Whether you’ve just unboxed a new scanner or you’re trying to get an older one working with a new PC, connecting a scanner to Windows is usually a quick process — and in most cases, you won’t need to install anything manually at all.
Quick answer: For a USB scanner, plug it into your computer and turn it on — Windows detects and installs most scanners automatically within a minute or two. For a wireless or network scanner, connect it to your WiFi first through its own control panel, then add it through Settings > Bluetooth & devices > Printers & scanners in Windows. If it’s part of an all-in-one printer, Windows may need a moment to recognize the scanning function separately from the printing function.
This guide walks through both connection methods, what to do if your scanner doesn’t show up, and how to start scanning once everything is set up.
What You’ll Need Before You Start
| Item | USB Connection | Wireless/Network Connection |
|---|---|---|
| USB cable | Required | Only for initial WiFi setup on some models |
| Scanner powered on | Required | Required |
| WiFi network name and password | Not needed | Required |
| Manufacturer’s software (optional but recommended) | Optional | Recommended |
| Windows 10 or 11 | Required | Required |
How to Connect a USB Scanner to Windows
USB is the simplest and most reliable way to connect a scanner, and it’s the recommended starting point even for scanners that will eventually run wirelessly, since some models need a first USB connection to complete their initial wireless setup.
1. Plug In and Power On the Scanner
Connect the USB cable from the scanner to an available USB port on your computer, then turn the scanner on. Windows needs the device powered on to detect it — a common early mistake is leaving the scanner off while checking why it isn’t showing up.
2. Let Windows Detect It Automatically
In most cases, that’s all it takes. Windows recognizes the new device through plug-and-play, installs the necessary driver in the background, and the scanner becomes ready to use within a minute or two. You’ll typically see a brief notification confirming the device has been set up.
3. Add the Scanner Manually (If Not Detected)
If Windows doesn’t pick up the scanner automatically:
- Select Start > Settings > Bluetooth & devices > Printers & scanners
- Select Add device next to “Add a printer or scanner”
- Wait while Windows searches for connected devices — this can take a minute
- When your scanner appears in the list, select it and click Add device
Once added, the scanner appears in the Printers & scanners list and is ready to use from any app that supports scanning.
How to Connect a Wireless or Network Scanner to Windows
Wireless scanners take a couple of extra steps because the scanner needs to join your WiFi network before Windows can find it.
1. Connect the Scanner to Your WiFi Network
Most scanners handle this through their own touchscreen or control panel:
- On the scanner, open its network or WiFi settings menu
- Select your WiFi network from the list and enter your password
- Wait for the scanner’s WiFi indicator light to turn solid, confirming a successful connection
Some models require a temporary USB connection to a computer to complete this step through the manufacturer’s setup software, after which the USB cable can be disconnected entirely.
2. Add the Scanner Through Windows Settings
- Confirm your computer and the scanner are connected to the same WiFi network
- Select Start > Settings > Bluetooth & devices > Printers & scanners
- Select Add device, then wait for Windows to search the network
- Select your scanner from the list and click Add device
3. Install the Manufacturer’s Software (Recommended)
While Windows’ built-in detection is often enough for basic scanning, downloading the full software package from your scanner’s manufacturer (HP, Canon, Epson, Brother, and others all offer free downloads) typically unlocks additional features — higher resolution options, multi-page scanning to a single PDF, and more reliable reconnection after a network change.
Connecting a Scanner That’s Part of an All-in-One Printer
If your scanner is built into a multifunction printer, Windows sometimes installs the printing function but not the scanning function, or lists them as a single combined device without making the scanner clearly available to scanning apps.
To confirm Windows recognizes both functions:
- Go to Settings > Bluetooth & devices > Printers & scanners
- Select your printer from the list, then select Manage
- In the dropdown menu that appears, check whether an entry starting with “Scanner:” is listed alongside the printer entry
If no scanner entry appears, the fix is almost always the same: install the manufacturer’s full driver and software package rather than relying on Windows’ basic automatic driver, since the basic driver frequently covers printing only.
