Drum error I have a HL-4040CN and it wont print for a drum error. it says to slide green tab on each color and how ? and where.

replace the drum unit

1. power down the printer.
2. remove all color cartridges from their slots.
3. inside the color slot, you will see a green slide that will not move until you pick up the plastic cover (it is the full length of the cartridge holder).
4. rotate the plastic cover forward.
5. slide the green slide 3 or 4 times. (DO NOT TOUCH SMALL WIRES!)
6. return slide to original position.
7. snap the plastic cover back in place
8. return each color cartridge to it's slot.
9. replace color cartridge holder back to printer.
10. close all covers
11. turn printer back on.

If you still get the "move green slide" error, just repeat these steps

This took me about 10 minutes for the process, after understanding what the "green slide" meant. -->

The green tab slides from left to right.
This cleans the croner wire. These wire also have a tedancy to break every often.
The drum unit will need to be replaced

I just post a ->LINK because the fix is long,to clean the drums.

maybe there is trouble with ink drum, try cek it, for more info go to provider home page, download the manual book

Open up the printer and slide the green tabs to clean the drum chargers

The DRUM life is near to end . Replace the DRUM to solve the problem.

this printer has 6 Drum, check all, and look internal counters is available on the menu they are down counters. If Continues go the Brother Repair Center, for repair.

I had this same problem when printing photos. Go into printing preferences, then the Advanced tab up top.....make sure "Color Mode" has NONE selected. That lets the program you are using do the color management.

Hope that helps!!

The green tabs that you have to slide are under the color cartridges, so remove the three color cartridges and you will see three green tabs, to slide the tab across the wire you have to first open the translucent plastic wire cover, then slide the green tab across the wires and return it to it's original position, close the wire covers, replace the color cartridges, and reassemble the printer. All the Best
