Windows 11 Upgrade Guide
Hi Everyone, hope to get some help on this one if possible.
Deskjet Plotter T790 Replacement Magenta and Cyan Print Head not being accepted.
Genuine HP product; Number 72.
Once replaced, machine carries out an 8 minute count down to sort itself out, then asks you to replace the print head once more.
Please can anyone advise a way forward?
