Everything prints red

Check to see it the toner cartridg is fully seated. Also the is usually a tab or strip that has to be removed. Check the instructions.

Hello

Once you have the correct Brother Toner for your printer model, power your printer OFF and open the cartridge box.

Next, you need to open the top cover of the printer. You should do this carefully to prevent damage to the interior or exterior of the printer.

Once the printer top cover is removed, you want to extract the empty Brother Toner cartridge from the printer by pulling upward and away from the machine. You should be able to do this without a great amount of force.

After you've taken the Brother Toner cartridge from the printer, you want to prepare the new cartridge for insertion. To do this, you need to remove it from the plastic bag it is contained in. Next, you need to remove the rip strip from the cartridge. The rip strip is attached to a plastic film strip. Removing the rip strip is important because if you don't your printer will only produce blank sheets. Take care when ripping the strip off, as you may get Brother Toner on your clothes which can stain. If you end up spilling toner on yourself you can wash it off with cold water.

Next, you want to place the new cartridge in the printer the same way the old Brother Toner cartridge came out. There will most likely be arrows on the package to guide you in the placement that will help you make sure you're putting it in correctly. Much like removing the used Brother Toner cartridge, it should slide in with minimal force. If it doesn't slide in easily you should make sure that the Brother Toner cartridge is the correct cartridge for your model printer and then make sure that it is aligned correctly.

Once you have the cartridge in the printer properly, put the printer lid back on.

Now you are going to print a few test pages to make sure that everything is working the way it should. If the printouts look good: You are done. Package the old toner cartridge in the box the new toner came in and recycle it. If the printouts look bad: Sometimes cartridges can be defective. If there were problems with your test pages, you may need to try the process again with another toner cartridge.

The drum is the part of the unit that actually does the transfer of the toner onto the paper. Each toner cartridge does about 2,000 pages and the drum needs to be replaced with the ~6th toner cartridge change (varies with use). Order part DR-250 from Brother or any office supply place that would carry the part.

To replace (wait until print quality decreases or it reads change drum now and stops working). Turn off the unit and let it cool. Close the document tray and the extension and open the top cover. Remove the drum carefully and place it where the toner will not spill. Remove the toner cartridge (if it is still good) and set it aside to put in the new drum.
Wrap the old cartridge up and dispose of properly (not in the domestic trash). Keep the new drum out of the light (keep it sealed until needed) as much as possible. Insert the toner cartridge in the new drum. Then insert the unit into the Fax machine. (Hold by the handles) Close the top cover and the starter sheet should be ejected by the machine.

I hope this helps.

Replacing the print cartridge

1. Open the print cartridge door, and remove the old print cartridge. CAUTION: To prevent damage to the print cartridge, minimize its exposure to direct light by covering it with a sheet of paper. Figure 1: Removing the print cartridge
2. Remove the new print cartridge from the packaging. CAUTION: To prevent damage to the print cartridge, hold the print cartridge at each end.
3. Pull the tab until all the tape is removed from the cartridge. Put the tab in the print cartridge box to return for recycling. Figure 2: Removing the sealing tape
4. Gently rock the toner cartridge from front to back to distribute the toner evenly inside the cartridge. Figure 3: Shaking the print cartridge
5. Insert the print cartridge in the device and close the print cartridge door. Figure 4: Inserting the print cartridge CAUTION: If toner gets on your clothing, wipe it off with a dry cloth and wash the clothing in cold water. Hot water sets toner into the fabric.

NOTE: When toner is low, faded or light areas appear on the printed page. You might be able to temporarily improve print quality by redistributing the toner. To redistribute the toner, remove the cartridge from the device and gently rock it from front to back.

One solution is to make sure you have removed the orange plastic strip from the toner. The cartridges are sealed with a plastic strip when shipped and it needs to be removed from the toner side before installing.

This is how to Install or replace the Toner Cartridge.

Install or replace the toner cartridge while the printer is on (if the power is not on, the cartridge carrier does not rotate).

1. After confirming the Insert Yellow Toner(Y) message, open the front door.

2. Hold the tape on the protective cover and pull it forward to remove the cover from each cartridge slot.


NOTE: You need to remove the protective cover only the first time that you install the toner.
NOTE: Dispose of the protective cover after you remove it.
NOTE: The protective cover is attached to each toner cartridge mount.

3. Make sure the color of the toner cartridge matches the slot on the toner cartridge carrier. The order is Y, M, C, K. Gently shake the cartridge to distribute the toner evenly.

4. Lift the tab up 90 degrees and pull the toner seal straight off, keeping it parallel with the toner cartridge.

5. To insert the toner cartridges, align the arrows on the cartridge with the corresponding arrows on the printer. Guide the cartridge in until it snaps into place and then push down the handhold to lock the cartridge in place.

6. Close the front door.


NOTE: Make sure the toner cartridge is installed correctly. Otherwise, the front door cannot close firmly.

7. The toner cartridge carrier rotates to the next empty slot. When the color of the newly inserted cartridge appears on the display, followed by the Insert message, insert the next toner cartridge.

8. Repeat steps 1 through 7 when inserting the remaining cartridges.

the chip is faulty on the black cartridge, change the black and it'll work, alternately you can out it diagnostic made and run without the cartridges being monitored

This may be a help. I had a similar problem with an ML-2850 which fresh out of the box refused to print, not even a test page, green light followed by red and the smart panel showed that the printer thought that there was no toner in it.
After struggling with it for an hour I hit upon the following.
Turn off the printer.
Take out the toner cartridge.
In the hole where the toner came from there's a gear on the left hand side which is sort of diagonal mesh to match the underside of the toner cartridge. Rock it back and forth a bit and then stick the cartridge back in.
My guess is, if you're unlucky when you install a new cartridge you could have a situation where the gear is in exactly the wrong position, tooth to tooth with the underside of the toner so this gear doesn't mesh properly, the cartridge doesn't seat properly, which then shows the printer as having no toner in it. Waggling the gear just changes the position slightly and then voila. A bit like rocking a car back and forth in gear to free a stuck starter motor.

it is printing with this blinking or not?
