Yesterday while printing my Epson Stylus Pro 7800 started to leak large amounts of cyan ink. Sort of 'launched' by the printhead moving. Really crap, ruined my print. Did cleaning (manual and via the driver) but nothing solved it. Seems the cyan is leaking at the printhead (maybe the damper or an o-ring seal?), the printer seems to print just fine - except for ink spitting damaging the print... Anybody had similar issues? Advise highly appreciated...
