HP DesignJet T730 Large Wide Format Printer Plotter F9A29A. However, it continually says "verifying" with a loading circlesee pics. We were unable to get past this message to the main menu, and so we were unable to test the printer. At first, t here was also a flashing blue icon on the control panel. However, when we plugged an ethernet cable into the printer, lights illuminated on the printer's ethernet port(see pics), and the icon stopped flashing. We received the printer from a client of ours. We do not know what is causing it to continually show this message or how to resolve the issue. Please see all photos - you will receive everything pictured, and nothing in addition. Power cord and ethernet cable both included.
