Downside to pigment-based inks?

[Warren]

Now I'm hearing that carts for the Epson 2200 are only good for a few
months before the pigment inks "settle out" and become unusable. So
if this is the case, would it be advisable to remove them & give them
a good shaking every few weeks if the printer isn't being used?

My understanding is that with proper cartridge flushing, dye-based
inks may be substituted in the 2200, and it would seem that there are
applications for which dye inks might be more suitable. Any ideas?
And is anyone having good success refilling their 2200 carts?

I've had mine more than a year and it's ok. Sometimes I don't use it for two
weeks and it's still ok.

I don't bother.

inks may be substituted in the 2200,

If you can reset the chip in the cart.

The 2200 is an expensive printer to experiment with. Much better to do it
with a cheap one or buy a dye ink printer in the first place.

and it would seem that there are
applications for which dye inks might be more suitable. Any ideas?

Pigment inks don't dry as fast as dye based so it's much harder to print on
plastic (OHP film?). I recently tried HP glossy photo paper in my Epson and
it didn't work. The ink came off on the exit rollers. Same paper works fine
in my HP dye printer.

I quite like the results I get using TDK Pro quality glossy photo (270g)
paper in my Epson.

You can buy special roller lifters to deal with slow-drying non-Epson
papers. I paid about $18 for a set ordered off eBay. If you're
interested I can try and find the seller's contact info.
