Abstract (en)
Drop-on-demand ink drop marking apparatus and method of the type employing a plurality of capillaries (8). The capillaries are coupled to a pressurized liquid source (16) to cause the liquid ink (6) to weep from the orifice (7). A drop (11) is formed by stimulating the ink in the capillary (8). High drop generation rates are possible because the weeping ink flow enables the liquid consumed in the process of forming a drop to be more rapidly replaced in the capillary than if capillary action alone is relied upon for the replacement. A laser scanning beam (10) reflected from a rotating polygon mirror (43) is one embodiment for stimulating the ink to cause its expulsion from the capillary, and into flight towards a target (4). The beam heats the ink to expel it. Alternatively, a solid state laser adjacent eah capillary is disclosed for stimulating the capillary to expel a drop into flight toward a target.
