Paper curl 
Paper curl results from both the heating process used to bond the print 
image (toner) to the media and from the path that the media must 
negotiate through the printer.
Take the following actions to help reduce paper curl:
1 Turn the media over in the input tray. Some media 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 might yield more acceptable results than 
the standard “face-down” output bin. 
3 Protect the media from adverse environmental conditions prior to 
use. Media designed for laser printing has an initial moisture content 
of 4 to 6 percent, which is maintained as long as it is stored properly. 
After the media has been removed from its packaging, it will dry out 
or absorb additional moisture, depending on the environment. 
Excess moisture in the media will increase the amount of curl.
4 Try a different type or brand of media. Not all media is designed for 
laser printing.
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 might remain longer 
because the leading edge tends to remain in contact with the fusing 
roller for longer periods.
