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.

When you want to clear the data in the input buffer, turn on the power, holding down the LF
switch. A buzzer will sound to inform you that the input buffer has been cleared. Hold down
the LF switch until the buzzer sounds.
If the printer prints the data erroneously at power-on, clear the input buffer as described
above, and then, re-input the data.
