My HP Envy 5540 Keeps Saying Out of Paper- What to do?

I don’t know what to do with the out-of-paper notification on my HP Envy 5540 printer. The papers are fully loaded inside the input tray. The complete machine is working fine (no disturbance noise, no problem with trays). Even, I have used the new set of papers for printing. I have been through so many troubleshooting guides to fix the problem but nothing works for me. Please help me to fix this problem.

Hello Miss, First you need to load only 25 sheets inside the input tray. Then check the control panel message. If the problem persists then you need to find any hindrance around the paper width guides if there is any then fix it if possible. Moreover, for precise solutions follow the article to fix the HP printer says out of paper error but it has paper.
