I bought refillable cartridges for the Epson XP-241 on AliExpress and did not work. The reason: Epson XP-241 manufactured in the Philippines. I was desperate. The solution: CHIPLESS. You've saved my XP-241 printer. Thank you very much.

This tool is badly wrtten, after downgrading using the wrong firmareware version I was unable to purchase another key as it thought it was a duplicate order, tried online help waited a hour and gave up, in total I have wasted £40 on a CISS system thats not reconized by the printer, and £20 on the WIC tool that although was my fault, I can remedy because I can't puchase another key
