Faulty HP Photosmart 6510 Four in One Wi-Fi printer (Harborne B32)

Hi all, this is a faulty HP Four in One Wi-Fi printer that was given to me recently, unfortunately it keeps insisting that there is no paper in the input tray ( when there is ) or it will just not feed the paper into the printer. I have cleaned the rollers but to no effect and it still does not work. On the one occasion when I did manage to get it going I was able to copy a toy logo which printed ok ( see photo ) so it would seem there is no problem with the ink printing side. I wondered if anyone wants to have a crack at getting it to work before its scraped. Kind regards Eric.
