8. INPUT BUFFER BACKUP FUNCTION
8.1 Buffer Size
With the DIP switch, you can set either 6 K bytes or 256 bytes.
DIP switch segment 1-8 ON → 6K bytes
OFF → 256 bytes
8.2 Input Buffer Backup
Even if the power is turned off or fails during the printing process, the data in the input buffer will be saved.
If the power is turned on again, the printer will print a power failure mark, "==POWER DOWN==" in red
and reprints the data from the beginning of the line where it left off.
8.3 Clearing the Input Buffer
When you want to clear the data in the input buffer, turn on the power while holding down the SEL switch.
The following messages will be printed to notify that the input buffer is cleared.
“Clear Data in Buffer”
“Cleared Data in Buffer”
If the printer prints the data erroneously at power-on, clear the input buffer as described above, and
then, re-input the data..
