Screen says cannot recognize the following ink cartridges, it lists all of them. There is no other button to push, Help.I replaced them all and rechecked them many times.

One other thing - I read somewhere else on the Internet that Epson printers do not always work with after market ink cartirdges. SO that might be your problem as well.

I am an Epson Artisan 800 printer owner. And, I by the genuine Epson cartirdges (not after market). And I get this same error almost everytime I go to repce an ink cartirdge. I think it is sometype of design flaw or bug in the printer. The only way I have been able to get this to work is to turn the printer off and then turn the printer on again. That usually clears the problem. In one or two cases, I had to reseat the catridge and cycle power a second time. Very aggravating. I wish Epson would fix the flaw.
