Hi All I have been operating a CIS on an 1160 with Gen 4 inks for almost a year, (with absolutely no problems) but I need to produce some promos on glossy stock so I have decided to get a replacement CIS to use with the plug n play inks. My question is, can I mothball the CIS I am not using for a future 1160 of for swapping back and forth on the same printer in the future? It seems to me in the past that nomorecarts sold a "Pro" system for using more than one ink on a single printer or is that a delusional idea from a past epson induced dream? Does anybody swap? Am I going to have to buy a replacement cart and use the tubes from my Gen 4 setup? With all you ingeneous folks out there I figure maybe someone has figured out some alternatives. Thanks in advance.
