Printheads not working

HP Recommended
Designjet Z2100


We recently cleaned the printheads on our Designjet Z2100 because the colors were off and the quality was very poor.


After removing them and putting them back on we got a message to reseat the Yellow/magenta printhead. We did several time until it said it needed to be replaced.

We got the new printhead today and it still says it need to be replace and now it says another printhead (Light magenta/light cyan) also needs to be replaced. We replaced both but it keeps saying they need to be replaced.


Any ideas?

Clean contact between printhead and carriage.

Best regard
