Is this possible ? I’ve gone through tons of ink trying to clear one single nozzle. It’s getting expensive, even with Piezoflush. I thought I could fill my flushing carts with distilled water with a dab of food coloring, or some RIT dye. Would this work ? The food coloring is water soluble. Or maybe a few drop of MK Ultra dark ink ? Then do Initial Fill after Initial Fill and try to unclog the nozzle… I haven’t seen anyone use vinegar. Could this work ? Or would the vinegar damage some rubber seals ?
