Figure 3-2 Recommended temperature and humidity for
paper storage
Conditioning paper
Because temperature and humidity affect paper performance in
the printer, you need to condition paper before using it. To
condition paper, store it for a specified length of time in the same
type of environment as your printer.
The length of time you should condition your paper depends on
the amount of paper and the difference between the storage and
operating temperatures.
Use the following chart to determine the number of hours needed
to condition stacked cartons of paper.
NOTE: The numbers in the top two rows indicate the temperature
difference between the storage area and the operating
environment, not actual room temperatures.
