Automatic Duplex Printing not working

[Weepom]

Printer will not print automatic duplex.  Tried all the previous advice - checking auto duplex is installed, removing and re-installing drivers etc...  still no luck.    Help needed.

Thank you for posting on HP Forums,

As I understand, your printer does not print automatically 

No worries, as I'll be glad to help you, that said, I'll need a few more details to dissect your concern & provide an accurate solution:

When was the last time it worked fine?

Were there any hardware/software changes made?

Have you checked the print settings? 

While you respond to that, let's try these steps: 

• Right click on printer, select printer properties.
• Select the Device settings tab.
• Ensure that the duplex unit is set to Installed rather than Not installed.

If the issue persists, please perform a root level uninstall and reinstall of printer drivers: 

• Go to Control panel – Programs and feature – Select all the HP Envy printer entries and uninstall them.
• Now go to Control panel – Devices and printer – Select all the printer entries and remove the device.
• Then press the "windows key" + "r" to get the "Run" window open - Type "printui.exe /s" and press enter.
• Under print server properties, go to drivers - remove any entry there as well.
• Again, go to run window, type – “c:/programdata” – Go to Hewlett Packard folder, remove any printer related folders & files.

Note: You can skip these steps if you've already tried them 🙂

Keep me posted,

Cheers 🙂

Hi

Thanks for getting back to me.

I followed your instructions - but now in Device Settings the Duplex unit is showing as 'not installed'.  It is greyed out and it won't let me change to 'installed'.   I tried re-installing the printer but it didn't help.      The printer is new and was bought to replace an HP Officjet 3831.

Hello again.....

Its working OK now.  I repeated the instructions you gave above (again) but this time I installed printer using the CD instead of the link you supplied.  Works a treat.

Thanks again for your help.

I have a Envy 4520 that I installed last week.  It was duplex printing for a couple of days and now stopped.  I have tried all of the steps above (uninstalling everything HP related and reinstalling from the website) and ensuring that the Automatic Duplex Unit is installed.

Still not working 😞

Please help
