1. Firmware Keys - don't have expiration date.

2. Activation Keys have expiration date.  If you want ActivationKey without expiration date - please contact us by PM - let us know how many keys and for what model do you need. Keep in mind - Activation Keys without expiration date (WED) are $5 per key more expensive.

Good day. Unfortunately WIC version of the firmware has been blocked by epson on loader level and could not be used with this specific device, you need to enable recovery firmwares in the settings and then update printer with recovery firmware to restore functionality. Then you need to use firmware from Chipless Solutions.
