Edgar 0 Report post Posted November 18, 2019 I tried to recover one license in an XP-431 but the program show message Reading Failed - 1 I tried to re upload the firmware in IPL and in normal mode and still showing the same message. Are you going to upgrade the firmware for this printer? Best regards Share this post Link to post Share on other sites
