Just for amusement, you might be interested to know that I just ditched my
Epson all in one. ...

Arfa

I, too, had an Epson (850? 950?) with similar symptoms. Cleaned the heads
right until they leaked (printed some red when you only wanted yellow) --
ironically the opposite of the original problem (clogging).

After that I bought the cheapest Canon I could find (iP3000 for $50US) and
have been really happy with it. The non-US model of the Canon printers will
print CDs/DVDs but due to patent arrangement only Epsons will do that here.
But there is a hack to allow these US models to print now. Was that ever good
news...

Am prepared for the worst, and will probably go buy a Canon LED scanner if it
comes to it.

Thanks for your story.
