D UPLEX ( DOUBLE - SIDED ) PRINTING
If your MFP has a duplex unit installed you can print on both sides
of the paper, to save paper, weight, bulk and cost.
> Only paper can be used for duplex printing, not
transparencies or other media.
> Use paper stock of 20-32 lb. (75–120 g/m²). If you
experience excessive curling with 20-24 lb. (75–90 g/m²)
paper, use 28 lb. (105 g/m²).
> Use standard sized paper stock only, e.g. A4, A3, Letter,
etc.
> Load the paper print side up. Ream wrappers are usually
marked with an arrow, indicating which is the print side.
> Paper can be fed from standard paper trays, including the
high capacity feeder if you have one, but not from the
multipurpose tray.
> Do not set the paper weight to Ultra Heavy.
> Do not enable the White Page Skip function.
