The user can establish the internal Machine Error Code as follows: pull the mains cable out of the machine (power off), hold down the Menu/Set key, re-insert the mains cable into the machine (power on). The internal Machine Error Code will be displayed.
If that doesnt give you the code then try going into service mode by pressin menu key then *, 2 , 8, 6, 4  super quick!! Display goes blank or Maintenence mode is displayed, if not... not quick enough, do again to you get it, then press 77 start, error should display. press 99 to exit Maintence mode, dont play with other numbers!!

a couple of the most common errors are

Error 41 needs new print head costly

error 46 waste ink full, need new waste tank

Whats yours?

The most common reason for this error is that there is something obstructing the path of the print-head. Please check the paper carriage area for any objects such as a paper clip or torn pieces of paper. Sometimes after a paper jam you can have small bits of paper trapped under the print-head.

If you do not find any objects the next thing we want to find out is if the unit has an error code. Press menu * 2 8 6 4 within 3 seconds. You want to put the machine in a maintenance mode. All the lights should begin flashing. If the lights do not flash press the stop key and start all over again until the lights flash. Once the machine is in maintenance press the number 82 and it is going to give you an error code. If the unit has 00 then there is no error. If there is an error record the error code. Press stop and then 91 and this will reset your machine. Press stop and then 99 and this will exit you out of maintenance. If this does clear your error you will need to call Brother.
