VueScan since the original drivers for my old Canon LiDE 210 dont work very I use Windows 10 with a 4K monitor and 200% scaling and just tried You can improve the UI somewhat by using the system DPI scaling of Windows for the application, but this will of course only change some labels and form elements, not the resolution of the scan preview: To illustrate this problem I enlarged a part of the Window where you can see the difference in the text of the title bar in native 4K resolution (which is handled by Windows itself) and the text of the menus and UI of the application itself: Process explorer shows that the executable is not DPI aware:Īnd the expected result when using VueScan on a 4K display with 200% scaling:

More about this, see this article from Microsoft. The only downside: the Windows 10 version is not DPI aware which means the UI and the scan preview will be rendered at a four times lower resolution and look quite grainy on a 4K display with 200% scaling which is a pity for an application of this kind. Overall this is a quite solid and useful solution and it’s good to see that you can still use your old scanners with Windows 10. The options include everything you can think of, depending on the capabilities of the scanner: different scan modes, adjustable bit depth, skewing, automatic scan with adjustable time interval (very useful, when you want to scan a lot of slides manually), cropping, a bunch of filters and output formats including PDF, JPEG and TIFF. The universal driver by VueScan does not provide a TWAIN or WIA interface since it only needs to work with VueScan itself – but on the other hand this also means it is much more stable. The first impression was quite good – during the setup the universal scanner driver was installed and after connecting my old scanner I could use VueScan right away. Therefore I decided to look for an alternative and tried VueScan – an application which comes with its own drivers.īefore installing VueScan I needed to uninstall the existing Canon software and the old driver and also tell Windows to remove the driver files as well, so the original driver would not be used any longer. Canon also provides drivers for Windows 10, but they cause the Windows WIA service to crash quite often. I have an older scanner – a Canon LiDE 210.
