    Thanks for coming back so quickly.

    The cartridge is the original & we refilled it with toner.

    It has 2 screws holding the side on that covers the gears there is a very short plastic arm connected to a gear this is in the full back position & locks in to place.

    I have tried it both forward & backward.

    still no joy I have ordered a new cartridge but it wont arrive untill Tuesday.

    I use this printer at work & need it for today & monday.


    If you can suggest anything else for a quick get you out of trouble thing to do.

This works on several different Brother Printers to get rid of toner/drum empty errors:

1. Open the front cover and leave open while completing the following steps.
2. Turn the printer off.
3. Hold the 'go' button while turning the printer on. All panel lights should be on.
4. Release the 'go' button.
5. Press the 'go' button 2 times.
6. Pause.
7. Press the 'go' button 5 times.
8. The toner light should be off.
9. The paper light should be on or flashing [doesn't happen on all].
10. Close cover. The ready light should be the only light on.

When a brand new toner is inserted it has a switch that is activated when new cart is installed.


Machine has two toner light errors blinking is toner low, full on is toner out all stop,


 I guess yours has not reconised new cart, was it new out of a sealed box?


If so then it failed to reset upon install


You can pull apart reset lever on left front of cartridge and reset to original position if you want to get just a little tecnical


One sctew carefull gears fall off ,white lever needs to be fully to rear of slot to emulate new cart status..


If brand new cart return to supplier as faulty.


If you just refilled it, go buy a real one to prolong life of your product

    When it is in correct position it hits a switch on inside left that resets counter, after insertion the switch should return to front position.


    I reset when needed and I just losen front screw and push lever back, maybe true home posion is not fully back but at 9 o'clock


    Cartridge also has a visial switch that looks threw a little window that runs entire lenght of cart but if you have refilled it then that should not be your issue.


    I'm sure it is the switch,


     I dont recomment refilling have seen it cause oh so many issues.

Toner light comes on and it won't print

WHen the toner light comes on this means you need to replace the toner cartridge because its empty. The toner its the powder that is used to put on the paper, you will no longer be able to print until you replace it with a new one.

I have a Brother 5240 printer. The toner light

Try this... it reads the level of the toner and can become faulty. This clears it.
1: Turn off power and remove toner/drum
2: Tape the little spring loaded lever just inside the printer on the upper left hand side in the *DOWN* position! Do not replace drum yet and...
3: Turn power on to printer and let it cycle. Status/Toner lights will come on as usual.
4: Turn off printer, remove tape from lever, replace drum and turn back on.

Brother Laser HL-5240 has a status light and toner light. Fuser was replaced but no help.

that error usually indicates that the toner has reached its end of life
or the drum is not properly installed.

i had one person who put the toner in but threw the drum cartridge away.

Toner light won't go away.

Ok, now I can help you.

You have a fatel error in your printer. This is unfortunate, but I call them as I see them. The fuser unit has failed and will require replacement. A simple enough task for a technician, but it might take you a little longer. If you hunt around on the internet you should be able to find a fuser unit from a local brother service agent, if they will sell it to you. Otherwise you might be able to look up brother spare parts and you should find something.

Please remember to rate my assistance.

Kindest regards

My Brother HL 5240 has Status toner, drum and paper lights on, I bought it on 4/30/08, new toner, plenty of paper, it showed on computer: printer is off line, but it was connected with computer. Really...

The drum light will flash on my brother HL-5240 Laser Printer when printing but it continues to print just fine. Does this mean the drum needs to be replaced?
