agov261 1 Report post Posted November 24, 2018 The instructions of the WF3720_chipless_manual_en.pdf say to press the power button and the top right corner of the display to put the printer into firmware update mode. However when I do this, it does not work, it goes to the normal home screen. The current version I have is CL22I6. Is there still any way to make this printer chipless? Thank you for your time.

Use more display area - press in right upper corner about 2 x 1 sm area - then press and hold Power button. 2. Wait about 20 seconds!!!! untill Power button blinks Blue - release all buttons - You will get in Program Update Mode - white color text Please reply if You had success 1 Share this post Link to post Share on other sites
