Managed to get hold of a hardly use Epson R390, still has the original
ink cartridges. 82N type.
But one was stuffed, was not seen by the printer chip was stuffed
Got a new cartridge and its working OK but most of the Cartridges are
almost empty.
Remove the Chip of the dud Cartridge and found that it connect to
another item that is held in by a spring.
It turns out how Epson checks the ink level, I always thought it was how
many clean cycles it goes through, no the small item actually weighs the
ink in the cartridge.
The small spring holds it hard against the 2 holes near the ink outlet,
this thing is square with 4 contacts, 2 are just link through's, plus
it has a silicon small rubber face to seal it.
So if you get a air lock in the cartridge it could show empty you just
shake it to get rid of the air lock.
