Common problems HP Solution Center not working : Adobe Flash Player Error and Unable to scan
We would like to share some of the most frequently asked questions about HP Solution Center not working : Adobe Flash Player Error and Unable to Scan.

HP Smart Tank Plus 651
Microsoft Windows 10 (64-bit)

I tried the HP Full Software Solution for printing and scanning. It makes my HP 651 printer unusably slow.  How can I get scanning resolution above 300 DPI without the terrible slowness of the HP Full Software Solution for Printing?

Welcome to the HP Community Forum.


In general, Scanning above 300 DPI can be done using the printer glass (flatbed).


Having installed the Full Feature Software,

You have the option to install and use scan software and applications.


Whether scans are "faster" depend on the same sorts of criteria used by the full solution software.

For example, scan results are impacted by

  • Location of the data, that is, local computer, local network, cloud
  • The speed and health of your network,
  • Density of the data, that is the pixel count of the file(s) being scanned
  • The type of data (including whether data PDF as compared to Image) - speed might be impacted to data translation
  • Selected scan resolution.


Examples of scan options
