"error occurred while communicating with scanner" mac os x 10.8.2 with new hp 6700.

Question

device will not scan to computer.  returns "error occurred while communicating with scanner".  this error returns from the print/scan settings, from image capture and from the HP scan utility.  the printer will copy so the scanner will function to some extent.  it is brand new. on a wireless network.  prints fine
OS is fully up-to-date, drivers are current, downloaded from HP and installed rather than using CD.  device has been unplugged from wall, computer restarted, printers cleared and reinstalled.
any other ideas?
some more info...
if a sheet is placed in the scan feeder, the scanner illuminates and makes a ping sound.
firewalls are off
router has UPnP on
old printer, an hp6500, worked fine with identical setup
and a further note as I try to solve this...
the webscan function works from the printer web server
HP Utility does not have a Scan section.  HP Utility Applications has Scan 3.  this does not work

Hi BetterL8,
I understand your frustration. The software you are using was designed for the older operating system not for Mavericks. There has not been software released for the c310 that is compatible with Mavericks therefore, you will be using the Apples Print and Scan not the HP Scan. Because you have this old software still on the computer, I recommend you uninstall it and download the Apple Software Update. Follow the instructions below:
Scrub
Open the Applications folder > HP or Hewlett Packard folder > HP Uninstaller
Click continue, click on one of the printers in the list.
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 OK to 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 (this is good measure to ensure non of your permissions differ)
On the Dock, click  Applications, and then click  Utilities.
Double-click  Disk 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.
Restart the computer.
Check for apple updates
Connect the USB cable if it is not already connected
Click on the Apple icon
Select Software Updates.
Restart the computer.
Leave the printer on and unplug the power cable, reconnect after 1 minute.
