Flash Download Commands
These commands are used to load firmware into the printer and to configure
the printer. With the exception of the Put the Printer in Flash Download Mode
command (1B 5B 7D), these commands are available only when the printer is in
download mode. No other commands are available in download mode.
Download mode can be entered in one of two ways:
•
Set the external switches to a special diagnostic setting and power on the
printer.
See “Flash Download Mode” in section 3 for more information
•
Send the command (available in all emulations), Put the Printer in Flash
Download Mode (1B 5B 7D) when the printer is in normal operating mode.
This command is described in this section.
Note: The EFP9800 FLASHLOAD software utility can also be used for
downloading firmware to the unit. The utility is included in the
EFP9800-SW1 style package.
