I have three comments on this:
(1) I wonder how much ink left over is "substantial". A $45 settlement doesn't indicate the court thought there is a huge swindle here. Does anyone know the technical details? For example, when they sell a 220ml cart do they mean 220ml total or 220ml usable? If the former, how many ml get left in the tank?
(2) OK, it was a US legal initiative, but despite what I said above, if this is a real issue perhaps Epson should offer the settlement to customers in other countries too?
(3) Epson has issued a firmware up-date in recent months which is supposed to provide better ink management at the bottom of the cartridges - perhaps to address this issue?
