LEAD-FREE SOLDER
The PWB’s of this model employs lead-free solder. The “LF” marks indicated on the PWB’s and the Service Manual mean “Lead-Free” solder.
The alphabet following the LF mark shows the kind of lead-free solder.

(1) NOTE FOR THE USE OF LEAD-FREE SOLDER THREAD
When repairing a lead-free solder PWB, use lead-free solder thread. Never use conventional lead solder thread, which may cause a
breakdown or an accident.
Since the melting point of lead-free solder thread is about 40°C higher than that of conventional lead solder thread, the use of the exclusive-use soldering iron is recommendable.
(2) NOTE FOR SOLDERING WORK
Since the melting point of lead-free solder is about 220°C, which is about 40°C higher than that of conventional lead solder, and its soldering capacity is inferior to conventional one, it is apt to keep the soldering iron in contact with the PWB for longer time. This may cause land
separation or may exceed the heat-resistive temperature of components. Use enough care to separate the soldering iron from the PWB
when completion of soldering is confirmed.
Since lead-free solder includes a greater quantity of tin, the iron tip may corrode easily. Turn ON/OFF the soldering iron power frequently.
If different-kind solder remains on the soldering iron tip, it is melted together with lead-free solder. To avoid this, clean the soldering iron tip
after completion of soldering work.
If the soldering iron tip is discolored black during soldering work, clean and file the tip with steel wool or a fine filer.
CAUTIONS
THERE IS A RISK OF EXPLOSION IF THE BATTERY
IS REPLACED BY AN INCORRECT TYPE.
PROPERLY DISPOSE OF USED BATTERIES ACCORDING
TO THE INSTRUCTIONS.

CHAPTER 3. MASTER RESET AND PROGRAM RESET
1. MASTER RESETTING
2. PROGRAM RESETTING (INITIALIZATION)
Master resetting clears the entire memory and resumes initial values.
This resetting resumes the initial program without clearing memory.
Master resetting can be accomplished by using the following procedure:
This resetting can be operated at below sequence in PGM mode.
Procedure A:
Procedure:
1)
Unplug the AC cord from the wall outlet.
1)
Unplug the AC cord from the wall outlet.
2)
Set the mode switch to the PGM position.
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.
3)
While holding down both JOURNAL FEED key and
RECEIPT FEED key, plugin the AC cord to the wall
outlet.
The master reset can also be accomplished in the following case.
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.
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 memories are lost and the machine does not
work properly after power recovery; this requires the master reset
operation.)

8. DRAWER
The A403 has a 1 channel of drawer port. (+ 1 channel is reserved for
the CPU PORT) O R No open sensor is provided.

ST0: 1st digit ~ ST6: 7th digit
• Display SEGMENT signal
10. A/D CONVERSION
The LED segment signal is outputted by writing SEGMENT data in
the /CS3 space.
The printer power supply voltage should be measured at more than 10
ms after the printer is turned ON.
