not be funny but i would not doing ANYTHING to my printer if head of sales advice me to do
I would like to be contacted by engineer who knows what they doing really.... with respect to barbara.
DO NOT attempt any more cleans if you did them so many already.
cleaning heads feature is last resort only. it can damage your head and you wasting LOADS of inks. also waste tank is shrinking its capacity. So even if you menage to get it working dont forget about inks you used and waste ink tank. who will replace that??
better off try cleaning solutions over night or send printer back. so it can be fixed by PROS, waste ink tank cleaned and reseted and ink toped up.
