Brother Printer LED Indications [Meaning]
The lights flashing on your Brother Printer are technically known as LEDs (Light Emitting Diodes). The two main LEDs are the Error LED which is orange in color and the Ready LED which is green in color.
We will be looking at Brother Printer LED indications as well as their meanings below:
1. Turned Off Error LED and Dimmed Ready LED Meaning
i. Sleep
Your Brother printer has gone into Sleep Mode. In this mode, data can still be received; hence, when you send a document for printing, the Brother printer will come on and begin printing.
ii. Deep Sleep
In this case, the printer has gone into Deep Sleep Mode. This mode allows your Brother machine to use less power than when in Sleep Mode. In this mode, data can still be received; hence, when you send a document for printing, the Brother printer will come on and begin printing.
2. Turned Off Error LED and Turned On Ready LED Meaning
i. Ready
This means that the printer is ready to start printing. Therefore, you can print any document sent.
ii. Printing
When your Brother Printer has the above-LED indications, it means it is printing.
3. Turned off Error LED and 1 second or 1.5 seconds Interval Blinking Ready LED Meaning
i. Please Wait
If your Brother Printer ready light is flashing in this manner, then it could mean that your printer is getting warmed up to start working.
ii. Cooling Down
This LED indication could also mean that the Brother Printer has become very hot. Hence, the printer will pause all print jobs and enter Cooling Down Mode. You don’t have to do anything but wait until it goes back to Ready Mode.
iii. Receiving Data
Your printer is receiving data sent from your computer or the printer memory could be processing data.
iv. Data Remaining
Your Brother Printer might have this LED indication because the memory of your printer still has some print data remaining.
If the light keeps blinking for long without any printing, you can stop the blinking by pressing the power button of your Brother Printer. This action will cause the printer to print the data that is left in its memory.
4. 1.5 seconds Interval Blinking Error LED and Turned on Ready LED Meaning
i. The Toner is Low
The Brother Printer toner light flashing, in this case, indicates that your toner cartridge needs replacement very soon. Hence, you need to purchase a toner cartridge which you have to keep ready for replacement immediately your printer asks that you “Replace Toner”.
Hack: If your print jobs are becoming faint, it means the toner in the cartridge isn’t evenly spread. Simply take out the toner cartridge and drum unit assembly and shake it from one side to the other. Ensure that the assembly remains level while you do this.
ii. Replace the Toner (Continue Mode)
If the toner light is flashing on Brother Printer, then it could also indicate that the toner needs to be replaced. You can ignore it and keep printing, but the printing will stop once you are completely out of toner which your Brother Printer will indicate as “Toner Ended”.
Brother Printer flashing yellow light indicates low toner or “replace toner” on some Brother Printer models. On the other hand, Brother laser printer red light flashing indicates low toner or “replace toner” on other models. Hence, the red light flashing issue on Brother 1110 and Brother 1210w printers will be fixed with the solutions in this section.
5. 1.5 seconds Interval Blinking Error LED and Turned off Ready LED Meaning
i. Replace the Toner (Stop Mode)
Brother Printer error light flashing, in this case, indicates that the printer’s toner needs to be replaced. The printer will not work if this is not done.
Therefore, you need to replace your Brother Printer’s toner cartridge to stop the error light flashing on Brother Printer. Read this article to find out how to do so.
ii. Toner Ended
If your Brother laser printer error light is flashing, then it might be because the toner in the cartridge is completely exhausted. Once this happens, you will get the “Toner Ended” message.
Therefore, you need to replace your Brother Printer’s toner cartridge to fix this.
iii. No Toner
If there is no toner or the cartridge wasn’t installed properly into the printer, this might cause the Error LED to keep blinking.
Therefore, you need to properly install your toner cartridge as well as the drum unit.
Brother Printer hl 1210w flashing light error could be caused by these issues we just mentioned.
6. Error LED Blinks 4 times before Turning off for just 1 second and Turned off Ready LED Meaning
i. Cartridge Error
If the toner cartridge and the drum unit assembly are not properly installed, it could lead to this error.
To fix this, you need to reinstall both components properly into your Brother Printer.

Why Is My Brother Printer Paper Light Flashing? [Detailed Guide]
Your Brother Printer paper light keeps flashing because of the reasons below:
i. The Manual Feed Slot Doesn’t Have Any Paper
If there is no paper in the manual feed slot, the paper light will start to flash. This isn’t a serious issue but an indication that the printer has run out of paper.
Hence, to fix this issue, simply put paper into the manual feed slot. Ensure that you align the paper properly in the slot so that it doesn’t get jammed while printing.
Furthermore, make use of the correct paper type and size. If you don’t, the paper light on your Brother Printer might continue flashing because of this mistake.
ii. There is a Paper Jam
Once there is a paper jam in any part of your printer, the device will stop printing automatically and the paper light will begin to flash. Sometimes the paper jam prevents the machine from printing at all while in some other cases, the printer stops working to prevent further damage to the internal components.
