摘要:
The ink jet recording apparatus includes: first ink tanks that are replaceable and contain first inks containing colorants; a second ink tank that is replaceable and contains a second ink containing no colorant; third ink generating means to generate third inks by mixing the first inks and the second ink; and third ink tanks that contain the generated third inks with different mixing ratios and can supply the third inks to recording heads for selective ejection.

An ink jet apparatus includes an ink jet head having in energy generator which car, generate energy employed for discharging ink as a droplet from a discharge port, and a control unit for controlling the energy generated from the energy generator so as to remove ink droplets, which adhere to a discharge port surface, by spreading the meniscus of the ink projecting from the discharge port on the discharge port surface. The apparatus is therefore capable of removing floating ink mist particles which adhere to the ink jet head.

摘要:
An in ink jet printing method and apparatus are disclosed which prevents mixing of ink with a liquid insolubilizing and/or agglomerating the ink and which can print images having excellent water resistance and high quality. Prevention of mixing of the ink with the liquid is achieved by separately arranging an ink receiver for receiving ink ejected by preliminary ejection and the liquid insolubilizing and/or agglomerating the ink ejected by preliminary ejection, or by setting the distance between the ink jet cartridge for the liquid and the cartridge for ink adjacent thereto is made larger than the distance between two adjacent ink jet cartridges. Alternatively, the direction of ejecting ports of an ink jet ejectors may be deviated. Prevention of mixing may also be achieved by using in addition to printing head ejecting ink onto a printing material, a printability improving liquid ejecting head ejecting a printability improving liquid which insolubilizes and/or agglomerates the coloring material in the ink, and recovering units for recovering the heads. Also, mixing of the ink with the liquid is prevented upon capping, wiping, suction recovering.

摘要:
This invention relates to an ink jet recording apparatus with a support member for supporting an ink jet recording head for effecting recording by ink discharge onto a recording material, comprising: recording material transport means for transporting the recording material from a feeding position through a recording position to a discharge position; and recovery means for maintaining and restoring the ink discharge state of said ink jet recording head. The driving source for driving the recording material transport means or support member is also used for driving the recovery means, and, when the power supply to the apparatus is turned on, the initial operations of at least the recording material transport means and the recovery means are conducted utilizing a single sensor.

An ink jet head cartridge includes a recording head for ejecting ink; an ink container for containing the ink to be supplied to the recording head; an ink supply port for supplying the ink from the container to the head; a porous ink absorbing material disposed in the container and having a ring shape with a central opening; and an engaging portion engaging with the central opening wherein the absorbing material has a higher density proximate to the supply port than proximate to the engaging portion.
摘要:
An ink jet recording device includes a recording head unit having discharge ports for discharging ink, ink channels communicating to the discharge ports and leading the ink thereto, and an ink tank unit for storing ink to be supplied to the recording head unit. The recording head unit consists of a device for storing parameter information concerning the ink discharge characteristics, and a protective member disposed on a side face area adjacent to the discharge port formation face for preventing the ink from flowing around.
