Printing on both sides of paper (optional duplexer)

The MFP can automatically print and copy on both sides of paper when an automatic duplex
printing accessory is installed. This is called duplexing or two-sided printing. The duplexer
supports the following paper sizes: Letter, Legal, Executive, A4, A5, Executive (JIS), 8.5x13,
and JIS B5.

The ADF has automatic duplex scanning, so you can automatically scan two-sided
documents. However, you must have an automatic duplex printing accessory installed to
produce two-sided copies.

Note

The automatic duplexer is included with the HP LaserJet 4345x mfp, HP LaserJet
4345xs mfp, and HP LaserJet 4345xm mfp.

For models that do not include an automatic duplexer, you can order the duplexer as an
accessory. See

The duplex cover that is located on the left side of the MFP must be removed when the
duplexer is installed. See the documentation that is included with the duplexer for installation
instructions. When duplexing very complex pages, additional memory might be required.
