Please try this. The paper tray on the 477 has two length settings. One is for letter and one is for legal. Because the media pick system is in the back of the engine, the tray must extend out the front for legal. HP used to sell a small cover to make the tray look cleaner, but basically it sticks out an inch or two when the tray is extended.
Having said that, there is a small blue lever in the front of the tray a bit to the right of center. If you squeeze that towards the front of the tray and slide the two sections of the tray together, the tray becomes small size and when closed is flush with the front of the engine. Letter paper will still work with the tray extended becaluse it is held in by paper guides, but the tray sticks out and looks like it is not closed even though it is fully inserted.
Hope that is the problem (that is easy to fix). Please let us know.

I had this problem on our Color LaserJet Pro MFP M281cdw. While adding letter size paper, I inadvertently extended the paper tray to legal size. I could not adjust the tray back to letter size until I removed the stack of letter size paper. Seems like the tray has to be emply to enable this adjustment.

I finally got this figured out on my own -- playing around with various tabs and buttons, not really aware of what they were actually for. I have the user manual for this printer but could not find anything about this in the manual, which I found to be extremely limited and incomplete. Documentation for this printer is just awful.
