<p>Hi Guys,<br>
First off my apologies Howard, you are correct the cart does indeed contain 80ml when full and weighs 60-65 grams when empty. Since I posted this a short while ago I have since discovered that this is a common problem with this printer and the solution is to replace the head. As this is a pressurized system that requires the valves to work properly, and when they don't (remain open) then the ink is expelled from the cartridge and the display is unable to give a correct reading of the content amount. <br>
Pity.... I love the printer, guess I'll just have to find the nearest epsom repair agent and pay the ransom out. What a bummer!<br>
Thanks for the swift responses guys,.......much appreciated</p>
