It would be more correct to say that -series- of Epsons tend to take
the same size cartridge with different chips. The C8x all seem to take
the same design of cartridge, but it's different than the R2x0 and
R3x0, which is different than the 2x00 series, etc.
You can buy 3rd party chips for those printers so it would be possible
to just swap the chips. Either chips that require a resetter (only
$1.50 each for the chips, but about $30 for the chip resetter) or
"always full" chips that autoreset, cost $15 each.

The older models of Epsons are willy-nilly when it comes to
cartridges. Black cartridges may work in several different models, but
color cartridges were less universal. The 800, 850, and 1520 all used
the same black and color carts, the same black from that set also
worked in several other models, the 1270 and 1280 use their own
cartridges, the 1200 used another set (black in common with other
printers), the black and yellow tanks for the 3000 also work in the
5000, etc.
Some of the older Epsons are much easier to mod for thick PCBs.
Problem with the C8x and C2x0/3x0 models is that they don't have a
straight rear feed path available. Some of the older Epsons such as
the 1520 have a rear feed that should take less work to modify.
I'd be happier if the Canon inks worked for this. I have a stack of
BJC 6000 that have rear feed path, and as-is can feed a CD without
hitting the head.
