1.4.10 Updating of Firmware Using an External Memory (Function code 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 has been replaced or for
operations using a PC, refer to
Operating Procedure
(1) Switch your PC ON 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 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.
