sensitive drum inside the toner cartridge. If the drum is exposed to light, this
can cause printing quality to deteriorate.
½ Handle the toner cartridge with care. Do not subject it to shock or vibrations.
½ Always set toner cartridges down with the arrow on the cartridge facing up.
Storing Cartridges
½ Store a toner cartridge in the original box and protective bag until you are
ready to install it.

35gC. Do not store cartridges in places subject to extreme fluctuation of
temperature or humidity.

not store it upside down. If the toner becomes caked as a result of being
stored in an odd position for too long, it may be impossible to dissolve it
completely even by shaking the cartridge.
½ Do not store the cartridge in salty or corrosive air.
½ Never attempt to disassemble a toner cartridge or attempt to refill it.
