HP Color LaserJet CM4730 Multifunction Printer series - Manual (Page 135)

Print on both sides of the page (duplex printing)
Automatic two-sided (duplex) printing
Specify two-sided printing options in your software program or in the printer driver. If you cannot see
this option, use the following information to make the duplex printing options available.
● Verify that the printer driver is configured to show the two-sided printing options: automatic and
manual. To change or verify the configuration, click the Start button, choose Settings, and click
Printers and Faxes. Then right-click on the printer and select Properties. On the Device
Settings tab, verify that the duplexer is shown as installed and that the Allow Manual
Duplexing option is enabled.
● After the two-sided printing option appears, select the appropriate settings in the printer-driver
software, including the page and binding orientation.
● Automatic two-sided printing is not supported for certain media types:
● Transparencies
● Envelopes
● Labels
● Heavy, extra heavy, cardstock, and HP Tough paper
The maximum weight paper for automatic duplex printing is 120 g/m 2 (32 lb) bond.
● Automatic two-sided printing only supports the following media sizes:
● Letter
● Legal
● B5
● Executive
● 8.5 x 13
● A4
● Manual two-sided printing can support all sizes and more types of media, excluding transparencies,
envelopes, and labels
● If both automatic and manual two-sided printing are enabled, the MFP will automatically print on
two sides if the duplexer supports the selected size and type. Otherwise, manual duplex will be
enabled.
● For best results, avoid using rough-textured, heavyweight media when duplexing.
● When using special media such as letterhead or forms, place the media face down in tray 2, 3, or
4, with the logo to the left. Place special media face down in tray 1, with the logo feeding into the
MFP last.
