Why isn't paper feeding or getting picked up through the paper tray?

I've tried everything: cleaning the rollers, checking for debris, hard & soft resets, software re-installations. Wireless, Fax, Scanner features are all working flawlessly. Printer was never put through its paces, new ink, we print a few pages a month. HP suggested I had a firmware virus, computer has been scanned for viruses, and firmware freshly reinstalled. It all started with a carriage jam, which I cleared, paper never fed through again.

Is anything visually wrong with the included picture?
