I argued on the phone with a BROTHER REP. that he should give the codes and directions to reset the machine, he refused time and time again, saying that this means physical damage to the machine an re-setting it is impossible to help, but i insisted, and it did fix the problem and the error went away.
here is what you should do, unplug for 10 sec. press and hold on the menu key while you plug it back in untill you see the screen "parameter init" press 99 and wait, this is what i did and it fixed the problem !!

This is very easy to solve. Remove the drum and toner cartridge. Look into the machine where they sat. Now look up and you will see (a little aukward but its there) a glass plate the width of an A4 sheet of paper. Run your finger accross it. Look at your finger and will probably be dirty. This is the window the laser beam passes thru to hit the drum. When its dirty it does not allow enough ;light to the drum hence a weak beam and light printing.
simples?

You have to open the front door and then press options, should see Replace Drum? just answer yes.

To remove the fuser - remove the tray at the bottom and the back tray (4 screws, 2 either side) lift out the phone line box on the right (looking from the back - 2 screws) and swing it out of the way (careful as cable isn't too long) 2 screws either side of the fuser (long black object at the bottom) unplug the halogen lamp (white plug on left) and small 5 wire plug on right, and lift out fuser unit.

Hi,

With the front cover open, press clear/back., press 1 and when the LCD shows accepted, close the front cover and you should be all set.

I hope this helps you..

Hi,A6 error means the CIS unit is defective and needs to be replaced. Unfortunately this can sometimes cost more to replace then the machine itselfThank you Regards,Suhail

All you should have to do is: -replace the old drum with the new replacement. -with the front door open press the Clear/Back button -press the number 1 button and when ?accepted? appears on the LCD close the front cover. That should do it. Let us know if you have any other questions and please don?t forget to rate this post.

For the error code "7a" to be fixed permanently, you need to ensure that the main PCB is fine and is working in good condition.
If the error code is caused due to malfunctioning of the main motor, then you need to check the whole setup by connecting it with another motor.
In this case, make sure that there is no mechanical load present on the main board.
While fixing this error code, you will notice that the motor runs slowly initially and then picks up the speed later.

press the 3 and 9 button at the same time in ready mode.

then the reset menu will appear, press the up or down arrow until you get to drum.

press ok,
and select 1 to reset or 2 to exit.
it will return the ready state and your done.

No solution, but I have the same problem. THe printer starts up fine, I hear no grinding noises or other "funny" nioses, and then displays no error message... UNTIL I ask it to print. Then I get a message that says, "Pls (please) Open Cover". I open the cover and it says "Please Close Cover". I close the cover and it says, "Please Open Cover"and this happens forever! Does anyone have any ideas? Can anyone help me?Stefan

heya!
this stands for brother mfc-8440 as in the title.
you need to reset the "drum counter" of your printer..
to do so try one of those

Brother Laser Printers:

After replacing the drum unit, keep the front cover open (make sure the power is on). Press and hold the "GO" button until all four LED's are lit. Once the four LED's light up, close the front cover. Make sure the drum LED is off. The counter is reset!

Brother Fax Machines:

Open the front cover. Press the CLEAR/BACK button. Press 1, when the display shows accepted.
