Brand new HP Pro 7740 - says paper tray 2 empty or open

Brand new HP Pro 7740 - says paper tray 2 empty or open, but the correct paper is loaded and the tray is fully inserted. Why won't it copy or print?

@MatthewHE, Welcome to the HP Support Community!

Make sure there are no obstructions in the tray path.

Check for any cardboards/plastics or packaging materials inside the tray and the printer. 

Refer to this document to know how to correctly load the papers - Loading Paper, Cards, Envelopes

Also, perform the steps mentioned in this document - An 'Out of Paper' error displays, printer does not pick paper

By default, the printer draws paper from Tray 1. If Tray 1 is empty and Tray 2 is installed and contains paper, the printer draws paper from Tray 2. You can change the behaviors using the following features:

● Default Tray: Set the default tray from which the printer draws paper first when paper of the same size is loaded in both Tray 1 and Tray 2.

● Tray Lock: Lock a tray to prevent it from accidental use; for example, when you have loaded special paper (such as letterhead or preprinted paper). The printer will not use a locked tray even when the other tray is empty.

Note: For better experience, load only one type of paper in a tray. Tray 2 supports only plain paper.
