Guidelines for printing on both sides of the paper

 If the paper is thin, it may wrinkle.
 If paper is curled, straighten it and put it back in the paper tray. If the paper continues to curl, replace the
paper.
 If the paper is not feeding correctly, it may be curled. Remove the paper and straighten it. If the paper
continues to curl, replace the paper.
 When you use the manual 2-sided function, it is possible that there may be paper jams or poor print quality.

the print quality on page 177.)
