As ink is ejected from a nozzle 16 of a jet printer, it either is sent on a control trajectory to the paper to effect printing or is directed toward a gutter for capture and recirculation. The exposure of the ink to the atmosphere and the fact that the open gutter 14 is exposed to the atmosphere provides the opportunity for contamination of the recirculated ink with microbes and bacteria from the atmosphere. The use of biocides has been favored in the past as a technique for controlling the microbial growth within the ink and ink recirculation system. This technique is one which requires that a material which is toxic to the microbes and the bacteria be added to the ink in minute controlled quantities.
