I have an old Tektronix Colorquick 4696 inkjet printer with the good ol ink wells and I want to restore it. It works with an old Innovion / CASI futura II computer photography system from the 80's. Anyway I need to get the printer to do a clean cycle and I KNOW it had one, I just don't know what dipp switch settings were needed to make this happen. Also a list of the dipp switch settings or a manual would be very helpfull. (right now the unit prints yellow, blue and a strange dark green for black) On the same topic the unit uses a green maintenance fluid, which i'm going to run out of eventually and I am wondering if anyone knows of a good substitute OR better yet what this stuff really is? I would like to get my old futura up and running but it only works with a Balloonjet printer from around 1987 (no idea what that is) or a Tektronix 4696/4695. pictures of said system here @ colortron.tk Also general information on Innovion, CASI tech and their systems is always appreciated. Thank You For Any Information Ryan
