The Home series of VISTA do not include the builtin Fax and Scan
utility so you will have to rely on HP Software for that.
You must make sure you have the VISTA version of HP software for that
printer. You don't say which OJ6200 -- always give specific information
or you may get incorrect information.
Turn off the AIO and unplug the USB cable from the PC end.
I recommend that you go to:
and select which version printer you have and then the VISTA link.
Download the Full software (I hope you have broadband -- if not send
for the CD unless you are sure your CD/DVD has the VISTA version on it)
Use the Download / Save Option and not the Install Now or the Run
options so that you end up with the file:
in a folder you can locate on your PC. (I create a folder Internet
Downloads for this purpose and VISTA remembers once I've pointed it to
that folder and downloaded a file!)
Then download the fix "Critical update to prevent unexpected printer
uninstall" CIT223969-HPCOM-Baloo32-v4.exe and remember where it is on
After you have downloaded that, go to the Printers folder on the PC and
delete all the icons relating to the printer that are there; go to
Control Panel and select Uninstall a Program, look in the list for any
programs related to the HP AIO device and uninstall them.
Reboot the computer.
Then without the USB cable plugged into the PC, install the Full
Software by right mouse clicking on the first downloaded exe file and
selecting Run as Administrator and OKing your way out (probably ENTER)
Do not plug in the USB cable to the printer until the installation
software tells you to or until you reach Finish.
After you have done that and anything else it tells you to do, run that
Critical Update file in exactly the same way -- right mouse click on it
I hope that works for you.
