Doug 0 Report post Posted November 18, 2019 I updated my xp 640 printer with the firmware successfully but cant get the activation code to work. Where do I enter into the activation app? Does the printer have to be in the update mode? Share this post Link to post Share on other sites
wic.support 30 Report post Posted November 19, 2019 Good day. If you mean chipless solution code, then activation software can be found at the top of this page: https://chiplesssolutions.com/download.shtml printer must be activated in usual mode. Share this post Link to post Share on other sites
Doug 0 Report post Posted November 19, 2019 By usual mode, you mean normal operating mode? I get an error when clicking <activate online> button. see attached picture. The printer is indicating firmware NK11JA Share this post Link to post Share on other sites

Doug 0 Report post Posted November 21, 2019 (edited) I tried again using the firmware link you sent. Still not working. The printer still show nk11ja. Does this mean that the printer will not accept the firmware even though it says it did.
