There is no free utility?
That is correct, anyway this free utility is only available in the US I believe and works on Windows O/S, and only once for a very limited time, but don’t forget about your waste ink, it hasn’t gone away..
Lubrication points can be in lots of places and so should be well planed out first, but above all putting on the wrong lubricant can be more harmful than not using any, a squeaky printer can be very annoying but not harmful..

I just used the official epson waste ink reset program and it worked perfectly! You can find it here
