From your list, it seems you have all the bases covered. Good to go!
What do you mean the "Cobra ink tanks" can't even be picked up by the printer? Do you mean the printer does not "recognize" the cartridges or it tells you the ink is not epson inks? You say disappointing and a waste of time and money so did you ever find out what the problem was or just shelve the printer and give up? I have a 1430 and WF7110 and use both the pigment and sublimation inks from Cobra with no problems other than occasionally letting the sub printer sit too long and needing head cleaning, but that's on me...and it clears up pretty easy.Old post, but did that setup ever work? I used the same, and the Cobra ink tanks can't even be picked up by the printer. Disappointing and a waste of time and money unfortunately. Anyone else struck this?
