CHAPTER 3. MASTER RESET AND PROGRAM RESET
Service Manual
[1] MASTER RESETTING
Master resetting clears the entire memory and resumes default values.
Master resetting can be accomplished by using the following procedure:
Procedure A: 1) Unplug the AC cord from the wall outlet.
2) Set the mode switch to the PGM position.
3) While holding down both the JOURNAL FEED key
and [CL] key, plugin the AC cord to the wall outlet.
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 restored.
(This is because if power failure occurs with no battery attached to the
machine, all the memory will be 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.
Procedure: 1) Unplug the AC cord from the wall outlet.
2) Set the mode switch to the PGM position.
3) While holding down both JOURNAL FEED key
and RECEIPT FEED key, plugin the AC cord to
the wall outlet.
NOTE: 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 restored.

turns OFF when "L". (The power supply for HEAD and STEPPING
MOTOR is shared). When printing is finished (when the motor is
stopped) Athe power should be turned OFF.
* Before printing or feeding paper, perform A/D conversion in ** ms
after the printer head is turned ON and make sure the voltage is
stable.
(The power supply of the printer head should be turned ON and
