摘要:
The present invention relates to a cartridge having a liquid discharger removably mounted onto a main body of a liquid jet recording apparatus. The cartridge comprises a humidifier for humidifying a liquid discharging portion of the liquid discharger, an input member for receiving delivery of an actuating force for actuating the humidifier, an electric contact member for receiving an electric signal actuating the liquid discharger, and a box member for containing the humidifier, input member and electric member.

An ink jet recording apparatus for performing recording by ejecting ink to a recording medium, has a recording head and head driving unit. To effect ejection recovery, the head driving unit drives selected ejection energy generating elements in the recording head so that ink is ejected from orifices which correspond to the selected ejection energy elements. The selected orifices include at least one orifice adjacent to a particular orifice at which ink ejection recovery is performed, but exclude the particular orifice in an arrangement of the plurality of orifices. This ejection recovery technique efficiently removes bubbles from the particular orifice.

A fixater has a fixing unit for expediting the fixation of an image recorded on a recording medium, a conveying unit for conveying the recording medium and a coupling unit detachably mountable in the mounting section of a cassette for stacking the recording medium for the recording apparatus. The fixater is mountable in place of the cassette for stacking the recording medium.

An ink jet head cartridge includes an ink jet head unit having an ink passage in which an energy generating element for generating energy used to discharge ink is disposed, and an ink tank adapted to store the ink to be fed to the ink passage and having a vent opening for permitting the interior of the ink tank to communicate with the atmosphere and being formed integrally with the ink jet head unit. In the ink jet cartridge an area where an ink absorber is disposed, and an air area at least a part of which is defined by a tubular member and which is filled with air, are formed in an internal space of the ink tank, and a porous member is disposed in an air passage extending from the air area to the vent opening. An ink tank can be incorporated into the above-mentioned ink jet head cartridge, and an ink jet recording apparatus utilizing the above-mentioned ink jet head cartridge can be provided.

An inkjet printing apparatus, an inkjet printing system and an inkjet printing method are provided in order to correct a print density at a joint (overlapped portion) of nozzle arrays of a print head. The print density at the joint (overlapped portion) of the nozzle arrays is corrected based on a positional deviation between two adjacent nozzle arrays of the print head.

摘要:
Disclosed herein is an ink comprising a first pigment, a second pigment and a dispersant, both of the pigment being dispersed in an aqueous medium, wherein the first pigment is a self-dispersing pigment having an anionic group or a cationic group, the group being bonded directly or through an atomic group to a surface of the pigment, the second pigment is a pigment dispersible in an aqueous medium with the dispersant, and the dispersant is an ionic polymeric dispersant having a same polarity as that of the group bonded to the surface of the pigment or a nonionic polymeric dispersant.
摘要:
A region to be covered by a cover plate on an ejection opening forming surface of an ink-jet head or an ink-jet head to which the cover plate is installed are determined, on a basis of content of a rebounding mist generated upon ejection of an ink and a processing liquid in overlaying fashion. By this, in the ink-jet printing apparatus performing printing by ejecting the ink and the processing liquid for making the ink insoluble, deposition of the insoluble substance contained in the rebounding mist generated upon ejection of an ink and a processing liquid in overlaying fashion can be successfully prevented.
摘要:
A method and an apparatus for ink jet printing use a print head including a first nozzle group for discharging a first ink, a second nozzle group for discharging a second ink and a third nozzle group for discharging a printability improving solution. The third nozzle group is displaced between the first nozzle group and the second nozzle group. The first nozzle group discharges the first ink on the printing medium based on image data to form an image, the third nozzle group discharges the printability improving solution on the image formed on the printing medium by means of another step, and the second nozzle group discharges the second ink on the image formed on the printing medium. The printability improving solution has higher penetrability into the printing medium compared to the ink.The method and apparatus can attain a clear colored, high density image without color mixing, which has high water resistance on plain paper, with a low running cost.
摘要:
A printing head having a nozzle group for ejecting an ink and a nozzle group for ejecting a printing ability improving liquid is used, and printing control is made so that the number of scannings of the printing head is increased as a print duty increases, thereby reducing generation of mist due to rebounding of the ink or the printing ability improving liquid from a printing medium side.
