HP90 Print Heads - ink firing capacity

HP Recommended
HP Design Jet 4500 ps

Hello

 

I have a printhead that needs replacing.

 

I want to order the replacement but would like to know if others will need replacing in the near future. So as to order the one time.

 

How do I know if the others are close to needing to be replaced....or not.

 

I can see the "ink fired" ( in ml) information in the printer settings, but what numbers should tell me that they might soon need replacing also?

 

I have numbers in the 20ml range and others in 100 ml range.

 

Thanks Travis_D

HP warranty covers 1000 ml for 90 printheads, everything above that the printhead is not covered with warranty but that doesn't mean that printhead will not work after 1000 ml.

So the printhead should handle up to 1000 ml without issues.

The main problem is when the printer is not used on a regular basis and printheads fail way too early, the more you print and more often will keep your printhead in good health.

If you are satisfied with the print quality of a colour that printer doesn't need to be replaced.
