118 Maintaining Your Printer
• To achieve the best possible print quality, store print media in an
environment where the temperature is approximately 21°C (70°F) and the
relative humidity is 40%.
• Store cartons of print media on a pallet or shelf, rather than directly on the
floor.
• If you store individual packages of print media out of the original carton,
ensure that they rest on a flat surface so the edges do not buckle or curl.
• Do not place anything on top of the print media packages.
Storing Consumables
Store consumables in their original packaging until you need to use them. Do
not store consumables in:
• Temperatures greater than 40°C (104°F).
• An environment with extreme changes in humidity or temperature.
• Direct sunlight.
•Dusty places.
• A car for a long period of time.
• An environment where corrosive gases are present.
• An environment with salty air.
