Which of the following routine maintenance procedures is MOST likely to reduce or prevent recurring paper jams in a laser printer?
Clean or replace the paper-feed rollers.
Update the printer's firmware to the latest version.
Calibrate the printer's toner-density settings.
Replace the fuser assembly.
Paper jams frequently occur when the paper-feed rollers become dirty, slick, or worn. Cleaning the rollers with a lint-free cloth and distilled water-or replacing them when the tread has worn away-restores the proper grip and feed pressure, helping the printer pull sheets evenly and preventing jams. Calibrating toner density or updating firmware can improve print quality or add features but will not correct a mechanical paper-feed problem. Replacing the fuser assembly addresses toner-fusing issues, not paper pickup faults.
