ABSTRACT:
An ink delivery system employing capillary member for delivering ink from a container directly to the tips of reciprocating print wires for ink transfer to a print receiving medium. Adjustment is provided for regulating the surface contact area between an ink container capillary member and a print head capillary member to regulate ink flow in order to accommodate printing speed and compensate for any factors which may alter ink flow, whether they be to cause more or less rapid ink flow. In a preferred embodiment, the ink container capillary member is moved relative to the print head capillary member. The capillary members are comprised of a porous material. Adjustment of ink flow is simplified through the provision of an easily movable handle arm and cooperating serrated slot for simply and rapidly adjusting the interface between the cooperating capillary members through which interface the ink is caused to flow.
