SOURCE: Brother Laser HL-5240 has a status light and toner

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.

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.

Try this..
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.
