Downloading and Installing
You can download NAPS2 from the download page. There are a few options:
- Installer (.exe) - For most users. Download and run this to install NAPS2 on your Windows computer. A shortcut will be placed in your Start menu.
- Installer for group policy (.msi) - If you are an organization distributing NAPS2 through group policy (GPO), download and install this. See Organization Use.
- Portable archive (.zip, .7z, .tar.gz) - If you want to use NAPS2 without installation, download and extract one of these files. Run NAPS2.Portable.exe to start.
Linux users must use one of the portable archives.
Creating a Profile
To scan with NAPS2, you need to create at least one profile. A profile stores a reference to a particular scanning device, and all the settings used to scan with it.
To create a profile, click the Profiles menu button, then click Add. Type a name for your profile, e.g. "Canon MP495 (color)".
There are two types of drivers: WIA and TWAIN. If you don't know the difference, try WIA. If you encounter problems (e.g. you can't find your device), try TWAIN instead. Once you've selected a driver, click Select Device and select the scanner you want to use.
Once you've selected a device, you can change the settings used to scan.
When you're done, click OK to save your profile. You can then create more profiles if you want, or press Done to go back to the main window.
Scanning
Once you've created a profile, you can now scan. Click the Scan menu button. If you want to choose a different profile, click the dropdown arrow instead. That's it! If you selected "Use native UI" in your profile, a TWAIN/WIA window will pop up allowing you to scan.
If you want to scan more pages, click the Scan button again.
Organizing Scanned Images
Once you've scanned one or more pages, they will appear as thumbnails in the main window. You can select thumbnails by clicking on them, and use the menu buttons to rotate/flip/reorder/delete them as required. You can also clear all scanned images and start over.
