Saved Scans Showing Blank

[JPinOH]

When I scan I can see it scanned correctly in the preview window but when I save the file as a PDF the result is blank.  This just happened recently...I've had this unit for years now.  But if I print to a PDF from the preview window the resulting file is fine.

If click the checkbox for "Long-term preservation (PDF/A) then it saves correctly; but I cannot choose this on "Scan to Computer"

I have a 6830 printer and recently starting having the same problem.  I scan a document, it shows correctly in Preview but when I save the file as a .pdf, the file is  always blank.  Don't what is causing this but as suggested below, when sending the file to a folder, I check the box "long  term preservation PDF/A" and now it saves the file correctly.  I am using a new Mac desktop.

Interesting that this is happening just recently. 

I was scanning from the controls of my HP OfficeJet to my Mac Desktop nine days ago.  The next day it did not work.  
Glad I found this thread!  
Now I need to access the printer from my computer to scan.  And, yes, I needed to click on "long  term preservation PDF/A" as I am saving the document for it to keep the scan.  
Wonder if this is an HP program  update issue?

Most likely a conflict with a recent IOS update and HP is probably not going to modify software for a printer that is no longer made.  Here is a work-around;  use Image Capture, a scanning app that comes with Macs and works with this printer.
