normally you will need to let the printer know that you have preformed any maintenance on it by clearing the error count after such an error occurs and is fixed it is normally listed under general or service options on the printer menu but you may need to look through the users manual

hope this helps

"Unable to Print" error message

you need to check that no paper is jammed in the gears - even tiny little scraps can cause the machine to throw up an error message.

Unable to clean 50 error

I have a Brother MFC-440CN fax machine and I am receiving error message "unable to clean 50". Can anyone help me to fix this error problem

Problem faxing-error message

Error 388:

There is too much noise on the line for a valid connection between two fax machines to complete. The noise problem might go away over time.


Retry the fax reception at a different time when telephone line conditions have improved. Call the telephone provider if line conditions fail to improve.

Error 403:

During a V.34 transmission, the local machine is unable to connect (handshake) with the remote machine and is consequently unable to send a T30 frame. This occurs when the line is disconnected or if line conditions degrade during the session.

  • Remove any pass-through devices from the phone line, and then try the fax again.
  • Confirm that the fax/phone cable is no longer than required, and that it does not pass near unshielded electric motors such as fans, heaters, or household appliances.
  • Try to send the fax at a different time when telephone line conditions have improved.

Brother MFC-5840CN unable to scan

From Brother Customer Service email:

You can try the following reset - it will most of the settings back to the default options.

Unplug power cord to the machine.
Press and hold down Menu.
Plug power cord back in.
Let go if menu when fax/scan/copy flash.

You may see either "maintenance" or "machine error xx" on the screen.

Type stop/exit, 9, 1.
The machine should show "param init" or similar to show that the reset is being done.

It will then go back to or machine error.

Type stop/exit, 9, 9.

This should take the machine out of maintenance mode and back to normal.

If the error is still present the machine will require an engineer to resolve the issue.

"Unable To Change" message. Tried all suggested fixes none work. Can you provide any additional help beyond the standard fixes. Nothing is jammed, turning it off for even days doesn't remove the error...

press menu then start bk copy then fourtimes arrow up. what error code does the machine display?

In case you have an error 50 you have to open the printer cover and to reinsert the encoder strip which is out of position into the ph. This occurs sometimes after a serious paper jam.

search error 50 for dcp 110, 115 or mfc 210 here. its the same procedure.

Error message print unable 50

the encoder strip which gives the printhead the position is out of place (error 50). You have to open the printer and reinsert the strip:

Stick a 1.5 inch tape onto the printhead cover where the strip runs thru. This will prevent this accident in future!

Error message unable to print

Send it back. The printhead voltage is innnnn disorder. Netxt will be Error 41 (Every Error starting with 4 means probs with printhead and in 99,9% the head has to be changed and cant be fixed!)
