To Load Programs Using An External Memory - Brother MFC5890CN Service Manual

Note: If loading operation ends abnormally, turn the machine off and on. Wait for the
machine to emit a long beep and automatically enter the firmware loading mode, and then
perform the loading procedure above again.

To load programs using an external memory

(1) Insert an external memory to your PC.
(2) Create a folder named "BROTHER" in the top layer of the external memory's
directory and copy the firmware file having the extension .pjl into that folder.
NOTE: Before copying, check that the file name of the firmware matches with your
machine. Be sure to save only one firmware file having the extension .pjl in the
"BROTHER" folder. Otherwise, the firmware cannot be updated correctly.
TIP: If a firmware file not matching the machine is used, the firmware cannot be
updated, but note that you can superficially continue the operation until step (5)
below without any error.
(3) Remove the external memory from the PC and insert it into the machine in the initial
stage of the maintenance mode.
NOTE: Do not insert more than one external memory at a time.
NOTE: One external memory should be exclusively used for one machine. Do not
use one external memory for more than one machine.
(4) On the machine, press the 2 and 8 keys in this order.
The file name ********.pjl appears on the LCD. Check that ******** is identical
with the file name that has been copied into the external memory.
(5) Press the Black Start (Mono Start) key.
The "Receiving Data" appears on the LCD, and after a while, "Program Updating"
appears.
NOTE: Pressing the Color Start key does not start updating.
NOTE: Never remove the external memory from the machine when the updating is
in progress.
(6) Updating will complete in a few minutes, and the machine automatically restarts and
returns to the standby state.
Remove the external memory from the machine and store it in a safe place.
NOTE 1: If any of the error messages listed below appears, press the Stop/Exit key, and
the machine returns to the initial stage of the maintenance mode.
