I have fix toner but toner error can't gone and pirinter is not working?

black toner supply trouble, try a different toner cart, remember to shake the cart before installing. power the machine on and off, if the code is gone then it was the cart if it doesn't clear your service tech needs to see the machine.

if replaced the cartridge ,The problem is something else.but u refilling the toner, maybe the chip set on the cartridge is gone.

I would highly suspect a defective toner. What happens if you put the old toner back in - - do you get the same error? If you don't, then replace the toner. If you continue to get a lsu error, then your Laser Unit has a toner spill on the glass, or has gone bad and will need replaced.

hello,
their is small fuse in your toner cartridge.you have to replace it . it is also damage.

9-357 system fault

Hi ...

LSU stands for Laser Scanner Unit ... you normally get 2 different kind of errors with LSU ...
LSU Hsync or LSU Motor Error ...
If you get this error, it means that the Laser Scanner Unit has gone bad and the only way to get it fixed is to get the printer repaired ...

Cheers ....

try and take the toner bottle out and turn machine on and than put the bottle back.it;s bottle sensor problem.good lock

with machine on, open front cover, press the "options" button, you should see "replace drum?" press the "start" key then 1 then 0. display should show accepted for a couple of secs. then show cover open. close front cover and message should be gone. if not, you will have to contact Brother.

hth,

error message??

There are two screws on the drum unit. They are on the left hand side and one on the right hand side. Remove the screw from one side and take off plastic small side cover. Dump the waste toner. Do the same for the other side and then put it back together. Turn machine off then on and the error code should be gone......
