Replacing Consumables 81
Keep toner cartridges:
# In their packaging until you’re ready to install them.
# In a cool, dry location away from sunlight (due to heat).
The maximum storage temperature is 35° C (95° F) and the maximum
storage humidity is 85% (noncondensing). If the toner cartridge is moved
from a cold place to a warm, humid place, condensation may occur,
degrading print quality. Allow the toner to adapt to the environment for
about one hour before use.
# Level during handling and storage.
Do not hold, stand or store
cartridges on their ends or turn
them upside down; the toner
inside the cartridges may
become caked or unequally
distributed.
# Away from salty air and corrosive gases such as aerosols.
