Question:
After an automatic firmware update, my Epson WF-7720 printer switched from a USA to a UK version, rendering my 252/XL cartridges unusable. It now requires 27/XL cartridges. Epson hasn't been able to help. What can I do to resolve this issue?
Answer:
Your Epson WF-7720 printer will face major incompatibility with its cartridges if a firmware update switches its region. Below are some methods to fix the issue:
Call Epson Customer Support
The easiest solution is to call Epson and tell them what's going on. It's not an uncommon issue, and Epson generally issues replacement cartridges as a goodwill gesture. Contact their customer support team and request assistance if you haven't done so already.
Reverse the Firmware Update
Reversing the firmware update can return your printer to its original region settings. There is a tool designed for such things as WICReset (https://www.wic.support/). It peels back the firmware, making the 252/XL cartridges you own fully compatible. Follow all directions carefully, as this is a zero-tolerance-to-error firmware adjustment.
Advanced Solutions
If none of the above are an option, there are other methods involving special software and hardware tools. However, these methods require strong technical knowledge and more gear. Use reputable resources or professionals to avoid added complications if you pursue any of these avenues.
