If your printer told you that you needed to replace
all of the inks (rather than just one or two), it definitely suggests that there's a major fault with the printer. However, did you remember to press the button that starts ink charging after inserting the cartridges? (It's the one with the apex-down triangle).
Otherwise phone Epson on 01952 607 111 (0900-1730, M-F) or use the form here:
