Reloading Process - Brother HL-1870n Network User's Manual

APPENDIX

Reloading process

The Data LED on the printer control panel will blink during the firmware file
loading process. During programming process, the Backlit of LCD goes off, and
"Erase xxxxxx" and "Write xxxxxx" wll be indicated alternately. After the
firmware update is completed, the printer will re-start automatically. DO NOT
TURN OFF THE PRINTER DURING THESE PROCESSES.
If the Data LED does not stop blinking after about two minutes, check to make
sure that you correctly entered all parameters and that your network connections
are good. Then power the print server/printer off and then on again, to retry the
download.
If you encounter problems upgrading the firmware and you find that the network
portion of the printer no longer functions, you should try re-programming the
print server by using the COPY command from the DOS prompt of your PC. To
do this, connect a parallel cable between your PC and printer and use the
command "COPY filename LPT1:/B" (where filename is the new firmware file).
