Paper Tray Rollers
Turn off and unplug your HP printer. Pull out your printer's paper tray and locate the printer rollers on the paper tray. Each roller is gray or black, and they are made of rubber. Remove the rollers from the tray.
On HP inkjet printers, the printer roller is not on the paper tray; it is on the area inside of the printer where the paper tray slides into the unit. Remove the paper tray and sit your HP inkjet printer upright, so the paper tray area is facing upward, and then look for the printer roller.
Pour 1 tbsp. of isopropyl alcohol or clean water onto a lint-free cloth and scrub the paper or internal tray rollers with the cloth. Fold the cloth in half and repeat the cleaning process until the rollers are free of dust and debris.
Wipe the rollers with a dry, lint-free cloth to remove any remaining dust or debris. Let the rollers dry completely before sliding the paper tray back into your printer.
Internal Pickup Roller - Laser Printers Only
Turn off and unplug your HP printer. Open your printer's front door and pull the printer's toner cartridge toward you to remove it from the printer.
Locate your printer's internal pickup roller. The roller is gray or black, and it is made of rubber. Lift the roller upward, towards the front of your printer. Pull the roller gently out of the printer and lay it on a clean surface, such as a desk or workbench.
Pour 1 tbsp. of isopropyl alcohol or clean water onto a lint-free cloth and scrub the pickup roller with the cloth. Fold the cloth in half and repeat the cleaning process until the roller is free of dust and debris.
Wipe the roller with a dry, lint-free cloth to remove any remaining dust or debris. Let the roller dry completely before snapping the pickup roller back into place inside of your HP printer. Reinstall the toner cartridge and close your printer's door.
Assumed you have cleaned out the feeding slot and sprockets that turn the feeder wheels. Often there's some piece of paper or gunk. One option that likely applies to most printers -- from another HP online source: http://h10025.www1.hp.com/ewfrf/wc/document?docname=c00190540&cc=us&dlc=en&lc=en
Look for paper that might have jammed inside the product. Use a flashlight to carefully view the areas around the rollers. Remove all traces of paper found.
Wipe the rubber paper-feed rollers with a lint-free cloth lightly moistened with distilled or bottled water. Rotate the rollers up carefully to clean all the way around.
Look for the paper pick roller farther inside the rear access area.
The paper pick roller IMPORTANT : The paper pick roller is a bit more difficult to reach; however, it is the most important part to clean. Make sure to clean it thoroughly. If this roller is not clean, the issue will likely continue.
Clean the paper pick roller with a cotton swab moistened with distilled or bottled water. Apply a moderate amount of pressure to make sure that you remove all debris. Clean the roller thoroughly all the way around.

Hello Chris! Welcome to FixYa! If you are facing False Paper Jam error in your HP Laser Jet 1312nfi but If you cant see any obvious paper jams, try to look closely into the rollers or the inside. There could be some tiny paper shreds stuck within those rollers. Or there could be a tiny piece of paper blocking the printer's sensor and thus giving you a false paper jam error. The rollers should be cleaned if the paper fails to feed smoothly into the unit. All document and media rollers should be cleaned using a lint-free cloth lightly moistened with water.
1. Turn Off the printer and unplugged power before cleaning the rollers. This will allow the rollers to be turned by hand in most cases. 2. Remove the rear access door to access the rollers. Clean any dust and debris from the rollers. 3. Open the back of the printer and check metal paper rollers (not the rubber rollers) in the interior of the printer. They should be clean and move freely. If these are not bright and shinny or have buildup on them, they should be cleaned. Also clean any dust and debris off of the rubber rollers. 4. Close the back cover and reattach the rear access door. 5. Plug the power cord back in and power the unit up. It should reinitialize for about 20 seconds. 6. Print another extended self-test page. After following these steps carefully, False Error message will be disappeared. I hope this solution helps you Let me know if you have any confusion in your mind.
Sir, Your Rating as FIVE Stars for this solution and words of appreciation will be esteemed Thank You for taking my service Concerned: Muhammad Uzair
Most cases on that machine it's the transfer roller that does that at 75mm, but could also be drum cartridge or fuser. Use a flashlight and inspect the fuser, shouldn't be toner or image on fuser rollers, If you unplug the machine when the print is in the middle, you can tell if it's before or after the fuser, and after the drum.
Most likely a charge roller or high voltage power supply. If you tried a new toner cartridge and that didn't work, check all metal contacts inside the printer (with the power unplugged) and wipe clean. not sure about this printer's FRU's, or if the charge roller is in the toner cartridge itself, but if there's a roller inside the printer with a metal contact, make sure its seated correctly. All the contacts meet at a high voltage board that can go bad, but if there's toner everywhere, i would try cleaning and a new toner cartridge. Good luck!
Change the gears , coz when the machine load or when you are printing the roller turn, and those roller has gears at the ends so when they are died they give those sounds, open the cover and try to detect which gear make this noise and change it.
Papper never realy "jams" the problene is usualy that the paper is late reaching the next paper sensor. What i would sugest is that you clean the paper pickup roller it is usualy in the shape of a D. Clean it with dishwassing soap dont use water just clean soap rub it on with a clean cloth until the roller is dry so use a small amount. This should solve your prbleme.
