Managing your paper supply
NOTE: If there is a large amount of foot traffic in the paper storage room, the environmental control system may not be able to maintain the proper humidity level. Periodically check the humidity with an accurate humidity measuring device and adjust it up or down as needed.
•If an air conditioned room is not available, choose an area that is protected from extreme temperatures and humidity. Never store paper in temperatures below 50°F (10°C) or above 90°F (32°C). Relative humidity should never be below 15% or above 85%.
•Maintain print room relative humidity between 15 and 85%.
•Coated and specialty stocks are more sensitive to moisture than uncoated papers and should not be stored or used in environments exceeding 65% relative humidity, if at all possible.
•Leave reams and cartons unopened until you are ready to load the paper into the press. Ream wrappers and cartons are designed to protect paper from moisture. Ream wrappers have an internal moisture barrier that guards against moisture exchange. Once the wrapper is opened, the protective barrier is gone.
•If paper edges appear wavy or tight, return the paper to the supplier, or try changing the humidity in small increments (5 to 10%) and allowing the paper to rest in small stacks for several hours between changes.

•Follow any special instructions given by the paper mill or vendor.
•If you must use paper from an open, unsealed ream, take sheets from the center of the ream.
•Place opened paper in plastic bags or
Using storage bags for unused paper
Paper that has been unwrapped and not used, such as paper left over at the end of a shift, should be repackaged or protected with a moisture proof wrapper or plastic bag.
To help protect unwrapped paper, three storage bag kits are available for purchase from Xerox.
