Have Epson stylus photo 820. Is there a reliable method to clean tops of INK PORTS that go into print carts? Most holes around tops of ports are completely coated so not even visible. Don't know the print head itself is clogged. Tops of ports appear to have a series of tiny holes around the top, like a gas cook stove burner. Any suggestions on how to get the dried ink off tops of ports? Read about cleaning kit for PRINT HEAD, but would they work unclogging the port holes? If so, how? Would appreciate recommendations on specific kits, or other methods others have used. Thanks!
