i have just installed a CISS system on my Epson R300 there is no dark blue and the light magenta is leaking and emptying over night, i have tried doing several clean and recharges but it's still the same. can anyone help
The magenta leak coud be due to the tanks being in a higher position than the printer, it is advisable to have the tanks sat at the side of the printer no higher than the cartridges.
