Hi Rachel,
I've followed the instructions in the first point, but unfortunately, I’m still getting no results. As for the second point, I checked the printer's firmware, and it’s confirmed as up to date. Regarding the third point, there is no paper jam or any obstruction.
The only step I haven't been able to complete is the fourth, as the error on my HP OfficeJet Pro 9730 remains on the screen and cannot be cleared, which means I cannot access the Settings > Printer Maintenance > Restore Factory Defaults section.
Could you please assist me, given that I live very far from the HP Office Center? It would take four days by boat to get there, and I urgently need to print. Thank you very much for your help.
Best regards,
Muin
