Using the printer drivers and HP Scan utility downloaded and installed Jan 2018 I am unable to select duplex scanning.  I have a double sided doc in the ADF and scanning to PDF only captures every second page.

 

Note: double-sided copying via the ADF in one pass works flawlessly

Problem solved!  Download and install HP Scan Extended.  Available here:

I learned about it from this forum thread:
