or this if you have Vista:
If you cannot find the scanner wizard it could be because your version of vista doesn't have it, I'm not 100% but I think it was only packaged with the business version of vista.
If this is the case then you can download a free program called IrfanView from there site: http://www.irfanview.com/
Click the Start icon. Click All Programs .
Click Windows Photo Gallery .
Click File and then click Import From Scanner or Camera .
Click Import .
Click Scan .

The user manual that came with the printer should explain how to do this.

get the Toshiba web page find your model and download suitable for win vista
the model c7183 is in the c1780 family so the driver and software will be the same for c7180 set of units

I had this very same problem yesterday & solved it, after about 4 hours, with a clean install!!
Check my "solution" post at another question where I explained it in detail.

Did the problem start after a Vista update? That's when mine started...

Hi damirish I have also been experiencing problems with the Scan To Computer button. I am currently in dialogue with the HP "head technician" who is due to ring me tomorrow. I will let you know what my resolution is. Basically, my problem is that my network (I use a netgear router) and have one wired (XP Pro) and two wireless PCs connected to it - one Vista laptop and one XP laptop. For some strange reason, the wired PC is happily displaying the correct Scan to file, Word etc functions yet my two wirelessly connected (Not the the printer itself but via wireless router) PCs appear multiple times and when I try to scan something to these two laptops, I get all kinds of errors. Even after running the HP clean-up tools and rebooting and reinstalling the HP software (32 bit) I now am faced with problems whereby the C7180 is not even recognised by the HP "Solution Center". Sadly, despite it's marvellous printing quality, I am thinking this unit is going back to the HP factory for some serious overhauling. Again, I'll let you know if there is a resolution and hopefully HP will investigate why the Scan settings are so faulty. Regards Andrew from Adelaide, Australia
