Example: If you want to move ten cartons of paper from a storage area with a temperature of 90o F. to an operating area with a temperature of 70o F. (a 20o difference), you should do so at least 18 hours before using the paper.

Paper curl

Before the manufacturer cuts paper into sheets, it is stored on large rolls. After it is cut and packaged, it retains some of the curl from the rollers.

Although it is unnecessary to load paper with the curl facing up or down, best results occur when you are consistent. For example, if you open paper with the wrapper seam up, always load it in the tray that way.