If this is the cause of the flashing paper light on your Brother Printer, then you can fix the issue by getting rid of any paper jam in your Brother Printer. We shared an article link earlier on how you can do that.
iii. The Front or Back Cover of Your Printer Is Open
The open front or back cover of your Brother Printer sends a signal to your printer that the user is still working on the device. Hence, it won’t perform any printing function until the covers are closed.
Therefore, if the paper light on your Brother Printer is flashing, you need to check the front and back covers if they are properly closed. If they are not, ensure that you close them properly. When you do this, the flashing light on the printer should stop.
v. The Drum Unit Has Dust on It
Dust on your drum unit can cause your Brother Printer paper light to start flashing. The printer does this to protect the quality of the print job because a dirty drum unit can affect the print quality by staining it.
Hence, to get your printer working again, you need to take the drum unit out of your printer and then get rid of the dust on it.
vi. No Drum Is Installed
The drum unit is necessary for printing. Therefore, the absence of this unit within your printer is bound to trigger an error. Therefore, if for any reason you didn’t install the drum unit, ensure that you do that. When you do, your printer should be back in business.

Brother Label Printer Flashing Green Light [Quick Guide]
The flashing green light on your Brother Label Printer can be caused by the following:
i. The label printer is unable to feed the label out and not able to detect the black box that is on the backing tape’s right side.
There are special markings on Brother DK labels/tape rolls that allow the Brother Label printer to discover the loaded label/tape roll. When a non-genuine/non-Brother label/tape roll is used, the printer will not recognize it because of the absence of these special markings.
ii. The size of the DK label/tape roll in your Brother is not matching the software selected size.
For the machine to work, the roll size must be set according to that which is selected on the software. Once the sizes are not the same, the green light will start flashing.
You can find the DK label/tape roll’s size by the spool’s left side to help you match it with that on the software.
iii. A communication issue exists between your Brother Label printer and your computer.
This communication error could come in form of a bad cable or wireless connection. In other words, if your printer is not receiving data that is sent from the computer, it can cause the flashing green light on your Brother Label printer.
How to Fix Brother Label Printer Flashing Green Light
The following steps will guide you on how to fix the problem of your Brother Label printer flashing green light:
i. Check for an error message being displayed on your computer screen. If you find one, it could tell you why the Brother printer is flashing green light.
ii. Turn off your printer and take out the DK label/tape roll from your printer.
- Then check the printer’s compartment right side for the 5 sensors that detect the DK roll that is installed. You can identify them by looking for small black posts that are just 1/8 inches high that protrude from the inside of your Brother Label printer.
- Confirm that the sensors aren’t damaged or stuck facing down.
- Push down each sensor switches to make them spring and face up. Once you do this, all 5 sensors will have equal heights. In case they don’t or don’t spring up, then the switch is bad. You’ll need to take the machine for repair.
iii. Reinstall the DK label/tape roll.
- Carefully insert the DK label/tape roll spook along with the printer’s spool guide. You can find the spool guide on the printer’s compartment right side.
- Make sure that the labels/tape’s strip isn’t stuck under the right positioned spool. The spool’s bottom must contact the switches at the compartment’s right side directly.
- Make sure that the DK label/tape roll sets securely in the printer’s compartment.
- Turn the DK label/tape roll on the exact spool that is near the machine’s back. Ensure that it rotates freely.
- After that, take the roll’s end and thread it into the right slot. Do this until the roll’s edge is visible at the printer’s front.
- Then push the release lever down before closing the cover.
iv. Press the button labeled “FEED”. When you do this, the light should be green.
If the printer feeds an installed Die-cut label/tape roll backward once your press “FEED”, then it is okay provided the LED is green but not flashing.
However, if it is flashing green light, then you need to turn your Brother Label printer off and then reinstall the roll again.
The spool’s right side tab should be able to slide freely between the right side guides’ opening. Make sure the tape backing faces up; you can identify the tape backing by the Brother logo on it. The label/tape should face down.
Then thread the roll as explained earlier. If you can’t thread it till it gets to the printer’s front, then a label might be jammed inside. You can remove it by using a thick card to push out the jam from the roll compartment to your Brother Label printer’s front area.
If after doing this the green light keeps flashing after “FEED” has been pressed, then you need to take the machine for service and repair.
v. To confirm that you are using the right label size, open the P-touch Editor Software on your computer. Then click the button or icon for “Check Media” and try to print a label.
vi. If the green light is flashing or a communication error message is displayed as you try printing a label, then do the following:
- Make sure that the DK label/tape roll size installed into your label printer matches that selected in the software.
- Ensure that your USB cable’s connection is properly secured.
- Avoid connecting your USB cable to a hub; instead, connect it to your computer directly.
- Connect the USB to a different USB port on your computer.
- Try using a different USB cable.
- Uninstall and reinstall your printer driver.
- Connect the printer to a different computer.
If the issue is not resolved after all of the above, then you need to take your printer for service. Simply find a Brother Authorized Service Center that will help you with either replacement if you are within your warranty or a repair if you are out of your warranty. For the latter, you will have to pay for repairs.
