Paper curl
Paper curl results from both the heating process used to bond the print
image (toner) to the paper and from the path that the paper must
negotiate through the printer.
Take the following actions to help reduce paper curl:
1 Turn the paper over in the input tray. Some paper packages (reams)
have an arrow indicating the preferred printing side. Experiment to
determine which orientation yields the least curl.
2 Try a different output paper path (if available for your printer). Using
the face-up output path may yield more acceptable results than the
standard face-down output bin.
3 Protect the paper from adverse environmental conditions prior to
use. Paper designed for laser printing has an initial moisture content
of 4 to 6 percent, which is maintained as long as it is stored properly.
Once the paper has been removed from its packaging it will dry out
or absorb additional moisture, depending on the environment.
Excess moisture in the paper will increase the amount of curl.
4 Try a different type or brand of paper. Not all paper is designed for
laser printing.
5 Heavy toner coverage can result in more curl.
Much of the paper curl that is induced by the laser printer fusing
process will tend to relax within the first 24 hours following printing.
However, the curl on the leading edge of the page may remain longer
because the leading edge tends to remain in contact with the fusing
roller for longer periods.
