Brother Printer Error 71 is typically related to issues with the printer’s fuser unit or its connections. The fuser is responsible for fixing the toner to the paper by applying heat and pressure. When Error 71 occurs, it usually means there’s a malfunction in the fuser or its connection, or possibly a temperature problem. Let’s break down the causes, solutions, and preventative measures in detail.
Understanding Brother Printer Error 71
Error 71 indicates a fuser malfunction, which might be caused by a range of issues:
- Temperature Control Failure: The fuser uses a heating element to reach a specific temperature to bond the toner to the paper. If the fuser doesn’t heat up properly or overheats, it can trigger the error.
- Fuser Connections: If the cables or connectors linking the fuser to the main control board are damaged, disconnected, or loose, the printer may not be able to detect the fuser correctly, resulting in Error 71.
- End of Fuser Life: The fuser has a limited lifespan (usually between 100,000 to 200,000 pages). If it reaches its end of life, it might not function properly, triggering the error.
- Power Supply Issues: If the printer experiences inconsistent power or surges, it can affect the fuser’s operation.
- Paper Jams or Misfeeds: Any paper jams or debris in the fuser area can cause overheating or improper operation, leading to the error.
- Firmware Issues: Sometimes, firmware glitches or bugs can mistakenly trigger Error 71. This is less common but worth considering.
Troubleshooting Brother Printer Error 71
Follow these troubleshooting steps to resolve Error 71.
1. Restart the Printer
A simple restart can sometimes clear error codes that are caused by temporary glitches.
- Turn off the printer and unplug it from the power outlet.
- Wait for about 10-15 minutes to allow the internal components to cool down.
- Plug the printer back in and turn it on.
Check if the error persists. If it does, proceed to the next steps.
2. Inspect the Fuser Unit
The fuser is a replaceable part, and sometimes issues arise because it’s damaged or nearing the end of its life. Here’s how you can check it:
- Turn off the printer and unplug it from the power source to avoid any risk of electrical shock.
- Locate the fuser unit. This is usually at the rear or inside the printer, depending on the model. You might need to consult the printer’s manual to find its exact location.
- Check for any visible signs of damage or excessive wear. Look for cracks, burns, or tears in the fuser rollers.
- If you see any issues, the fuser might need to be replaced.
- Check the connectors between the fuser and the printer’s motherboard. If any connectors are loose or damaged, this could be causing the issue.
If the fuser appears fine and the connectors are secure, proceed to the next step.
3. Check for Paper Jams or Debris
Sometimes debris, small paper scraps, or a misfeed can obstruct the fuser unit and trigger Error 71.
- Open the printer and carefully inspect the paper path.
- Look inside the fuser area for any trapped paper pieces or other foreign objects.
- If you find any, carefully remove them without damaging the internal components.
Once cleared, restart the printer and see if the error is resolved.
4. Check for Power Supply Issues
Power surges or inconsistent voltage can disrupt the fuser’s operation. To rule this out:
- Check the power cord for any visible damage or wear. If the cord is damaged, replace it.
- Avoid using extension cords or power strips. Plug the printer directly into a wall outlet, as power strips can cause voltage fluctuations.
- Consider using a surge protector to protect your printer from future surges.
After addressing any potential power supply issues, restart the printer and check if the error persists.
5. Update the Printer Firmware
Sometimes, firmware bugs can cause hardware-related errors like Error 71. Updating the firmware can resolve these issues.
- Visit Brother’s official website and download the latest firmware version for your printer model.
- Follow the instructions to update the firmware. This process usually involves downloading the firmware to your computer and using a USB or network connection to apply the update to your printer.
After updating the firmware, restart the printer and see if the error is gone.
6. Replace the Fuser Unit
If none of the above steps work and you’ve confirmed that the fuser is nearing the end of its life or damaged, it’s time to replace it.
- Consult your printer’s manual for instructions on replacing the fuser unit. Most Brother printers have user-replaceable fusers, but some models may require professional assistance.
- When replacing the fuser, be sure to buy an OEM (Original Equipment Manufacturer) part to ensure compatibility and quality.
After replacing the fuser, restart the printer and check if the error is resolved.
7. Contact Brother Support
If you’ve tried all the above steps and Error 71 still persists, it’s time to contact Brother’s customer support. There might be a deeper issue, such as a defective control board or wiring that requires professional servicing. Be prepared to describe the steps you’ve taken so far, as this can speed up the troubleshooting process.
Preventative Measures
To avoid encountering Error 71 again, follow these maintenance tips:
- Regularly clean the printer. Dust, debris, and paper particles can accumulate inside and cause issues with the fuser and other components.
- Avoid overloading the printer. Constant heavy-duty printing can wear out the fuser prematurely. If your printing needs are substantial, consider a model designed for high-volume use.
- Use high-quality paper. Cheap or incompatible paper can increase the likelihood of paper jams and misfeeds, which can affect the fuser.
- Install a surge protector. Power surges can damage sensitive printer components like the fuser. A surge protector can safeguard your printer from these events.
Conclusion
Brother Printer Error 71 usually points to a problem with the fuser unit, whether due to a malfunction, connection issue, or the unit reaching the end of its lifespan. By following the troubleshooting steps—inspecting the fuser, checking connections, addressing power supply issues, updating firmware, or replacing the fuser—you can often resolve the issue. Regular maintenance and using high-quality supplies will help prevent future errors, prolonging your printer’s life.
