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 turn cartridges upside down; the toner inside the cartridges may
become caked or unequally distributed.
- Away from salty air and corrosive gases such as aerosols.
