EPSON T802 DURABrite Ultra Ink Standard Capacity Black Dual Cartridge Pack (T802120-D2) For Select Epson WorkForce Pro Printers Review

The description implies that it is standard ink. However, when I tried to install it, I received an error message stating that I installed an initial cartridge as opposed to a replacement cartridge. Since my printer is not brand new the ink cartridges are useless to me. I bought the dual pack so now I'm stuck with two ink cartridges that I cannot use.Seller needs to do a better job at disclosing this information up front.
