HP LaserJet Printers - Print Media Guide

If a signicant temperature dierence exists between the media storage area and the printer’s operating
environment, allow the media time to adjust to the temperature in the printer’s operating environment before
unwrapping it. The greater the temperature dierence and the greater the amount of media to acclimate, the
longer this time period should be. Allow one day for every 10°C (20°F) dierence in temperature between the
storage environment and the printing environment.
