My printer used to be able to auto duplex, and no longer does that since I upgraded to Windows 10.

My HP Envy 4520 printer used to be able to do auto duplexing before I upgraded my computer to Windows 10, and now the only way I can duplex is manually! Is there a way to get the  automatic duplexing function working again???

Edits - Correction to add the information for Adobe Reader DC

Upgrading the Operating System tends to kill off the printer software.  There are just too many changes in the OS for the printer software to "maintain" its hold.

Uninstall Existing Printer Software

Uninstall existing printer software from Programs and Features

Method One - Control Panel > icon view > Programs and Features >

Method Two - Settings > Apps > Apps and Features >

Search or Scroll down

Uninstall the printer software

After the software is removed, Restart the computer and log in

If printer software will not uninstall, appears to be removed and then shows up again, or is otherwise not “going away” when you tell it to do so, try an Uninstaller program.

Installation – Full Feature Software

NOTES

• If using USB, disconnect the USB cable between the printer and the computer before starting the installation.
• Connect the cable when instructed to do so (toward the end of the installation procedure).
• Some (newer) printer models provide the "Easy Start" install method. When applicable, Easy Start will be found in the Software and Drivers website support page > Category Software \

• Within Easy Start, you will be given the opportunity to install the software that is available.  Full Feature Software might be available – look for / Select the "Full Driver" software.

===============================================================

After the printer software is installed and the computer has been rebooted, things should go back to normal.

If not, check the duplex setup and a couple of other places...

Duplex feature installed? (Model Dependent)

Control Panel > icon view > Devices and Printers >

Right-Click Printer > Printer Properties > tab Device Settings >

Under Installable Options > Automatic Duplexing Unit > Select / Verify Installed > OK

Duplex feature in Printing Preferences (Model Dependent)

Control Panel > icon view > Devices and Printers >

Right-Click Printer > Printing Preferences

Select a shortcut that provides the feature and leave that shortcut highlighted (selected)

And / Or (if your printer software supported “custom shortcuts”)

Select a shortcut > Make changes that includes “Duplex” 

NOTES

• Remember to check the settings under each Tab
• Pay attention – not all Media (kind of paper) and / or paper sizes support Duplex

Save the changed shortcut settings with “Save As” (wording varies) to create a Custom shortcut

If you like, leave that (new / custom) shortcut highlighted as the “default”

Click Apply / OK to save the shortcut

Tray installed?   NOTE:  Likely not an issue - model dependent for printers providing more than one tray

Control Panel > icon view > Devices and Printers >

Right-Click Printer > Printer Properties > tab Device Settings >

Under Installable Options > Tray #  > Select Installed > OK
