Guidelines for printing on both sides of the paper
1
 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 properly, it may be curled. Remove the paper and straighten it. If the paper
continues to curl, replace the paper.
 When you use the manual duplex function, it is possible that there may be paper jams or poor print quality.
(If there is a paper jam, see Paper jams and how to clear them on page 146. If you have a print quality
problem, see Improving the print quality on page 160.)
Note
Make sure that the paper tray is completely inserted in the machine.
