Are you sure it is reporting the correct cartridge? Sometimes after you replace the cyan, it suddenly reports a problem and you assume it's the cyan you just replaced but it's actually a different one which came loose or is now empty. If it is a few months old, this is highly unlikely, unless you ran a firmware upgrade. How old is your printer? If it is brand new, there is a chance that Epson recently changed the programming again, in which case it is possible the cartridges are outdated and you need new chips. If it is a later cartridge, it becomes a little harder to diagnose. We even had 2 customers whose printers refused to recognize genuine Epson but worked with our reusables! I later found an explanation for that here: /Epson/E25.htm This indicates a broken pin in the printer or the failure of the recognition chip in the printer. At another client, the printer refused to recognize any cartridge - including genuine Epson. Removing the fragment solved the problem. This was shorting out the connection and causing the printer to fail to recognize any cartridge in that slot. At one customer (fortunately a local one) I used a flashlight and spotted a tiny fragment of a cartridge chip stuck to the pins inside the printer. Each chip is matched to its color and putting the wrong cartridge in the wrong slot will cause the printer to report an unrecognized cartridge.Īnother cause is a short within the printer itself. It usually means the wrong cartridge was inserted - such as a yellow in the blue slot. The chips they contain today are identical to the ones manufactured years ago.
Earlier epson printers and their matching cartridges have not been changed. I say this because so far, in the very few times this happened, the cartridges have always worked in another printer.
If more than one with any of the earlier cartridges (T048, T060, T069, T078, T079, T098), the problem is almost certainly with the printer. If this happens with one cartridge, it might be a bad chip.