My Scanner Isn’t Showing Up in Windows — How to Fix It
If your scanner still doesn’t appear after trying to add it manually, work through these fixes in order.
Update or Reinstall the Scanner Driver
- Open Device Manager and look under Imaging devices or Printers
- If the scanner appears with a warning icon, right-click it and select Update driver
- If it doesn’t appear at all, download the current driver directly from the manufacturer’s support page and run the installer, which is more reliable than relying on Windows to find it automatically
Check Windows Update for Missing Drivers
Windows Update maintains a large library of device drivers separate from manufacturer downloads.
- Go to Settings > Windows Update > Advanced options > Optional updates
- Check under Driver updates for anything related to your scanner brand
- Install any listed update, then restart your computer and try adding the scanner again
Restart the Windows Image Acquisition (WIA) Service
WIA is the background Windows service that lets scanning apps communicate with connected scanners. If this service has stopped or frozen, your scanner can seem completely undetected even though it’s properly connected.
- Press Windows + R, type
services.msc, and press Enter - Find Windows Image Acquisition (WIA) in the list
- Right-click it and select Restart (or Start, if it isn’t running)
- Reopen Printers & scanners and check whether the device now appears
How to Start Scanning Once Your Scanner Is Connected
Once your scanner shows up in Windows, you have two easy ways to use it:
- Windows Scan app: a free, built-in app available from the Microsoft Store. Open it, select your scanner from the list, choose a file type (PDF or JPEG are the most common), adjust resolution if needed, and select Scan
- Windows Fax and Scan: an older built-in tool, accessed by typing “Windows Fax and Scan” into the Start menu search. Select New Scan, choose your scanner, adjust settings, and start scanning
If you installed the manufacturer’s own software, it usually offers more advanced options — such as scanning multiple pages directly into one PDF, or higher-resolution presets for photos — and is worth using for anything beyond a quick single-page scan.
Windows 11 vs Windows 10: What’s Different
The overall process is nearly identical between the two versions, with one main difference to be aware of:
- Windows 11: found under Settings > Bluetooth & devices > Printers & scanners
- Windows 10: found under Settings > Devices > Printers & scanners
Everything else — the Add device button, the automatic USB detection, the Windows Scan app, and the WIA service — works the same way on both versions. If you’re following instructions written for one version, only the initial menu path needs adjusting for the other.
Frequently Asked Questions
Do I need to install software to connect a scanner to Windows?
Not always. Most USB scanners are detected and installed automatically by Windows without any extra software. Installing the manufacturer’s full software package is optional, but it typically unlocks extra features like multi-page PDF scanning and higher-resolution presets.
Why isn’t my scanner showing up in Windows?
The most common causes are the scanner being powered off, a missing or outdated driver, or the Windows Image Acquisition (WIA) service not running. Restarting the WIA service and installing the manufacturer’s current driver resolves the large majority of cases.
How do I connect a wireless scanner to Windows without a USB cable?
Some wireless scanners can join your WiFi network directly through their own control panel menu, without ever needing a USB connection. Others require a brief, one-time USB connection to complete WiFi setup through the manufacturer’s software, after which the cable can be removed permanently.
Why does Windows detect my printer but not the scanner on the same device?
This is common with all-in-one printers when Windows installs a basic driver covering printing only. Installing the manufacturer’s full driver and software package, rather than relying on Windows’ automatic driver, typically adds the missing scanner function.
What’s the difference between the Windows Scan app and Windows Fax and Scan?
Both are free, built-in tools for scanning documents once your scanner is connected. Windows Scan is the newer app, available through the Microsoft Store, while Windows Fax and Scan is an older tool that also supports faxing on compatible hardware. Either works fine for basic scanning.
Can I connect a scanner to a laptop the same way as a desktop PC?
Yes. The connection process is identical on laptops and desktops — the only practical difference is confirming the laptop has an available USB port, or a USB-C adapter if it only has USB-C ports.
