Operational Procedures
Note: In this download mode, the printer will only accept data on the RS232
serial port. A second level loader, described in more detail in the command
Epic 430 OEM Integration Manual
section of the , supports the USB interface.
Note: In rare cases, it may be required to load the firmware twice. The Epic
TM
430 contains a flash file system. The complete flash image is sometimes
distributed as part of a firmware update. If the file system image is not
compatible with the previous firmware configuration, the new firmware may
need to reformat the file system. If this occurs, the firmware will have to be
reloaded after the flash is reformatted. The indications that this is happening
will be excessively long startup after a firmware update after which the printer
will not print: tickets are presented, however only graphics are printed, and
fonts will be missing. In this case it is important that the reformat be allowed to
complete, as it can take up to 30 seconds to reformat the entire flash system.
