We are in the process of buying a used sublimation system from someone. They have an Epson 1280 with a continuous ink system. They haven't used it in about a year. They have bags of ink that are unused. We were thinking of upgrading to a new Epson 1400, and saw that ink was compatible from the 1280. Is the bulk system itself compatible as well? How long will ink last in the bags themselves? Are there any drawbacks from having the bulk ink system itself sitting unused for a year? Would I be able to do multiple self cleanings to "get it going" again? Any advice is welcome! Thank you!
