• Check to see that the paper is loaded with the correct side up. Some
packages of paper have an arrow on the label that points in the direction
of the top side of the paper. Load paper with this top side up.
If there is no arrow on the label, check the paper for curl. If a small
amount of curl is present, fan the paper in the opposite direction of the
curl to remove as much of the curl as possible.
• Follow the instructions in Chapter 2 to properly load paper.
5.5.2 Paper Storage
Observe the following requirements when storing paper:
• Always store unused paper in its original wrapping. The wrapping
protects the paper against humidity.
• Do not store paper directly on the floor, as floors are generally humid.
• Lay paper on a flat surface to prevent in-ream paper curl.
