IMPORTANT – Do not update your printer
Please make sure to remove/deactivate your automatic update. When Epson sends you an update, it only changes the firmware of your printer. As a result, the compatible cartridges will not work and you will have to wait until we receive an updated chip. Meanwhile, you are then stuck to buying the original cartridges only!!!
If you need help to remove your automatic update, please contact us by email or by phone.
