Chapter 5 Downloading Software If Flash Contains Only Boot or Corrupt Code
Downloading Software If Flash Contains Only Boot or
Corrupt Code
If the flash memory contains only boot code (e.g., if it is new), or if a download
was interrupted (e.g., by a power outage), you must download software
through the printer’s parallel port using the three-key initialization sequence
covered in this section.
1. Make sure the printer’s parallel port is available.
2. Set the printer power switch to O (Off).
3. Disconnect the data (signal) cable(s) from the printer interface
connectors.
4. Connect a parallel data printer cable to the LPT1 port of a computer
running the Windows (95, 98, Me, NT, 2000, XP, Server 2003, or Vista)
operating system.
5. Connect the data cable to the Centronics port of the printer.
6. On the printer control panel, press and hold the DOWN key, the
↵
key,
and key. Without releasing the keys, power the printer on. When you
see “SDRAM TEST” or “B20 FIRMWARE DOWNLOAD” on the LCD,
release the keys.
7. Using Windows Explorer, create a directory named download at the root
level of your C: hard drive ( C:\download ).
8. Insert the printer emulation software CD into your computer’s CD drive.
9. Select the emulation set you want to download into the printer. The
filename is a six digit number plus
.exe . For example: 123456.exe
This is the file you will download into the printer.
10. Copy the file to the download directory you created in step 7.
11. Start a command prompt session. (The Start Menu icon is usually labeled
Command Prompt or MS-DOS Prompt .)
12. At the command prompt type:
C: <Enter>
cd \download <Enter>
13. Enter the following command:
filename.exe -pb <Enter>
where filename .exe is the file name you noted in step 8. This command
decompresses the file on the hard drive and copies it as a binary file into
the flash memory on the printer controller board.
14. After the software successfully loads into flash memory, the printer will
reset itself.
NOTE: For SL4M printers, the RFID reader firmware will not upgrade using
this download method. If the RFID reader needs to be upgraded,
repeat the download process using one of the methods described
earlier after completing the three-key download.
