Duplex Unit setting randomly changed to "Not Installed"

[jerry_eco]

Have a Color LaserJet CP3505 with a duplex unit.  It worked fine on Windows 7 for years.  Upgraded to a Windows 10 computer and now having problems with duplex printing.  I set Printer Properties/Device Settings/Duplex Unit to "Installed" and after a few days it will go to "Not Installed".

I am using the PCL6 Class Driver.  When the printer was initially set up in Windows 10, "Query the printer and automatically select the driver to use" was checked.

Try testing with Universal print driver PCL6

I had tried "HP Color LaserJet CP3505 PCL6" driver from Properties/Advanced tab/New Driver.../Search Windows Update but it had major problems - print jobs would get stuck in the queue.  I will try the link you suggested.

The setting has stayed correct for long enough that I am confident that it is fixed now.  Thank you.

Is there a way to mark this thread resolved?
