Do you have a HP Officejet 7610 A large format printer that will scan from your computer but if you try and use the console on the priner to scan you get the follwing error

The scan could not be completed due to one or more of the following reasons /
The scan could not be completed due to one or more of the following issue:
   - Connection to the computer is lost.
   - The application scans on the computer is currently in use.
   - OCR application is not installed on the computer.

You might also come across this when the printer is working fine and then seems to loose its settings.

Solution

Uninstalling the driver and re-installing it seems to fix the issue temporarily. The key to completely fixing this issue is as follows.

1. download the latest Full software package
2. uninstall all the printer software including the 3rd party packages that came with the printer software, this seems to be the key because i beleieve it is the 3rd party softwares that have the daemon/monitor that waits for contact from the printer. To find out what software was installed by the printer software if you do not know is to start the install of the new software package and then select custom install. The software list that then pops up will have greyed out options against software that is already installed and thus cannot be installed. What this means is the software that you cannot install is already installed and should be removed.
3. Make sure you reboot your computer after you have uninstalled the software.
4. install the latest software package for the printer and to be on the safe side run as administrator whilst your antivirus and firewall is completely disabled. This makes sure that all registry settings is installed correctely
5. check your USB cable is USB 2.0 rated and that the USB port you are using is supplying enough voltage.

Please note that Using the HP Connection Doctor seems to temporarily fix this issue but might perfom a permanent fix on some peoples PCs.
