Why Does a Brother Printer Scanner Show Offline?

A Brother scanner may appear offline even when the printer can still print documents. Printing and scanning use different services and drivers, so one function can work while the other fails.

Common causes include:

• Network connection problems
• Incorrect scanner settings
• Outdated Brother scanner drivers
• Windows Image Acquisition (WIA) service issues
• Firewall or antivirus blocking communication
• USB cable connection problems
• IP address changes on the network
• Corrupted scanner software

Identifying the underlying cause makes troubleshooting much easier.

Common Signs of a Brother Printer Scanner Offline Error

You may notice one or more of these symptoms:

• Scanner displays “Offline”
• Brother iPrint&Scan cannot detect the scanner
• Windows Scan reports no scanner found
• Scanner works intermittently
• Unable to scan over Wi-Fi
• Scanner not responding after a Windows update
• Computer cannot find the Brother device

If these symptoms match your situation, follow the troubleshooting steps below.

Restart Your Brother Printer and Computer

A simple restart often resolves temporary communication issues.

Follow these steps:

1. Turn off the Brother printer.
2. Shut down your computer.
3. Restart your Wi-Fi router if using a wireless connection.
4. Wait one minute.
5. Turn everything back on.
6. Try scanning again.

This refreshes network connections and clears temporary software errors.

Check the network connection.

If you’re using a wireless Brother printer, ensure the scanner is connected to the same network as your computer.

Verify the following:

• Printer is connected to Wi-Fi.
• Computer uses the same wireless network.
• Signal strength is stable.
• No VPN is interfering with communication.

If your router was recently replaced or its password changed, reconnect the printer to the new wireless network.

Verify Scanner Status in Windows

Windows may incorrectly mark the scanner as unavailable.

To check:

1. Open Settings.
2. Select Bluetooth & devices.
3. Click Printers & Scanners.
4. Choose your Brother printer.
5. Confirm the scanner is available.
6. Remove and re-add the device if necessary.

After reconnecting, test scanning using the Windows Scan application.

Restart the Windows Image Acquisition (WIA) service.

The WIA service controls communication between Windows and scanners.

To restart it:

1. Press Windows + R.
2. Type services.msc.
3. Find Windows Image Acquisition (WIA).
4. Right-click the service.
5. Select Restart.
6. Set Startup Type to Automatic.

Restart your computer after making changes.

Update Brother Scanner Drivers

Old or corrupted drivers frequently cause offline scanner problems.

Signs you need updated drivers include:

• Scanner disappeared after a Windows update
• Error messages during scanning
• Brother software not detecting the device
• Random scanner disconnects

Download and install the latest scanner driver and Brother software package compatible with your operating system.

After installation:

• Restart your computer.
• Restart the printer.
• Test the scanner.

Reinstall Brother iPrint&Scan Software

If the scanner software becomes corrupted, reinstalling it often restores normal operation.

Steps:

1. Uninstall Brother iPrint&Scan.
2. Restart the computer.
3. Install the latest version.
4. Launch the software.
5. Search for your Brother printer.
6. Perform a test scan.

This also refreshes scanner configuration files.

Fix USB Scanner Connection Problems

If you’re using a USB connection:

• Disconnect the USB cable.
• Wait 30 seconds.
• Connect directly to the computer.
• Avoid USB hubs.
• Try another USB port.
• Replace damaged cables.

Faulty USB cables can interrupt scanner communication while allowing limited printer functions.

Resolve Firewall and Antivirus Conflicts

Security software sometimes blocks scanner communication.

Temporarily disable your firewall or antivirus and test scanning.

If scanning works:

• Add Brother software as an exception.
• Allow scanner communication through Windows Firewall.
• Re-enable your security software.

Never leave antivirus software permanently disabled.

Assign a Static IP Address to Your Brother Printer

Wireless scanners can go offline if the printer receives a different IP address after the router restarts.

Assigning a static IP address helps maintain a stable connection.

Benefits include:

• Faster scanner detection
• Fewer offline errors
• Improved network reliability
• Better compatibility with multiple computers

This is especially useful in office environments.

Reset the Brother Printer Scanner Settings

If none of the previous methods work, resetting the scanner configuration may help.

General process:

1. Open the Brother control panel.
2. Navigate to Network Settings.
3. Restore default network settings.
4. Reconnect to Wi-Fi.
5. Reinstall the scanner on your computer.

You’ll need to reconnect the printer to your wireless network afterward.

Prevent Brother Scanner Offline Issues

Follow these best practices:

• Keep scanner drivers updated.
• Install Windows updates regularly.
• Use a stable Wi-Fi connection.
• Restart the printer occasionally.
• Avoid unplugging the printer while scanning.
• Use genuine Brother software.
• Assign a static IP address.
• Keep firmware updated.

Preventive maintenance significantly reduces scanner connectivity issues.

Quick Answers

Why is my Brother scanner offline, but the printer works?

Printing and scanning use different drivers and services. The printer driver may function correctly while the scanner driver or Windows Image Acquisition service encounters an issue.

How do I bring my Brother scanner back online?

Restart the printer and computer, verify the network connection, restart the WIA service, update scanner drivers, and reinstall Brother scanning software if necessary.

Why can’t my computer find my Brother scanner?

Common causes include network interruptions, outdated drivers, firewall restrictions, incorrect IP addresses, or corrupted scanner software.

Frequently Asked Questions

Can Windows updates cause Brother scanner offline errors?

Yes. Major Windows updates may replace or disable scanner drivers, requiring reinstallation or updates.

Does changing the Wi-Fi password affect the scanner?

Yes. The Brother printer must be reconnected to the new wireless network before scanning will work again.

Can antivirus software block Brother scanners?

Yes. Some security applications mistakenly block scanner communication. Adding Brother software to the allowed list usually resolves the issue.

Should I use USB instead of Wi-Fi?

USB connections are generally more stable, while Wi-Fi offers greater flexibility. For environments with frequent network interruptions, USB may reduce scanner offline errors.

How often should I update Brother printer drivers?

Check for driver and firmware updates every few months or whenever you experience printing or scanning issues.

Conclusion

A Brother printer scanner offline error is usually caused by network communication problems, outdated scanner drivers, Windows services, or software conflicts rather than hardware failure. By following the troubleshooting steps in this guide—including checking your network, restarting the WIA service, updating Brother software, reinstalling scanner drivers, and optimizing your connection—you can restore scanning quickly and reduce the chances of future offline issues. Regular maintenance and software updates will help keep your Brother printer and scanner working reliably.
