HP Color LaserJet CM4730 Multifunction Printer series - Manual (Page 144)

To use two-sided printing:
● Verify that the printer driver is configured to show the two-sided printing options: automatic and
manual.
● 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.
