A start-up and shutdown system for removing unwanted ink from a continuous inkjet printer comprises a porous element in flow communication with a cleaning chamber, both positioned adjacent to an ink supply chamber and nozzle plate. The porous element absorbs the unwanted ink from the surface of the nozzle plate. A negative pressure source is further provided to draw the absorbed ink from the porous element via the cleaning chamber. In one embodiment, fluid valve porous elements are provided to form a transient barrier to errant ink fluid in the form of a fluid bridge during start-up and shutdown of the printer.
