HP Z6100 printhead lifespan?

[escortle]

Does anyone know how many ml should on average pass through a HP Z6100 printheads, before it needs changing. I thought around 2000 ml.
Any ideas? Thanks

Well, it's hard to tell exactly, I have a printhead that counted up-to 9533 ml. and stopped counting and still working normally, others need replacement after about 3000 ml. but my average for over 2 years now is 5000 ml.

The printhead warranty will be fully spent after 1200 mL, but you can realistically get two or three times that without any problems.
