Common problems HP Solution Center not working : Adobe Flash Player Error and Unable to scan

OFFICEJET PRO 7740
Microsoft Windows 7 (64-bit)

When scanning sometime my 7740 will not recognize that I have documents in the feeder. It scans the empty flatbed instead.

I have the document feeder selected as the source in the Printer Assistant but it doesn't recognize they are there and scans the flatbed. It usually corrects after I've rebooted my PC and turned the printer off a couple of times.
