Your printer has special firmware , which is not normal for wide use!
Thats  why please download  firmware version here - 



Upload firmware to  printer in normal mode (just turn on with normal button ) - dont put printer in Program Update mode.
The uploading process can be stopped about 70-90%- it id ok, do not pay attention.
Now please in task manager  window  stop update process.
WF3720 printer will blink for few minutes, then  it will power off.

Now power on the printer - chipless firmware is installed now in your printer!

I hope it can work. If any help, write us.. thanks!
