Hopefully that will make it an easy fix

(Also when you order a hp10, I've found the older the cartridge the better - but still only 2/3 work.)
So glad you still see this!

I made a terrible mistake, yes we are indeed using HP10 for 310! We have 2 earlier version and 1 brand new HP10.

Totally frustrated with the error. I inserted all 3 printheads (many times), still cannot get rid of the error. And I am not confident in breaking the hardwares apart.
