1.3.10 Updating of Firmware Using an External Memory (Maintenance mode 28)
< Function >
This function updates firmware stored in the flash ROM on the main PCB using an
external memory (memory card or USB flash memory). It enables updating of firmware
without connecting the machine to a PC.
Tip: For instructions on how to update firmware when the main PCB ASSY has been
replaced or for operations using a PC, refer to Chapter 4, Section 1.3 "Install the
firmware (Maintenance mode 28)."
< Operating Procedure >
(1) Turn ON your PC and insert an external memory.
(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 firmware file name having the extension .pjl
matches your machine. The number of files having the extension .pjl in the
"BROTHER" folder should be 100 or less.
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.
(4) On the machine, press the 2 and 8 keys in this order.

Updating."
Note: Never remove the external memory from the machine when updating is in
progress.
(7) 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: If any of the error messages listed below appears, press the X key, and the
machine returns to the initial stage of the maintenance mode.
Note: After the completion of firmware updating, a file named "mfu-send.log" (which
stores the execution log) is created in the layer right below the "BROTHER"
folder.
