Paper Tray Rollers

1. 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.
2. 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.
3. 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.
4. 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.
