 If the problem only occurs during duplex printing, check for torn paper
in the duplex tray, verify that the duplex tray is inserted completely
and verify that the back cover is closed completely.

tray.
 Open the back cover (face-up output tray) to let the printed paper exit
onto the face-up output tray.
 Choose Reduce Paper Curl mode in the printer driver when you do
not use our recommended paper.
