This kit was advertised as a "repair" kit for printheads. The actual purpose is to flush and clean the nozzles of the print head. The included instructions clearly state that the product uses a clear plastic tube and a liquid solution to perform the nozzle cleaning process, both of which were not included in the packaging. The video instructions explaining the cleaning process had to be deciphered from a long website URL made up of alphanumeric characters on a small instruction sheet, and even then I stumbled upon the actual video through trial and error. I would try cleaning the injector if there weren't any missing parts from the manufacturer.
