Method and apparatus for replenishing an ink-jet head with ink.

摘要

An ink-jet print head has a supply reservior (10) filled with a spongy body (1) impregnated with ink. An ink replenishing device consists of a connecting element (32) made of porous material having one end immersed in a main container (48) separate from the head and the other end making contact with the spongy body (1) via an opening (30) in a wall of the supply reservoir (10). By to capillary action, when the spongy body (1) is partially empty of ink, the porous connecting element transfers the ink from the main container (48) to the supply reservoir. <IMAGE>
