CHAPTER 3. MASTER RESET AND PROGRAM RESET
1. MASTER RESETTING
Master resetting clears the entire memory and resumes initial values.
Master resetting can be accomplished by using the following procedure:
The master reset can also be accomplished in the following case.
In case power failure occurs when the machine has no battery
attached to it, the master reset operation is automatically performed
after the power has been plugined the AC cord to the wall outlet.
(This is because if power failure occurs with no battery attached to
the machine, all the memories are lost and the machine does not
the machine, all the memories are lost and the machine does not
work properly after power recovery; this requires the master reset
operation.)
2. PROGRAM RESETTING (INITIALIZATION)
This resetting resumes the initial program without clearing memory.
This resetting can be operated at below sequence in PGM mode.
Note: In case power failure occurs when the machine has no battery
attached to it, the master reset operation is automatically per-
formed after the power has been restored.

* Do not turn on without paper.
* THERMAL HEAD power supply control : Turns ON when P81= “H”;
turns OFF when “L”. (The power supply for HEAD and STEPPING
MOTOR is shared). When printing is finished (when the motor is
