I've had this printer for about 5 years. I don't use it constantly and the photos we make from it are SEM photos for presentations. I last used it about 3 weeks ago, the cartridges were all partly used but none were giving empty warnings.
A few days ago I tried to print and I got a replace cartridge warning for all of the cartridges. I removed and reinstalled each cartridge but nothing changed. I contacted Epson tech support and they said it sounded like faulty cartridges and said they would replace them. I was dubious since they were working fine up to now. I had another new set and installed them with the same results with one addition, this time the printer dialog box warned me that I should use only standard Epson ink. It looks like it can't recognize the cartridges anymore and so thinks it is out of ink.
Anyone ever had this issue with an Epson printer? Is there any way to fix it? I'll do some googling but thought I'd ask here first.
