● Do not open the drum protective shutter on the toner cartridge. Print quality may 

deteriorate if the drum surface is exposed to light or is damaged.

● Always hold the toner cartridge by its handle to avoid touching the drum protective 

shutter.

● Do not stand the toner cartridge on end, and do not turn it upside down. If toner 

becomes caked in the toner cartridge, it may become impossible to free it even by 
shaking the toner cartridge.

Do not place the toner cartridge in fire. Toner powder is flammable.
