HP 8600 scan to OS 10.9.4 iMac

Question

Can't scan from HP 8600 to computer or network folder. Downloaded and installed latest drivers and can print wireless but iMac doesn't recognize the 8600 to scan.  Selecting Printer from System Preferences only gives options for scan to email and network folder which I can't make connection through HP directions. Select Spotlight on iMac and tye HP Utilities gives me a link to display for HP 8620 with icon for scan to computer but unable to select any function; cursor goes from arrow to plus sign when moved to HP 8620 display.

Hi @f4gib 
I believe the best appraoch is to complete a commplete uninstall, clean up of the Mac's disk permissions and a reinstall. From your description, it sounds to me like there is something in the software that is missing or not functioinng as it should. Please use the steps below to completed the recommended steps and let me know the outcome. Thanks.
Scrub/ Uninstall
Open the Applications folder > HP or Hewlett Packard folder > HP Uninstaller
Click continue, click on one of the printers in the list.
* Only do this step if you do not have any other HP Printers.  Hold down Control, Option and Command, While holding the three buttons down,
Click uninstall.
Reset Printing System
Click the Apple icon (   ), and then click System Preferences.
In the Hardware section, click Print & Fax/Scan. The Print & Fax/Scan  dialog box opens.
Right-click (or  Ctrl  +click) in the left panel, and then click Reset printing system…
Click OKto confirm the reset.
Type the correct Name and Password.
Click OK to reset the printing system. The Print & Fax dialog box shows no printer selected
Note: This will remove all printers in the print and Fax/Scan, any printer removed can be re-added later by clicking the plus (+) symbol.
Repair Disk Permissions
On the Dock, click Applications, and then click Utilities.
Double-clickDisk Utility.
Highlight your hard drive/partition on the left (by default this is "Macintosh HD").
Click the Repair Disk Permissions button at the bottom of the window.
Once the repair is complete, restart the computer and the printer.
Click on the Apple and check for Apple software updates, install the available updates and restart again. 
Now you can download and install the printer software and install it. >  Officejet-Pro-8600_v12.23.0.dmg
Although we just checked for Apple updates, please do so again, now that you have installed the HP software there may be an HP update available through the Apple software updater.
When you add the printer, please ensure you are using the HP driver, not the AirPrint driver.
Select Add other Printer or Scanner                                                       
Select the printer you are adding and next to 'Use' you select can the printer driver 
I hope this does the trick! Please let me know how this works out!
