    • Keep nozzles wet by periodic color use.
Great if printer is used often to keep nozzles from getting plugged. A good solvent and cleaning method is needed or don’t leave the machine unused for more than a couple of weeks. Take it with you on a long trip, or find out how to replace the print nozzles. Mine has no yellow.
