IMPORTANT INFORMATION: Most compatibility problems with Epson printers are the result of mixing ink cartridges from different manufacturers. For maximum performance, and to make sure you can take advantage of the EXTRA ink in our cartridges, we recommend using only our ink cartridges in your printer. If this is your first time using our compatible ink cartridges, we recommend you purchase a complete set to install in your printer. Once installed you can then change individual colours as required.
