I have installed my CISS in the Epson printer exactly like instruction, but I don't get any result on the paper.
First, check the small tanks' plugs. They must be left open all the times after you installed the system.
Second, check the cartridges and make sure they are firmly inside the printer head. (If not you have to install the cartridges firmly).
Third, if your CISS use the tube locker, Please loosen the roller after you installed your CISS.
