Digital BW, The Print

I spoke with MIS tech support today and they stated that any of the cartridges for the Epson 1400 made before the 1430 was released will not work in the 1430. (That's me.) Apparently, after the 1430 was released, Epson made some kind of a change in the interface and the third party chips had to be modified. Upgrade chips are not being offered. A new set of six cartridge is $30, so this is not a big deal, just kind of a hassle. 

I'll use the 1430 for color printing, both Epson and MIS inks, and dedicate the 1400 to B&W printing using the old MIS cartridges, which I have loaded for C-6, UT14 and LK2LK. 

As for mixing Epson and MIS cartridges in the 1430, I don't know if this is really an issue. I have certainly mixed them in the 1400. I did it just last week when I ran out of Epson black and threw in the MIS black to finish a project I was working on. Not a whimper from the 1400, it just kept on going.
