Brother printers are popular for home and office use, but sometimes they fail to appear on the network. When this happens, computers or mobile devices cannot detect the printer, preventing printing, scanning, or network features. A printer not being detected often signals a network communication issue rather than a hardware failure.
Common causes of a Brother printer not being detected on the network include:
- Printer and computer not connected to the same WiFi network or network band
- Disabled network discovery or file and printer sharing settings
- Firewall or antivirus software blocking communication
- Dynamic IP address changes causing inconsistent connections
- Outdated or missing printer drivers
- Router settings such as device isolation preventing local network communication
- Printer in sleep mode or powered off during detection attempts
Symptoms include:
- Printer does not appear in the list of available devices
- Print jobs fail or remain in the queue
- Error messages like “Printer not found” or “Cannot connect to printer”
- Printer appears offline even though it is powered on
Recognizing these causes helps you focus on the right troubleshooting steps to restore detection and network printing.
Step by Step Methods to Fix Brother Printer Not Detected on Network
Step 1: Verify Network Connection
Ensure the printer is connected to the correct network. Use the printer control panel to check WiFi status:
- For wireless printers, confirm the printer is connected to the same SSID as your computer
- Ensure the network band is compatible (most Brother printers use 2.4 GHz)
Step 2: Enable Network Discovery and Sharing
On Windows:
- Open Control Panel > Network and Sharing Center
- Click Change advanced sharing settings
- Turn on network discovery and file and printer sharing
- Save changes and restart your computer
On Mac:
- Go to System Settings > Printers and Scanners
- Ensure printer sharing is enabled
Step 3: Restart Devices
Power-cycle the printer, computer, and router. Restarting refreshes network connections and resolves temporary issues. Power on the router first, then the printer, and finally the computer.
Step 4: Assign a Static IP Address
Dynamic IP addresses can change, causing the printer to disappear from the network. Assign a static IP through the printer menu or your router settings to maintain a consistent connection.
Step 5: Check Firewall and Security Software
Firewalls or antivirus programs can prevent detection. Temporarily disable them and attempt to detect the printer. If successful, add the printer as an exception in the security settings.
Step 6: Update Printer Drivers and Firmware
Outdated drivers or firmware can prevent network detection. Download and install the latest drivers and firmware from Brother’s official website, ensuring they match your operating system.
Step 7: Reset Network Settings on the Printer
If the printer remains undetectable, reset its network settings:
- Navigate to Network > Network Reset on the printer menu
- Reconnect to the WiFi network using the Wireless Setup Wizard
Step 8: Test Detection on Multiple Devices
Try detecting the printer on another computer or mobile device to confirm the issue is not device-specific. If it works on one device but not another, the problem is likely on the client computer.
Common Causes and Solutions for Brother Printers Not Detected
| Cause | Symptom | Solution |
| Wrong WiFi network | Printer does not appear | Connect printer and computer to the same network |
| Disabled network discovery | Printer not detected | Enable network discovery and printer sharing |
| Dynamic IP changes | Printer intermittently disappears | Assign a static IP to the printer |
| Firewall/antivirus blocking | Printer cannot be detected | Configure firewall to allow printer communication |
| Outdated drivers/firmware | Printer not recognized | Update driver and firmware |
| Router isolation | Printer not visible to devices | Adjust router settings to allow local network communication |
| Printer sleep mode | Printer appears offline | Disable sleep mode or wake printer before detection |
Identifying the correct cause allows you to apply the appropriate fix quickly and efficiently.
Preventing Brother Printer Detection Issues in the Future
To prevent network detection problems:
- Assign a static IP address to your printer to maintain consistent visibility
- Keep firmware and drivers up to date
- Ensure all devices are on the same network and compatible band
- Configure firewalls and antivirus software to allow printer communication
- Avoid frequently changing WiFi passwords without updating the printer
- Restart network devices periodically to refresh connections
For shared printers in offices or homes, document network settings, IP addresses, and driver versions. This ensures all users can access the printer without detection issues.
By following these steps and preventive measures, your Brother printer will remain visible on your network, allowing reliable printing and scanning across all devices. Proper configuration, updated software, and consistent network practices are key to avoiding detection problems in the future.
