Brother Printer Error Code 67 — What It Means & How to Fix It

What Does This Error Mean?

Brother error code 67 indicates a problem with the printer's fuser unit. The fuser is the component that applies heat to bond toner onto the paper. A fuser error typically means it is not reaching the correct temperature, is overheating, or has detected a mechanical fault.

Common Causes

The fuser unit has reached the end of its rated life and needs to be replaced — fusers have a limited page count
The printer was powered on in a very cold room and the fuser took too long to reach operating temperature
A paper jam inside the fuser damaged the fuser rollers or heating element
The fuser unit is not seated correctly after being removed for a paper jam clearance
An electrical fault — either in the fuser itself or in the power supply that drives it — is preventing it from heating correctly

How to Fix It

Turn the printer off and let it cool for at least 10 minutes. The fuser operates at around 200°C (392°F) and can cause serious burns if touched immediately after use.

There is usually a warning label on the fuser unit itself. Take this warning seriously — fuser burns are painful and take a long time to heal.
Open the front cover and carefully check if any paper is stuck in the fuser area. The fuser is the assembly at the rear of the toner cartridge bay. Remove any jammed paper gently.

If the paper is tightly wound around the fuser rollers, do not force it. Forcing it can crack the fuser roller, making the unit unrepairable.
Remove the fuser unit. On most Brother laser printers, this involves releasing two blue or green tabs at either end of the unit and pulling it straight out.

Consult your printer's manual or a YouTube video for your specific model — fuser removal steps vary slightly between Brother models.
Inspect the fuser unit for visible damage — cracked rollers, burn marks, melted plastic, or paper debris wound around the rollers. If you see any of these, the fuser needs to be replaced.

You can order a replacement fuser unit directly from Brother (brother-usa.com/supplies) or from third-party suppliers. Make sure the part number matches your exact printer model.
Reinstall the fuser unit (or the new replacement) firmly until both tabs click into place. Close all covers, power the printer on, and run a test print.

After installing a new fuser, the printer may show a message asking you to reset the fuser counter. Follow the on-screen prompts to complete the reset.

When to Call a Professional

Error 67 is critical because the fuser is a high-wear consumable that must be replaced periodically. Brother sells replacement fuser units for most of their laser printer models. Fusers for mid-range Brother printers typically cost $40 to $100 depending on the model. Installing a new fuser is a user-replaceable operation on most Brother models.

Frequently Asked Questions

How many pages does a Brother fuser unit last?

Most Brother fuser units are rated for 30,000 to 100,000 pages depending on the printer model. High-volume office printers use fusers rated for the higher end of that range. You can check the current fuser page count by printing a configuration page from the printer's reports menu.

Can I replace the fuser myself or do I need a technician?

On most Brother laser printers, the fuser is designed to be user-replaceable. It typically takes 5 to 10 minutes and requires no tools. Brother includes instructions in the printer manual and also has step-by-step guides on their support website. If you are at all unsure, a local repair shop can replace it quickly for a modest labour fee.

Why is error 67 marked as critical if I can just replace the fuser?

It is critical because the printer is completely unusable until the fuser is repaired or replaced — no printing at all is possible. Also, if the error is caused by an electrical fault rather than a worn-out fuser, installing a new fuser will not fix the problem. In that case, you may need a more involved repair to the printer's power delivery circuit.
