摘要： An ink jet apparatus, used with an exchangeable ink jet cartridge having an ink jet head and an ink container, includes a cap, a sucking device and a controller. When the cap caps the ejection orifices of the recording head, the sucking device sucks ink from the ejection orifices. The controller controls the operation of the cap and sucking device. After a sucking operation is performed, the cap is held away from the ejection orifices for a predetermined duration of time; the capping and sucking operations are then repeated.

摘要： A recording apparatus which is provided with a plurality of heads accompanied with temperature rise in recording by the application of driving signals comprises means for detecting the temperature in apparatus to detect temperatures in the recording apparatus; means for obtaining the temperature of the recording head from an offset value set between the temperature in apparatus and the temperature of the recording head of the recording apparatus in accordance with the detection by the aforesaid means for detecting the temperature in apparatus; and means for controlling the driving signal to change the waveforms of the driving signal applied to the recording head. With the structure arranged as above, the offset temperature is varied in accordance with the operational situations to obtain the head temperature without detecting it directly, hence maintaining the discharging amount constantly in printing and between environments in order to suppress the variation of the density of images to be printed, and also, reduce the cost of the printer main body and that of the head significantly.

摘要： By using an ink jet head, which has for each color two parallel columns of nozzles arranged side by side in the main scan direction and shifted from each other by one-half the pitch at which the nozzles are arranged in each column, odd-numbered rasters and even-numbered rasters making up an image are printed by the two nozzle columns. The registration between the odd- and even-numbered rasters is secured during the printing to produce an image with high print quality. For that purpose, the ink ejection timing between the two raster groups is shifted by a predetermined interval to form a plurality of adjustment patterns; the adjustment patterns printed are checked and, according to the check result, an adjustment value for the ink ejection timing between the two ink nozzle columns is entered, and the entered adjustment value is stored to be reflected on the actual printing operation. To facilitate the adjustment pattern check, the plurality of adjustment patterns have a dot distribution with a blue noise characteristic at a resolution at which the printing apparatus can print.

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 capable of forming a high quality multivalued image without using a plurality of print heads and suited for a size reduction is provided. In an ink jet printing apparatus in which the electrothermal transducers are heated by a drive pulse to generate bubbles in ink and in which the pressure of the bubbles is used to eject ink droplets from nozzles onto a print medium to print an image, the drive voltage and the drive pulse width for the print head are changed simultaneously in accordance with print data. For example, when ejecting small droplets, the drive voltage for the nozzles is increased and the drive pulse width shortened. When ejecting large droplets, the drive voltage is lowered and the drive pulse width elongated.
