Auto Duplexing on HP Color LaserJet Pro MFP M277

[MrsTeamS]

We have had our printer for awhile now and we love it.

Something has happened and the auto duplexing isn't working anymore.

I want to turn off the Manual Duplexing, but I can't figure out how to do it.  

I have followed the steps found here http://hp.care/2lEMdTe and the problem has not be resolved.

How do I turn off the Manual Duplexing?  

Thank you.

Hi,
Make sure the Automatic Duplexing option is enabled:

Enter Control Panel > Devices and Printers.
Right click the printer icon, then click Printer Properties.
Click the Device Settings tab.
Set the Automatic Two-Sided Duplex Accessory as installed and click OK to save the change.

Now Automatic Duplexing should become available.

Regards,

Thank you for the instructions.  

When I click on Printer Properties, I get an error message.

Function address ..... caused a protection fault.

(exception code 0xc0000005)

Some or all property page (s) may not be displayed.

That is as far as I can get.  

Any ideas?

It seems as the driver is currupted.

I suggest uninstalling the HP Software from the Control Panel > Uninstall a Program, then download and reinstall the latest software and drivers:
