Question

I have just fitted new ink catridges to me Epson SX205 and it doe snot recognise that it now has ink. Each time I turn it on the display on the printer shows:
1: Flashing "power" light";
2: Two flashing red lights under the "stop" heading;
3. A flashing "E" alongside 'copies'; and
4. flashing "A4" light.

Please help me as it is driving me nuts!

Many thanks in advance
