There are a few different ways you can clean your inkjet printer.
1. The printer utility. Refer to your manual for how to do this. Epson user manuals are located here.
3. Cleaning cartridges. Ryonet does not offer any cleaning solution or cleaning cartridges, however, this is an option. Inkjet printers use their inks clean the print head- unfortunately, this is all that the printer has to try and push out a clog with. There are companies that you're able to purchase cleaning cartridges and cleaning solution from so that when you notice print quality issues, you can swap out for the cleaning cartridges and use that solution to punch through the clog and save on your pricey ink.
