If the printer has a duplex unit installed but does not print automatically on both sides of the page, check the driver/software settings on the computer to make sure the duplex settings are configured correctly.

These settings tell the printer how to print the page and will override any settings on the printer. The duplex option must be added in the driver and then turned on to enable it to function.

This is usually the case regardless of the data stream (i.e., PostScript, PCL) or operating system.  Please follow the instructions below.

IMPORTANT! The screen shots and descriptions below apply specifically to the Lexmark T630 driver for Windows, but the instructions are similar for any of the laser printers.



  1. First verify that the duplex option has been added under the Device or Install Options tab of the printer driver software.  To do this:
    1. Go to the list of installed printers on your PC, right click on the name of the printer affected, and select Properties, as shown.

    2. Click the Device tab. Note: This may be listed as the Install Options tab in some programs. 
    3. Most driver programs will have either an Update or an Ask Printer button. See the highlighted example in the picture below.
      Clicking this button instructs the program to check the printer's current configuration and settings. The program will then update the driver to reflect the current settings and installed items.

    4. If your driver program does not have an Update/Ask Printer button or if the button is disabled or does not work, you can add the duplex option manually.
      Select Duplex Option in the Available options list and click Add to move the Duplex option to the Installed area, as shown below.

    5. Click Apply and then OK to save your changes.
  2. Try printing again. If the printer still does not automatically print on both sides, make sure that the duplex function has been turned on in the Printing Preferences portion of the printer driver. To do this:
    1. Right click on the printer name in the list of installed printers and select Printing Preferences.

    2. Make sure you have selected one of the options in the Duplex area (highlighted in red below).  In other programs, you may need to select 2-Sided Printing instead.
      Note:  If the duplex option has not been added (see the earlier steps above), this option will be disabled (grayed out).

    3. Click Apply and then OK to save your changes.
  3. Try printing again. If the printer still does not automatically print on both sides, confirm that the paper type selected corresponds to the media actually loaded into your printer.  Do this through both the printer driver (Paper tab) and the printer operator panel (Paper Menu)
    IMPORTANT!  Labels and transparencies will print on one side of the page only  (simplex) regardless of the printer or driver settings.  If the media type is set to Labels or Transparency, change the setting to allow for duplex printing.
  4. If the printer still will not print on both sides, there may be a hardware issue with either the duplex unit or the printer. For more information, click here.
