8.1Buffer Size

With the DIP switch, you can set either 6 K bytes or 256 bytes.

DIP switch segment 1-8 ON → 6K bytes

8.2Input 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.

8.3Clearing 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.
