Our Epson 4000 doesn't get enough exercise and suffers frequent clogs.
This last time I ran the auto head cleaning the cycle completed and
three cartridges came up as "invalid." I'm not willing to throw away
$240, since the carts show full and they are almost new. I'd try a
power clean or another head cleaning cycle, but the printer won't run
with these carts.

Anyone know how to override the printer memory so it forgets these
cartridges? Do you have a suggestion for what I can do besides buying
three new 220ml carts?

Thanks,
Michael
