9.Close the print head cover.

nathan_mills :

After removing the printhead, soak it in rubbing alcohol for 10 minutes, Remove it from the alcohol and shake it off then dry the head with a hair dryer with a COOL setting. Put it back to the printer, returne the cartridges, and performe a deep clean in the Maintenance settings.
