If your Brother printer displays Brother Printer Error 46, it usually means the printer has detected that its internal waste ink absorber is full. While this message may seem alarming, it doesn’t necessarily mean your printer has reached the end of its life. In many cases, the issue can be resolved through maintenance mode, resetting the purge counter, or replacing the ink absorber if needed.

Whether you own a Brother DCP, MFC, or InkBenefit printer, this guide explains what Error 46 means, why it occurs, and the safest ways to fix it. You’ll also learn when a reset is enough and when hardware maintenance is required.

What Is Brother Printer Error 46?

Brother Printer Error 46 indicates that the printer’s purge counter has reached its preset limit. Every time the printer cleans its print head, excess ink is collected inside an absorbent pad called the waste ink absorber. The printer tracks these cleaning cycles using the purge counter.

Once the counter reaches a specific value, the printer stops operating and displays Error 46 to prevent ink overflow inside the machine.

Although the printer may still be mechanically functional, Brother blocks further printing until the issue is addressed.

Common Causes of Brother Printer Error 46

Several factors can trigger this error.

Full Waste Ink Absorber

The absorbent pads have collected enough waste ink that they may no longer safely absorb additional ink.

Purge Counter Limit Reached

Even if the pads aren’t physically saturated, the internal purge counter may have reached its programmed limit.

Frequent Print Head Cleaning

Running multiple cleaning cycles consumes ink quickly and increases the purge counter.

Heavy Printer Usage

Printers used daily for large print volumes naturally reach the maintenance threshold sooner.

Long-Term Ownership

Older Brother printers often display Error 46 simply because years of automatic cleaning have accumulated.

Symptoms of Brother Printer Error 46

Before the error appears, you may notice several warning signs.

• Printer stops printing unexpectedly
• “Unable to Clean 46” message
• “Machine Error 46” displayed on the LCD
• Print head cleaning fails
• Copying and scanning may be disabled on some models
• Buttons become unresponsive

Once Error 46 appears, restarting the printer usually does not solve the problem.

How to Fix Brother Printer Error 46

The correct solution depends on whether the waste ink absorber is actually full or only the purge counter has reached its limit.

Method 1: Restart the Printer

A simple restart won’t usually clear Error 46, but it’s worth trying before performing advanced troubleshooting.

1. Turn off the printer.
2. Unplug the power cable.
3. Wait one minute.
4. Plug the printer back in.
5. Turn it on again.

If the error remains, continue with the next method.

Method 2: Reset the Purge Counter

Many Brother inkjet printers allow technicians to reset the purge counter through maintenance mode.

General process:

1. Enter Maintenance Mode (steps vary by model).
2. Navigate to the Purge Counter menu.
3. Reset the purge value.
4. Exit Maintenance Mode.
5. Restart the printer.

Important: Resetting the purge counter without replacing a saturated waste ink absorber may eventually allow excess ink to leak inside the printer. If the absorber is physically full, replace it before resetting the counter.

How to Replace the Waste Ink Absorber

If your printer has been heavily used, replacing the waste ink absorber is the recommended long-term solution.

General steps include:

1. Turn off and unplug the printer.
2. Open the printer housing.
3. Locate the waste ink absorber pads.
4. Remove the saturated pads carefully.
5. Install new absorber pads.
6. Reassemble the printer.
7. Reset the purge counter.
8. Test print several pages.

Replacing the absorber helps prevent internal ink leaks and restores normal operation.

Brother Printer Models Commonly Affected

Error 46 can appear on many Brother inkjet printers, including:

• Brother DCP-J105
• Brother DCP-T220
• Brother DCP-T420W
• Brother DCP-T520W
• Brother DCP-T720DW
• Brother DCP-T820DW
• Brother MFC-J430W
• Brother MFC-J480DW
• Brother MFC-T910DW
• Brother InkBenefit series

The maintenance procedure varies slightly by model, but the underlying cause remains the same.

Preventing Brother Printer Error 46

While this maintenance error cannot be avoided forever, proper printer care can delay its occurrence.

Recommended practices include:

• Print regularly to reduce excessive cleaning cycles.
• Avoid unnecessary print head cleanings.
• Use genuine or high-quality compatible ink.
• Keep the printer powered on if used frequently so automatic maintenance runs efficiently.
• Perform nozzle checks before running multiple cleaning cycles.
• Clean the printer exterior regularly.
• Schedule periodic maintenance for high-volume printers.

Proper maintenance extends printer life and reduces downtime.

When Should You Contact Professional Repair Services?

Consider professional service if:

• Error 46 returns immediately after resetting.
• Ink is leaking inside the printer.
• The waste ink absorber is completely saturated.
• Maintenance Mode cannot be accessed.
• Additional hardware errors appear after the reset.

A technician can replace internal components safely and verify there is no ink damage inside the printer.

Frequently Asked Questions

Is Brother Printer Error 46 dangerous?

No. It is a protective maintenance warning designed to prevent waste ink from overflowing inside the printer.

Can I continue printing after Error 46 appears?

No. Most Brother printers disable printing until the purge counter is reset and the maintenance issue is resolved.

Does resetting Error 46 permanently fix the problem?

Not always. If the waste ink absorber is physically full, replacing it is the proper long-term solution.

Can Error 46 damage my printer?

Ignoring the condition and resetting the counter repeatedly without replacing saturated absorber pads may eventually cause internal ink leakage.

How long does it take to repair the Brother printer error 46?

A purge counter reset usually takes only a few minutes. Replacing the waste ink absorber typically takes longer, depending on the printer model and disassembly required.

Conclusion

Brother Printer Error 46 is a maintenance alert that indicates the printer’s waste ink management system requires attention. In many cases, resetting the purge counter restores functionality, but if the waste ink absorber has reached its capacity, replacing it is the safest and most reliable solution. By following proper maintenance practices and avoiding unnecessary cleaning cycles, you can reduce the likelihood of seeing Error 46 again and keep your Brother printer operating efficiently for years to come.
