Paper Curl
Paper curl is inherent to the laser printing processes, as it occurs when
paper is subjected to heat. Paper curl tends to relax as the paper cools while
resting on a flat surface. The specification for maximum paper curl when
the paper is lying flat before print is 5 mm (0.2 inches).
Although paper curl cannot be totally eliminated, some steps can be taken
to lessen its impact, as suggested in the following table.
Possible Cause Recommended Action
1. Paper Path Try using Tray 1 and output the paper to the face up bin.
2. Paper Surface The recommended printing surface of the page is usually marked on
the end of a ream of paper, indicated by a small arrow and the phrase
“print this side first.” Load paper in Tray 1 with the recommended
printing surface facing UP (facing down in Trays 2, 3, and 4).
3. Paper Storing and
Handling
Over time, paper assumes the characteristics of its storage
environment (in a humid environment, paper absorbs moisture; in a dry
environment, paper loses moisture). Paper with higher moisture content
will tend to curl more. Evaluate the storage conditions of the paper.
4. Paper Type All paper is manufactured differently (different textures, moisture
content, drying processes, composition, etc.). Change the type of paper
being used and re-evaluate the paper curl results.
