Solved: Can Piezography K7 inks from one model printer be used in another model?

I’m considering tossing my problematic Epson 7600 and getting a used 3800 for Piezography. The question is this: can I use any of those 7600 inks in the 3800? (I have a lot of ink left over, including a full set unopened.)

Yes! All of the Piezography inks work on all models we support. There are only seven distinct shades of Piezography ink with Shade 7 being lighter than Shade 6. Therefore, even K7 as used in the 3800 can be used in the 7600 as well as the 1400 (although shade 7 is not used in a six ink Epson 1400/1430 printer.)
