Hi momx4guys,
Thank you for the reply, and apologies for the lateness of mine, I was just being thorough :)
I will suggest that you start by running the HP Print and Scan Doctor. I would suggest running it for both Fix Printing and Fix Scanning and see what it has to offer.
If it is not able to resolve the issue, I would suggest clearing out your Temp folder (I realize it says it's for Windows 7, but the steps are the same for Vista) and then performing a Level 3 Uninstall to remove all of the HP software, and then downloading the latest version of your Photosmart C310a's software from HP's site and installing from that. If you use Internet Explorer to download the software make sure when it asks if you'd like to Run or Save that you choose Save.
Once this is done, you should have the right options again :)
