INK FEED STATION IN INK-JET PRINTER, INK FEED CONTAINER USED FOR THE STATION, AND FEED METHOD FOR REPLENISHMENT INK FEED COMPONENT

摘要

PROBLEM TO BE SOLVED: To reduce a replenish time for a carriage-loaded printing cartridge, ensure reliability of a replenishment volume of ink and set a vacuum pressure at the printing cartridge, by changing a height of a storing container of the ink cartridge outside a shaft. ;SOLUTION: As a lot of ink is introduced in printing cartridges 70-76, a self adjustment replenishment process is started whereby a back pressure decreases to stop further replenishment of ink to the printing cartridges 70-76. A valve is engaged with a replenishment port of the printing cartridge. The ink is controlled by a distance by which the printing cartridges 70-76 and a storing container outside a carriage are biased slightly. As the storing container is set lower away from the printing cartridge 70-76, a final pressure in the printing cartridge 70-76 is increased and a volume of ink obtained in a storing container in the printing cartridge 70-76 is reduced.;COPYRIGHT: (C)1998,JPO
