There could be several reasons why your HP LaserJet Pro M404dw printer is not printing double-sided (duplex) pages. Here are a few troubleshooting steps you can follow:
1. Check driver settings: Ensure that the printer driver on your computer is set to enable duplex printing. Go to the printer properties or settings, and look for a "Print on Both Sides" or "Duplex Printing" option. Make sure it is enabled.
2. Verify printer's duplex capability: Confirm that your specific printer model (HP LaserJet Pro M404dw) supports automatic duplex printing. Although most modern printers have this feature, it's always worth checking the printer specifications or user manual to be sure.
3. Load paper correctly: Make sure the paper trays are properly loaded with the correct size and type of paper. In some cases, the printer may not recognize the paper as suitable for duplex printing, causing it to disable the feature.
4. Update printer firmware: Check if there are any available firmware updates for your printer model. Updating the printer's firmware can sometimes resolve software-related issues that might be preventing duplex printing.
5. Restart printer and computer: Try turning off the printer and your computer completely, and then turn them back on. Restarting both devices can sometimes resolve temporary communication or software issues.
6. Reset printer settings: You can try resetting the printer settings to their default values. Look for a "Restore Defaults" or "Reset to Factory Settings" option in the printer's menus.
7. Test with another document: Try printing a different document or file to see if the issue is specific to a particular document or file type. If it prints double-sided with other files, there might be an issue with the original document you were trying to print.
If none of the above steps resolve the issue, contacting HP customer support or referring to the printer's user manual for further assistance would be recommended.
