Are you using OEM cartridge ink? If you're using bulk the pressure could be set too high. How is the nozzle test and printing? Are you just getting drips, or are you experiencing ghosting and drop out in the prints as well?

the ink running through the head was from cheap dampers, the valves in them dont shut off, so by the genuine dampers.
But now after getting ink on the head from the dampers leaking, i have a temp to low -5c on the print head and now head wont print.
