The very common problem of 'epson ink cartridges cannot be recognised' is perhaps one of the most annoying and by far the most common cry from Epson printer owners. Believe it or not it is as common with Genuine inks as it is with compatibles. The problem can occur for a number of reasons and the simplest solution is this:
Epson Ink Cartridges Solution1. REMOVE ALL cartridges from the printer.
2. Turn the printer OFF at the wall, leave off for at least 20mins.
3. Turn the power back ON at the wall.
4. Turn the Printer ON and Firmly reinstall ALL inks.
Sometimes it can be that the ink cartridges are just not sitting inperfectly straight and not contacting properly with the printer contacts. Also check that the small microchips on the inks are all clean but be gentle with them and dont touch them with your fingers. If you continue to get the same message try replacing one cartridge at a time as more than likely one cartridge has a faulty microchip and this is the only method to isolate the faulty one.
Another common cause is also due to using a mixture of both Genuine and Compatible cartridges. It is recommended that you use either ALL Compatible Cartridges or ALL Genuine Cartridges in an Epson Printer. This way the Epson printer cannot detect the difference between the micro chips on the individual cartridges. Most people find that this problem is resolved by doing this.
