Paper Tray Rollers
Step 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.
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.
Step 2
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.
Step 3
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
Step 1
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.
Step 2
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.
Step 3
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.
Step 4
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.
