Designjet T790 Ink indication

HP Recommended
HP T790

I have a designjet T790 that shows that all the ink cartridges are at 99% even though they have been used (some are almost empty).  This has been an issue for quite some time and the cartridges have been changed a number of times - the indication on the control panel stays at 99% no matter how much ink is used.


Is there a fix for this or can the cartridge levels be manually reset/adjusted ?

Wish I could help but I have the opposite problem.  Put in new cartridges and they sometimes register empty and sometimes register full.  Same printer.


Firmware has been updated.
