HP OfficeJet Pro 7740 All-in-One Printer, Scanner, Copier, and Fax up to A3

Scans and prints up to A3 size (inclusive). Features a tiltable display (located to the left of the tray; see first photo). Also includes copying, faxing, and web functionality. Condition: The scanner/digitalizer is immaculate and functions perfectly. The printer is not working, and I cannot determine whether this is due to needing a new ink cartridge. The display shows a warning message (see photos). I am selling due to lack of space. Pickup available in person in Cacém.
