Check the fuser rollers. If they don't look smooth they may have overheated. You may also want to check for tiny shreds of paper stuck inside the fuser assembly or any damage to the rollers. That can cause the next paper going through to jam inside the fuser assembly. There is a limit to the lifespan on a fuser assembly so you may want to order a replacement. I just took a quick look and I don't know if iFixIt carries these but you can get a new one from PrinterTechs.com. I've had very good success with them. A word of advice though, if the printer you are trying to repair is the HP LJ Pro 400 M401 listed above check the installation instructions first on PrinterTechs.com before ordering. This looks like one of the HP models that requires you to completely dismantle the printer--covers, lid, doors, drawers, and disconnecting and reconnecting electrical connections. It may be more economical, including the value of your time, to consider a new printer. Good luck.
