Konica Minolta magicolor 2400W User Manual page 48

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.
