Guidelines for printing on both sides of the paper
2
 If the paper is thin, it may wrinkle.
 If paper is curled, turn over the stack, straighten it and then put it back in the paper tray or manual feed slot.
 If the paper is not feeding properly, it may be curled. Remove the paper, straighten it and turn over the
stack.
 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 Basic User’s Guide: Error and maintenance messages. If you have a print
quality problem, see Basic User’s Guide: Improving the print quality.
Manual duplex printing
2
The machine prints all the even-numbered pages on one side of the paper first. Then, the printer driver
instructs you (with a pop-up message) to reinsert the paper. Before reinserting the paper, straighten it well,
or you may get a paper jam. Very thin or thick paper is not recommended.
