Epson WF-3720 firmware update mode

Recommended Posts

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.

Some WF3720 printers can be put in firmware update mode in other way.

 

1. 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
