Successfully updated Epson WF3720. First fw update, stuck at 97%, second try, 98%, third and fourth tries, 99%, never would finish. But pulled power, turned on printer and successfully activated. Thank you!
However I have to ask, how does a person now know when ink cartridges are low? Going to use refilled cartridges for a while but don't want to run dry and risk print head problems. What are ways to see or estimate actual ink usage? Seems it will always show 100%?
