<p>A matrix printer having reciprocating print wires (12). The printing tips are arranged within a bearing (22). Ink is stored within a container (4) below the print heads. Wicks (44, 74, 75) deliver the ink from the container to the print wires by capillary action, depositing ink upon the sides of the print wires. The ink moves through the jewel bearing (22) and on to the printing tips and is transferred to the paper (15) by the tips. Porous absorbers (78, 79) expand upon wetting, to engage the print wires to regulate the flow of ink and prevent dripping or dribbling of the ink and to prevent the ink from travelling rearwardly along the print wires toward the print wire actuating means. The wicks are mounted in a holder (73) removably inserted into the nose (13) facilitating assembly and disassembly for replacement of the wicks (74, 75) and the porous absorbent means (78, 79). A separator tool (81) retains the wicks (74, 75) in position for proper insertion. The disposable container (40) is releasably mounted on a support (30) adjacent to the print head for ease of removal and replacement. </p> |
