HP OfficeJet 7500 e910 Scanner Lost Issues in Windows 7 x64

A client of mine has this all-in-one device that is constantly losing its ability to scan.  the device is connected via USB and we have changed both the USB cable as well as tried different USB ports. 


Printing has never been an issue; however, it seems after a few days, the scanner is no longer available. 


Errors are received stating the scanner is not connected.  Even the HP utility complains the both the WIA and TWAIN drivers are not working.  We've tried turning the device on and off, rebooting the computer, unpluggin the USB cable and every combination between.


The only thing that works, temporarily, is to totally uninistall all of it's drivers, delete the printer, and then reinstall the very same drivers (latest from the product web page).  It will then work for a few days and then back to square one.


Is this device just not x64 windows 7 friendly?  Any help would be greatly appreciated as we've had to go through the above steps over 6 times now.


TIA for any advice.

Hi JamesBarrett,


You may like to check whether there is any program such as, antivirus or firewall etc. blocking the sanner. For examples, if possible, switch off the antivirus and see it the scanner would work.


If it still doesnt work, please kindly collect the detailed user enviroment information and contact service and supports...

contact number varid by countries & products in the folloing list,

I take it this was never really resolved? I have the same issues on a Windows XP SP3 32-bit system. Un-installing and re-installing the drivers seems to fix the issue.
