PaperScan doesn't find my scanner.

Hello!

Today I installed PaperScan Free Edition v1.8.1, but when I try to scan, it doesn't find my scanner.
It's a HP Photosmart C4580 All In One printer and scanner connected over usb.
The pc is running Windows 7 and the scan and fax software in Win7 finds the scanner.
PaperScan only finds two devices, the webcam and a Minolta PagePro 1390 device.
The PagePro device was removed weeks ago, using the controlpanel, we don't have any PagePro scanner.

Please help me with ideas, how to fix it.

Thanks.

Hello,

It seems to be related to HP drivers, not directly to PaperScan software.
The first thing to do would be to change the acquisition standard from TWAIN to WIA to see how it goes.
You can change it in Options > Acquisition Standard.
Can you make the change and let us know?

Cheers,
Cedric

Also PaperScan is a 32-bit Software, therefore you have to ensure that the TWAIN driver installed in also 32-bit.

Best regards,

Thank you for your quick replies, changing to WIA, made it!
Now it works fine with my HP scanner.

Thanks,
Mat
