SOURCE: Problem with my printer Brother MFC-240C "Print unable 4F"

Access the internal maintenance mode by pressing the Menu/Set button, then press * 2 8 6 4 within 2 seconds. This should put you in the maintenance mode menu. Enter 80, then scroll down with the arrow down (round) key. You'll find an entry listed as purge count. If number is over 6000, enter 2 7 8 3.

This will reset the purge count value. Then the printer will restart,
try this step by step.without missing any thing. thanks

SOURCE: MFC-9440 CN Laser Printer is producing vertical color line streak

Colored vertical streaks - looks like a transfer belt problem, and it's not user fixable. You may need a new belt unit - you can find it for around US$ 80-120, but you may want to have a technician inspect the unit first, since it could arguably be the drum instead, and you don't want to fork around US$ 100 and replace the wrong part.
You can try showing a printer sample at a print shop; by looking at the streaks it is possible to diagnose drum, fuser or belt problems.
Here you find a much more detailed page, for another printer model, but the issues are mainly the same for most color printers:

Change language mfc J4510DW

Nope, language does not change that easily.
I've changed my printers language, but it's a lot of work.

Here are the steps needed:

1. You need to download the Filedl32.exe (brother's tool for uploading firmware to the printer) and the brothers Maintenance mode drivers. These can be found here:

2. You need to enter maintenance mode on the printer. To do this, follow the steps below:
  • Press and hold the Home Icon on the printer's screen
  • After you see the firmware info, press and hold the last box (which is empty) until a menu appears
  • Within 3 seconds type the following *,2,8,6,4 (without commas)
  • If you did everything correct you should be in Maintenance mode
A video showing the above can be found here:

3. Now you need to change language. To do this, type 74 and press set mono. In the language menu change the language from 0003 (Germany) to 0001 (USA) then press set mono again. Now the printer will set the language to English and will prompt you with Please DL Rom

4. With the printer in maintenance mode, connect it via USB to your PC in which you already have installed the Maintenance drivers. The PC should recognise the brother printer as Maintenance Brother Printer

5. Now comes the tricky part, you need to get your firmware file, which is not easy. My solution was based on this post:

My issue though was finding the correct values to post to Brother, as my printer was differently. Unfortunately using SNMP didn't help as none of the parameters did show up on snmpwalk.
So I did another trick, since I also have a Mac. I did use a proxy (Charles) and run the firmware update jar file. Now initially I failed, since Brother is using SSL, which made it impossible to get the post data, but I was able to change in the updater tool the BrUpdSys.xml file and change the file URL (FileGet XML node) to something random,, which allowed me to get finally the post XML data.

Using those and posting those with CURL I finally got my firmware, which I installed.

The firmware request file of mine look like this:


So as you can see it's quite different than the one on the blog post.
Anyway, after posting this I got the firmware URL for the english firmware which is this:

Note, the above is for the model MFC-J4510DW ONLY. so don't use it in another model.

Note 2: If you want to change the language to something else (not English), you'll need to change the 0003 to 000X in the printer's maintenance mode and also in the <SPEC> XML node above.

You can see the country list codes in this pdf:

If you scroll to 1.4.26 EEPROM Customizing (Function code 74)

6. After you have the file, just open the Filedg32.exe, locate the Brother Maintenace USB printer icon and drop it there. It will upload the firmware to the printer and the printer will reboot. After reboot your printer should have finally an English menu!

Good Luck and remember you are responsible for what you do.
To help you I have also uploaded my firmware file on dropbox, so you can use that one and skip the curl steps, if you like!

My firmware file:
My request.xml file:

I've also uploaded the driver and filedg32.exe files in case you can't find them anymore in the website I did provide:

Maintenance mode in brother mfc 5910 dw

Robbin, your anwer is wrong, those kind of codes are usually not provided in the owners manual. I had a bad inyector obstruction problem on another Brother and the support provided me a maintenance code to access a hidden menu with "heavy" cleaning options that don't appear in the manual.

Try running a purge count through the maintenance menu. You can enter maintenance mode by pressing: Menu> * 2 8 6 4 Press 8 0 Scroll down to purge count value. You should get there after pressing the down key 24 times. Press 2 7 8 3 to reset the purge count. The printer will then restart. Then try printing again.
