To send a fax, you will have to configure the settings. here are the steps you can follow;

Remote Fax Options;
You can only use one remote fax option at a time:
Fax Forwarding—OR—Paging—OR—Fax Storage—OR—PC FAX Receive—OR—Off.
You can change your selection at any time (Menu/Set, 2, 5, 1).

Setting up Fax Forwarding

When you select Fax Forward, your MFC stores the received fax in the memory. The MFC will then dial the fax number you’ve programmed and forwards the fax message.
  1. Press "Menu/Set, 2, 5, 1".
  2. Press ▲ or ▼ to select "Fax Forward". Press "Menu/Set". The LCD will ask you to enter the fax number to which faxes will be forwarded.
  3. Enter the forwarding number (up to 20 digits). Press "Menu/Set".
  4. Press ▲ or ▼ to select "Backup Print:On or Backup Print:Off". Press "Menu/Set".
If you select "Backup Print:On", the MFC will also print the fax at your MFC so you will have a copy if there is a power failure before it is forwarded.
5. Press "Stop/Exit".

Programming your pager number When Paging is selected, your MFC dials the pager number you’ve
programmed, and then dials your Personal Identification Number (PIN). This activates your pager so you will know that you have a fax
message in the memory.
1. Press Menu/Set, 2, 5, 1.
2. Press ▲ or ▼ to select Paging.
3 . Enter your pager phone number
followed by # # (up to 20 digits). Press Menu/Set.
Do not include the area code if it is the same as that of your MFC. For example, press 1 8 0 0 5 5 5 1 2 3 4 # #.
4. If your pager needs a PIN, enter the PIN, press #, press Redial/Pause, enter your fax number followed by # #. Press Menu/Set. (For example, press 1 2 3 4 5 # Redial/Pause 1 8 0 0 5 5 5
1 2 1 2 # #) —OR— If you do not need a PIN, press Redial/Pause, enter your fax number followed by # #. Press Menu/Set. (For example, press Redial/Pause 1 8 0 0 5 5 5 1 2 1 2 # #)
5. Press Stop/Exit.
■ You cannot change a Paging number or PIN remotely.
■ If you have set Paging, a backup copy of the received fax will
automatically be printed at the MFC.

Setting Fax Storage
If you select Fax Storage, your MFC stores the received fax in the
memory. You will be able to retrieve fax messages from another
location using the Remote Retrieval commands.
1 Press Menu/Set, 2, 5, 1.
2 Press ▲ or ▼ to select
Fax Storage.
Press Menu/Set.
3 Press Stop/Exit.
Setting PC Fax Receive
If you select PC Fax Receive, your MFC will temporarily store your
received fax messages in its memory, and then automatically send
the faxes to the PC. You can then use your PC to view and store
these faxes.
1 Press Menu/Set, 2, 5, 1.
2 Press ▲ or ▼ to select
PC Fax Receive.
Press Menu/Set.
3 Press ▲ or ▼ to select
Backup Print:On or
Backup Print:Off.
Press Menu/Set.
4 Press Stop/Exit.
If you have turned on Fax Storage, a backup copy will
automatically be printed at the MFC.
  • Before you can set up PC Fax Receive you must install the
MFL-Pro Suite software on your PC, make sure your PC is connected and turned on. (For details, see Using Brother PC-FAX software on page 5-1 in Software User’s Guide on
the CD-ROM.)
  • If you select Backup Print:On, the MFC will also print the fax at your MFC so you will have a copy if there is a power failure before it is sent to the PC.
■ If you get an error message and the MFC cannot print the faxes in memory, you can use this setting to transfer your faxes to your PC.
Turning off Remote Fax Options If you set the Remote Fax Options to Off and there are faxes in your MFC’s memory, the LCD will give you two options.
  • If you press 1, all unprinted faxes will be printed and erased
before the setting turns off. If a backup copy has already been
printed it will not be printed again.
  • If you press 2, the memory will not be erased and the setting will be unchanged.
Setting your Remote Access Code

The remote access code lets you access the Remote Retrieval features when you are away from your MFC. Before you use the remote access and retrieval features, you have to set up your own code. The default code is inactive code (--- ).
  1. Press Menu/Set, 2, 5, 2.
  2. Enter a three-digit code using numbers 0-9 or . Press Menu/Set. (The preset ‘ ’ cannot be changed.)
  3. Press Stop/Exit. Do not use the same code which is set in your Fax Receive Code ( 51) or Telephone Answer Code (#51). You can change your code at any time by entering a new one.
  4. If you want to make your code inactive, press Stop/Exit in Step 2 to restore the inactive setting (--- *).

I had this problem when tried to install network driver to Brother HL-L2340D (exactly InstallNetworkDriver - 3, not InstallNetworkDriver - 1). Tried it several timers, when print spooler service was running. But still got the same error.

Finally, i forgot about install wizard and installed driver manually (for my Win2008R2x64, it was DeviceManager >> Install old device >> Manual choice from list >> Show all devices >> Install from disc >> target to unzipped wizard content folder (...install/driver/gdi/32_64) >> select wanted printer model in appeared list >> continue install it.

After that, you can install this printer with standart applets of control panel (Printers > Install printer), it successfully finds printer in network and add it to list.

So, i still don`t know the reason, but have the solution.

I would guess it is the rollers. You can try to replace them. You can order them online. To find out what type you need, look on the back of the printer for the make and model.

Press the Stop Button to cancel whatever you are doing on it. Then press Copy to be able to copy.
If you are printing to it from a computer it should just automatically get to printing when it is sent information.

A9 is Brother's code "Abnormal scanning reference voltage"; try restarting the fax machine and trying again, or replace the scanner unit. (per Brother's website)

The Brother printers have a counter which will shut the printer down when the preset number of copies has been reached. You can reset the counter and it should print again. I did this 4 months ago. It bought me a little time, but my printer has begun to print a solid line down the left side of each page. I have cleaned everything that I can access to rule out smudged glass, etc. Perhaps it is just best to replace the drum or buy a new printer(much to Brother's delight and design).

I have the answer. I just fixed mine. The sensor is not really on the door. You have to remove the door by openning it all the way and carefully sliding it out ( one of the pegs holding the door is hourglass shaped. This will slide out first. The other is round. You will see a black flap that covers a red drum. Pull the flap down carefully. There will be a six inch long rod it's about 1/8 of an inch in diameter. It extends from the middle of the flap all the way to the right side. This probably popped out of place. Make sure that it is all the way to the right as this is where the sensor is. There is a little spring on the bar on the left side. This should be straight up and down. if it is not, then you need to fiddle with the bar.
The trick was that the sensor is NOT on the door, but on this inner flap. When the door closes it pushes this flap agains the drum and the little bar activates the sensor.
Please do not applaud so loud, you are ambarrazing me!!! hehehe. Good luck!.

Get the manual, and you may need the install disk too. Look carefully at the usb port on the copier so you get the correct usb cord.

leave it on for a couple minutes and turn it off for a couple minutes, and try again, if still does it, you are having a problem with the scanner not properly going to home position. it will need to be repaired.

Try putting a piece of paper in the manual feed tray which is right above the paper tray.

For thicker paper its better to put in the manual feed.
