse voltage is essentially varied depending on the ejection threshold energy of the head is employed so that optimum drive power conditions can be reasonably set over a range of varying resistance values resulting from differences among manufactured print heads. This provides a print head and a printing apparatus which can deal with an increase in differences among manufactured heads by allowing smaller ink droplets to be efficiently ejected without reducing the yield of manufactured print heads.

摘要： In an liquid ejection head according to the present invention having a plurality of ejection openings arranged in a predetermined direction and a plurality of electro-thermal transducers for ejecting liquid from the ejection openings and being in relative motion with a printing medium, a kinetic energy of the liquid ejected from each ejection opening constituting an end group disposed in the respective opposite end section along the predetermined direction is larger than a kinetic energy of the liquid ejected from each ejection opening constituting a central group disposed in a central section along the predetermined direction. According to the present invention, it is possible to prevent an ink droplet ejected from the ejection opening in the end group from being deviated toward the central section along the predetermined direction, whereby the generation of white streaks is avoidable when a solid printing is carried out.

摘要： An ink-jet printing apparatus and suction recovery control method which can minimize reduction in throughput while maintaining a printhead in the most appropriate condition, and can reduce the amount of wasted ink. According to the suction recovery control method, a printing period of predetermined printing operation is timed, and the number of print dots formed by discharging ink from a printhead during the predetermined printing operation is counted. Based on the timed printing period and counted number of print dots, the number of print dots per unit time is calculated. Then based on the calculated number of print dots per unit time, timing of suction recovery operation is determined, and suction recovery operation of the printhead is performed according to the determined timing.
