If your printer is not printing double-sided automatically, try the following steps:

1. Check Printer Settings: Ensure that your printer settings are set to double-sided printing.
   

   To do this, open the Print & Fax menu on your computer and check the printer’s settings.

2. Printing Test Pages: Try printing a test page to make sure the printer is working correctly.
   

   This will help verify that the printer is functioning as intended.

3. Paper Tray Settings: Make sure the paper tray settings are correct.
   

   Verify that your paper type and paper size is correct and that the paper tray is set to print double-sided.

4. Software/Driver Updates: Update the driver software for your printer.
   

   Visiting the manufacturer’s website for your printer is the best way to get the most recent software updates for your printer.

5. Try a Different Printer: If all else fails, try using a different printer.
   

   Printers vary in their ability to print double-sided, and using a different printer might provide the desired results.
