PROBLEM BROTHER 2040 PRINTER

If all the LED's are flashing and continue to flash for more than 10 minutes with the unit powered up, it needs to be serviced or replaced. (That is toner, drum, paper and the Ready light all blinking -> critical error found in self-test.) If the Ready light is off and the rest of the lights are steady, the toner is out, the corona wire needs cleaning and the paper tray either is empty or not picking up the paper.

I hope this helps.

How to Change a Toner Cart in a Brother HL 2040

The Brother HL 2040 laser printer has a toner cartridge that supplies toner to the drum assembly so that the printer can print properly. When the LED on the front of the printer indicates you are low on toner, you will need to replace the toner cartridge to maintain good print quality. Fortunately, the toner cartridge can be replaced without any special tools.

Instructions
Things You'll Need:

* Replacement toner cartridge (part number TN350 or TN360)
* Paper towel or scrap paper



Grasp the front cover of the printer and pull it toward you to open the toner door. Reach into the printer and grab the combined toner cartridge/drum assembly. Lift up slightly and pull it out of the front of the printer.

Place the cartridge and drum on a paper towel, spare sheet of paper, rag or other surface that can get dirty. Loose toner particles may spill from the cartridge.

Press the blue locking lever on the cartridge/drum unit to unlock the toner cartridge from the drum. Lift the toner cartridge up and away from the drum unit. Dispose of the old toner cartridge in accordance with your local regulations. Seal it in a plastic bag to keep loose toner from spilling.



Gently shake your new toner cartridge back and forth a few times to distribute the toner evenly across the width of the cartridge. Remove the plastic protective cover from the bottom of the cartridge.


Place the new toner cartridge onto the drum unit and press it down gently until it locks into place. The blue locking lever will automatically click into place. Verify that the toner cartridge is securely connected to the drum.


Locate the corona wire cleaner tab at the front of the drum unit. Slide it back and forth several times to improve the print quality of the drum. Set the tab back in the home position when finished.


Slide the combined toner cartridge/drum unit back into the printer and close the front cover.


Hope it helps...

Hello ,

This problem is a common issue and easily fixed.
When putting in a new toner cartridge, the printer usually automatically resets the toner count.
In a situation like this, the printer did not automatically do the reset and so we must manually reset the printer.

To manually reset the printer, first, remove the toner from the printer and separate it from the drum unit.

With the toner cartridge in hand and the brother writing facing you, look to the left side of the cartridge. You should see an arc shaped opening with a white tab in it.

The tab is set at the right position and must be pushed back to the left side of the opening.
To push the tab back, you must turn the grey gear attached to the front roller upwards as you push the tab.

Once the tab has been placed to the left position, the printer will accept it as a new toner cartridge.

Thanks,

Pat

Sounds like the toner cart. has toner packed at one end and possibly the drum cartridge is dirty. Remove both from the printer, separate the 2 and vacuum the drum cart. - them blow it clean. Run the drum wire cleaner (purple/blue tab on front edge of drum cart.) back & forth a number of times. Blow out the inside of the printer to get out toner dust. Reinstall toner back into drum cart, then hold GO/Control button down until all lights are on, let go, reinstall toner&drum back into printer, close door. Power down - then back on. That should do it. Worst case, you'll have to replace the drum unit.

Front panel of printer (manual paper feed is in the middle of this panel) has tabs on the right & left and will fold out and down. The toner/drum is right inside. there's an opening in the middle to grab it and pull straight out. The toner will separate from the drum unit by holding a small purple/blue tab on the left side down, and then lift up and out. Reverse this when putting everything back. remember to shake the toner right-left to loosen the toner before putting back in the unit. To reset the printer, and with the front door still open, hold the GO-Control button down until all lights are on, then let go, close up front door. Power off & back on and you should be set.

Remove toner/drum unit, remove toner by itself...remember to shake the toner right-left to loosen the toner before putting back in the unit. To reset the printer before you replace the toner/drum, and with the front door still open, hold the GO-Control button down until all lights are on, then let go, reinstall the toner/drum, & close up front door. Power off & back on and you should be set.

Please try to hold on the "start" buttom for 1 min until the 4 lights on.
I hope this works

I have 'reused' the same drum three times and still prints like a charm.
Open the toner door and pull out the toner/drum assembly. Take the toner off the drum tray. Use a alcohol pad or lint free cloth and wipe the mauve coloured drum to remove the excess lint and toner collected on the drum. Rotate the drum with the white gear and keep cleaning until the whole drum is done.
Put the toner back in the drum tray. Clean the corona wire by sliding the blue tab back and forth 3 or 4 times. Put the toner/drum back into the printer and close the door.
After the printer does the self test the drum light will cone on again so then you need to reset the counters.
Open the door again
Hold the GO button until all 4 lights are lit up
Release the GO button
Close the door
Printer will self test and should extinguish all the trouble lights.

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.

Did you check the back to see if there is a paper stuck. If nothing is stuck then shut it off and restart it. I have lots of luck with this printer. I work at 2 schools and have 62 of these to keep in working order. I have only had 1 that had to be sent in for repairs.
