How To Update Brother Printer Firmware: A Comprehensive Technical Guide
Updating the firmware on your Brother printer ensures hardware compatibility with modern operating systems, mitigates security vulnerabilities, and optimizes internal print engine performance. The procedure involves utilizing the Brother Firmware Update Tool, which establishes a secure handshake between your local network or USB-connected hardware and the official manufacturer update servers.
Prerequisites and Necessary Equipment Preparation
Before initiating the firmware flash, ensure the integrity of the connection to prevent a partial write or memory corruption, which can lead to a non-functional or "bricked" printer. Firmware updates involve rewriting the non-volatile memory (NVRAM) of the printer’s main logic board. Failure to follow preparation standards can result in a hardware lockout that requires specialized service center intervention.
Essential Hardware and Connectivity Requirements:
A stable power source connected to an Uninterruptible Power Supply (UPS) to prevent power failure during the write cycle.
A wired USB 2.0 or 3.0 connection for the most stable firmware transmission, though high-speed local area network (LAN) connections are generally stable for wired Ethernet configurations.
A workstation running a supported OS version (Windows 10/11, macOS 11 or later) with administrative privileges.
The latest Brother Firmware Update Tool downloaded directly from the official Brother Support website, specifically matched to your printer’s model number and region code.
Estimated Duration and Operational Standards:
Download and Verification: 5 to 10 minutes.
Firmware Writing Process: 10 to 20 minutes (varies by file size).
Total Estimated Time: 30 minutes including device reboot and system initialization.
Compliance: Always verify the model name suffix (e.g., HL-L2350DW vs. HL-L2350DWXL) as firmware files are specific to exact regional hardware revisions.
Execution Workflow for Firmware Deployment
The firmware update process is standardized across most Brother laser and inkjet lines. It is critical to refrain from using Wi-Fi for firmware updates if the signal strength is inconsistent, as packet loss can lead to corrupted update segments.
Step 1: Identifying the Current Firmware Version
Access the printer’s internal menu through the control panel or the Web Based Management interface. Navigate to the Machine Information or Print Reports menu and generate a User Settings or Printer Settings report. Locate the section labeled Firmware Version or Main Firmware Version. Cross-reference this alphanumeric string with the latest available version on the Brother support portal for your specific regional model.
Step 2: Preparing the Workstation Environment
Close all active print queues, background printer utilities, and status monitors that communicate with the hardware. These applications often place locks on the USB or network port, which prevents the Firmware Update Tool from accessing the printer’s communication layer. Ensure the printer is set to its default state and is not currently performing an active print job or cleaning cycle.
Step 3: Running the Brother Firmware Update Tool
Launch the downloaded utility. The software will perform an automatic scan for connected devices. Select your specific printer from the detected device list. If the utility fails to find the printer, verify that the printer driver is installed correctly and that the device status is listed as Online in your computer’s printer properties menu. Once detected, the tool will compare the installed version against the manufacturer's server.
Step 4: Initiating and Finalizing the Write Cycle
Once the software confirms an update is available, click the Update button. The progress bar will indicate the transmission phase, followed by the actual memory writing phase.
Warning: Under no circumstances should you power off the printer or disconnect the data cable while the screen displays "Updating" or "Please Wait." A disruption here will irreversibly corrupt the printer's mainboard bootloader.
Pro-Tip: If the update stalls for more than 30 minutes, wait an additional 10 minutes before checking the printer’s control panel. Sometimes the network handshake takes longer than the software interface suggests.
Step 5: System Re-Initialization
After the tool reports a successful completion, the printer will typically restart automatically. Allow the device to complete its internal startup sequence, which may include a sensor calibration or initialization of the drum and toner units. Once the printer returns to a Ready state, print a fresh Device Settings report to confirm that the firmware version string has updated to the target version.

Technical Comparison of Update Delivery Methods
| Feature | USB Direct Connection | Wired Ethernet (LAN) | Wireless (Wi-Fi) |
|---|---|---|---|
| Reliability | Highest | High | Low to Moderate |
| Ease of Setup | Direct Plug-and-Play | Network Discovery | Configuration Required |
| Risk of Corruption | Negligible | Minimal | Moderate (Latency Spikes) |
| Recommended Use | Critical Updates | Standard Updates | Only if No Other Option |
Troubleshooting Common Update Failures
Device Not Detected by Utility:
- Root Cause: Active print jobs in the spooler or background monitoring software preventing hardware access.
- Actionable Fix: Clear the print queue, disable the Status Monitor via system tray, and ensure the printer is not connected to a network hub/switch that utilizes port filtering.
Communication Error During Transmission:
- Root Cause: Faulty USB cable or network interference.
- Actionable Fix: Replace the USB cable with a high-shielding version under 6 feet in length or switch the connection to a hardwired Ethernet cable connected directly to the router.
Update Freezes at 90%:
- Root Cause: Firmware verification timeout or network packet loss.
- Actionable Fix: Force-close the utility on the computer, power cycle the printer by unplugging it for 60 seconds, and restart the utility. If the printer boots into a "Firmware Update Mode" screen, re-run the tool immediately.
Frequently Asked Questions
Can I skip firmware updates if my printer is working correctly?
While optional for minor improvements, firmware updates are essential for maintaining security patches and resolving known compatibility issues with updated OS kernels. If your printer functions perfectly, you may choose to delay, but critical updates should be applied to prevent future connectivity degradation.
What happens if the firmware update fails midway?
If a failure occurs, the printer may enter a bootloader recovery state. Most Brother printers have a failsafe that allows you to re-run the update tool via USB; leave the printer in its current state and attempt to re-establish the connection from the utility.
Do I need to uninstall my printer drivers before updating?
No, you do not need to uninstall the printer drivers. The firmware update tool acts independently of the standard print drivers and communicates directly with the printer's internal controller board.
Are there regional firmware restrictions?
Yes, firmware is region-specific to comply with local energy regulations and cartridge chip standards. Using firmware from a different region will typically result in a "Wrong Region" error within the update tool and will not proceed.
Ensure your office infrastructure remains secure and functional by keeping your fleet of Brother printers updated with the latest manufacturer-certified firmware. Regularly auditing your hardware ensures peak performance and avoids unnecessary downtime during critical workflows.
