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.

Example:

Solder composition Sn-Ag-Cu Sn-Ag-Bi

Sn-Ag-Bi-Cu Sn-Zn-Bi Sn-In-Ag-Bi Sn-Cu-Ni Sn-Ag-Sb Bi-Sn-Ag-P

Bi-Sn-Ag

5mm

Solder composition code (Refer to the table at the right.)

(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.

Solder composition code

i n s

(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 f rom 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

Master resetting clears the entire memory and resumes initial 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 memories are lost and the machine does not work properly after power recovery; this requires the master res et 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 OFF by using the regulator IC.)
