After using the print cartridges, no matter what, and I have all 10 durchbrobiert, the printer DX7000F always displays the error "Fehlerhadte cartridges / cartridges erstezen" According to On the bill taking the pins on the printer cartridges I could unfortunately only at the end of my efforts festellen that the pin placement of partons delivered differs from the pin placement of the original Epson cartridges. Perhaps it is indeed on the old printer Epson DX7000F!
