153 Replacing Consumables
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 qual-
ity. 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.
