Updating firmware on WF-3720 in update mode

[Võ Quang Hưng]

Question about WF3720 printer firmware update​

Issue with instructions​

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.

Current firmware version​

The current version I have is CL22I6. Is there still any way to make this printer chipless? Thank you for your time.

Alternative way to put printer in firmware update mode​

Some WF3720 printers can be put in firmware update mode in another 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 until Power button blinks Blue - release all buttons - You will get in Program Update Mode - white color text.

Please reply if you had success.
