Find and lift out the all-in-one toner cartridge if your laser printer is newer and relatively inexpensive. Take out the imaging drum. It is usually a bright green or blue color. Grab each side of the drum; do not touch the surface of the drum. Carefully lift out the imaging drum and place it in an area with no light.
Rest the cartridge on another toner cloth.
Find the exposed fine wires inside the printer. They are usually near the paper rollers. Their purpose is to attract toner by transferring a static charge to the paper. Rub the swab across the wires, twisting the swab when one side becomes soiled.
