Next re install the cartridges and keep printing untill you are satisfied with the print quality.
You can leave this for several hours or even overnight untill all dried ink inside the printhead is dissolved. Simply remove the cartridges and spray some Windex in the offending holes where the ink flows into the printhead itself. Windex consists of around 50% ammonia which is the key ingredient for cleaning the printhead. Although it sounds odd "Windex" (window cleaner) can actually be used to break down the dried ink which remains inside of the printhead. The Epson printhead cannot be removed which makes cleaning an even more difficult task.
This happens regardless of the type of ink cartridges used and can just as easily occur with genuine or compatible printer ink. Epson Printers are renowned for clogging the printhead.
