Reloading process

The Data LED on the printer control panel will blink during the 
firmware file loading process. During programming process, the 
backlight on the printer’s LCD goes off, and 

Erase xxxxxx

 and 

Write 

xxxxxx

 will be indicated alternately on the LCD. 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).
