Drum light is bleeping. changed the toner, still bleeping

tell me the model please
TOSHIBA E STUDIO...............??

This machine has a separate drum and toner cartridge. Replacing the toner does not reset the drum light. Double check that the light on is, in fact, the drum light, and if it is, replace the drum unit. This should resolve your problem.
In order to replace the drum unit, do this: 1) With the printer on and the drum light blinking, open the front cover. 2) Press and hold the Go button for about 4 seconds until all the LEDs light up. Once all LEDs light up, release the Go button. 3) Pull the print assembly out of the machine. 4) Push down the green lock lever to take the toner cartridge out of the drum unit. 5) Put the toner cartridge into the new drum unit. 6) Reinsert the print assembly into the machine. 7) Close the front cover and verify that the lights turn off.
It is theoretically possible that you could reset the counter without actually changing the drum by simply skipping steps 3-6 above, but I have never tried it before and Brother may be checking a chip on the drum unit to verify that it is, in fact, a new drum unit. If they are, you will have to actually replace the unit to make the light go off. I would strongly recommend against resetting the counter without actually changing the drum though, as your print quality will degrade and the machine may start to dump toner into the inside creating a rather large mess and a hefty repair bill.

-open front cover
-press 'Option' button
-then key *00 on the keypad
-This resets the device so it knows it has had a new cartridge.

I hope it helps

If this model comes with the drum separately of the cartridge, only replace the cartridge. There's no need to change it every time. until prints start to get lines or dots. Don't expose the drum to light too much.

Hi, it sounds like you need to change the drum. If you are using the High Yield TN660 toner is your printer, then the drum needs changing every 3-4 toners. If using the low yield TN6300 toner then your drum needs to be replaced every 6-7 toners. Hope this helps

1. Open the front cover.
2. Locate the control panel button under the LED lights on the left side.
3. Press the control panel button until all lights are lit, then release it.
   The Drum counter is now reset.

On older models

1. Open the front cover.
2. Remove the drum and toner
3. Press the Go buttom button until all lights are lit, (they come on one at a time) then release it.
   The Drum counter is now reset.

f the Drum LED is still lit after replacing the drum unit, the Drum counter may not be reset.
Reset the Drum counter as follows:

1. Open the front cover.
2. Locate the control panel button under the LED lights on the left side.
3. Press the control panel button until all lights are lit, then release it.
   The Drum counter is now reset.

Alarm and Data lights on together is from low toner. If shaking of the toner cartridge is not helping, change the toner.
Drum light is usually on because of the print counter. If the print quality goes really bad, change the drum and reset the counter by holding the front button wile the front cover is open till all lights come on. Release the button and close the cover.
If just Data light is on, check the print ques, some jobs might got stuck there.

I just had the same problem and fixed it. Hold down the blue "go" and red "job cancel" buttons at the same time for a few seconds. The printer churns into action and the green status light goes on. I was able then to print.

Reset the drum counter by opening the front panel, then hold down the power button for about 5seconds until ALL the leds are on. Then realease the button and close the front panel. Your coutner will be resetted.
