5.8 Downloading Firmware and Fonts
The Printer stores the printer’s Boot Loader, Operating Program, and Font
firmware in flash memory located on the main PCB. This allows an operator to
update the printer’s firmware through the printer’s parallel port. These updates
will include bug fixes and/or new features. The following procedure can be used
to update the Boot Loader, Operating Program, and Font firmware by
substituting the correct filenames.
Updating Instructions:
1.
Identifying the New Firmware
- Firmware program updates and new
features are available from our web site. Simply download the desired
version on to your computer’s hard drive or a floppy disk.
2.
Placing Printer into Download Mode
– Press and hold the Pause and
Cancel buttons simultaneously while powering up the printer. All three
indicators on the printer should be on.
3.
Downloading
– The printer is now ready to accept new printer firmware.
Using the DOS copy command enter:
copy filename.dlf lpt1/b
After the download starts the Paused and Fault lights will turn off. Once the
download is complete the printer will turn on the Paused light (indicating a
successful download) or the Fault light (indicating an unsuccessful download).
If the download fails (i.e. Fault light on) simply send the file again, if the
download continues to fail here are some possible causes:
1.
Invalid or corrupted file being downloaded.
Make sure the file you are downloading to the printer is correct and
applicable for your printer model.
2.
Communications errors.
Check the cable connections on the host computer and the printer. Be sure
to use a quality-shielded cable.
3.
The Printer could not successfully write to or erase the flash memory.
Flash chips or main PCB defective. Try again and if problem persists call
for service.
