HP C4780 printing error message

[YYYH]

The printer is Photosmart C4780. It always shows the error message “out of paper” despite all efforts I’ve tried fixing it. I noticed the front rollers were rolling but the back rollers were not, that’s probably why it’s not picking up the papers. The back rollers are cleaned and can be rolled when I roll them manually, but they are just not responding to the papers. I tried all the troubleshooting steps provided by HP official website but did not solve this problem. The printer is also out of warranty. Some help please?
