Epson heads are not user-replaceable. It requires a bit of software to
align the heads (and there's a voltage number written on the side with
a felt-tip pen) and a bit of work on a DOS computer to realign everything.
You can remove the head for cleaning. Take the cartridge out, there is
a spring that must be removed (careful!) and a screw. The ribbon cable
just pulls out, it's not locked in. Hardest part is getting the ribbon
cable back in.
Be careful not to move any of those levers around the head holder.
BTW, if you want to try it, the Epson UK site has that bit of software
on it. Another thing not available in North America... :'/
