So...when does the 560 demand printhead change?

[eahicks]

I don't think it has ever given a message to change one. I've changed a few simply because I deduced that one was causing bad prints.
Just checked my usage...should I let em be or start replacing?

Let it be unless you have printability issues.

We just changed head on one of our machines with 15000+ mls thorugh them

run the printhead diagnostic plot...replace only what you have to....it is a consumable after all.

 

[BIG EASY DOES IT]

Only replace when you notice it in the print. HP Tech support on the other hand. If you have print issues and you have to call them. They usually won't do anything until you are using up to date inks and printheads. Even if the issues doesn't have to do with the printheads.

I've got a few in in the 7-8 Liter range and they print fine. If you notice more graininess... change it, otherwise if the print quality is fine, let it be.

I wouldn't load a roll, hit print and walk away when theyre this high while printing a full roll, just incase one blows... which I've had happen.

sometimes they die early, sometimes they die really late, it's a gamble.

I think that I generally agree with the above advise... except with the Lc/Lm. Lc/Lm printheads notoriously die early and can ruin panels quickly,,,especially large solids.
It is generally advised to not run the Lc/Lm not much above 2L...especially if running solids. If I were running decals/stickers, I would run the Lc/Lm a bunch longer.
