Epson Inkjet Firmware Upgrades
Epson has released a number of firmware updates that are designed to block the use of third-party ink cartridges. The error message may say the cartridge is damaged or not recognized. Epson, among other manufacturers, has a tendency to push firmware upgrades intentionally to reject third party cartridges, thus forcing customers to buy the far more expensive OEM cartridges.
If you have one of the following printers and have upgraded the firmware, please follow the link to downgrade the firmware so you are able to continue using your third-party cartridges:
| Ink | Model | Link to Downgrade |
| T410XL020 T410XL220 T410XL320 T410XL420 T410XL520 | Expression Premium XP-530 XP-630 XP-640 XP-7100 XP-830 | Downgrade |

Please note: We now have the T288XL series in stock with up-to-date chips
If you have one of the following printers, a new firmware upgrade has been released and will disable the third-party cartridges from working. We do not have a solution just yet, but you can prevent future firmware updates by following the Disable link below:
