❏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.
