    ❏Never force the product’s components into place. Although the product is designed to 
    be sturdy, rough handling can damage it.
    ❏When handling a toner cartridge, always place them on a clean, smooth surface.
    ❏Do not attempt to modify a toner cartridge or take them apart. They cannot be refilled.
    ❏Do not touch the toner. Keep the toner away from your eyes.
    ❏Do not dispose of used toner cartridge, photoconductor units, or fuser units in fire, as 
    they can explode and cause injury. Dispose of them according to local regulations.
    ❏If toner is spilled, use a broom and dustpan or a damp cloth with soap and water to 
    clean it up. Because the fine particles can cause a fire or explosion if they come into

    ❏Wait at least one hour before using a toner cartridge after moving it from a cool to a 
    warm environment to prevent damage from condensation.
