The machine should show the black and white pattern on the LCD. 

NOTE:

 Never unplug the machine's or PC's power cord or the USB cable during writing.  

(1) Run "FILEDG32.exe." 

The Filedrgs window will appear as shown below. 

(2)  Drag and drop the firmware (e.g., LZ0023_A.upd) onto the BHL2-Maintenance Printer icon in 

the Filedrgs window shown above. 

NOTE:

 Use a firmware file after extracting.  It is a self-extracting file having the  

extension .exe.  Double-click the exe file to extract it. 

When writing operation starts, the machine beeps intermittently.  After approx. 2 to 5 minutes,  
the writing operation is complete and the machine automatically reboots and returns to the  
standby state.
