1 INTRODUCTION

1.1. SAFETY PRECAUTIONS

1. Before servicing, unplug the AC power cord to prevent an electric shock.

2. When replacing parts, use only the manufacturer´s recommended components.

3. Check the condition of the power cord. Replace if wear or damage is evident.

4. After servicing, be sure to restore the lead dress, insulation barriers, insulation papers, shields, etc.

5. Before returning the serviced equipment to the customer, be sure to perform the following insulation resistance test to prevent the customer from being exposed to shock hazards.

1.2. INSULATION RESISTANCE TEST

1. Unplug the power cord and short the two prongs of the plug with a jumper wire.

2. Turn on the power switch.

3. Measure the resistance value with an ohmmeter between the jumpered AC plug and each exposed metal cabinet part (screw heads, control shafts, bottom frame, etc.).

Note: Some exposed parts may be isolated from the chassis by design. These will read infinity.

4. If the measurement is outside the specified limits, there is a possibility of a shock hazard. The equipment should be repaired and rechecked before it is returned to the customer.

1.3. FOR SERVICE TECHNICIANS

ICs and LSIs are vulnerable to static electricity. When repairing, the following precautions will help prevent recurring malfunctions.

1. Cover the plastic part´s boxes with aluminum foil.

2. Ground the soldering irons.

3. Use a conductive mat on the worktable.

4. Do not touch the IC or LSI pins with bare fingers.

1.4. BATTERY CAUTION

CAUTION

Danger of explosion if battery is incorrectly replaced.

Replace only with the same or equivalent type recommended by the manufacture. Dispose of used batteries according to the manufacturer´s instructions.

KX-FT63BX / KX-FT63BX-W

1.5. AC CAUTION

For safety, before closing the lower cabinet, please make sure of the following precautions.

(1) The earth lead is fixed with the screw. (2) The AC connector is connected properly. (3) Wrap the AC lead around the core 2 times.

KX-FT63BX / KX-FT63BX-W

1.6. PERSONAL SAFETY PRECAUTIONS

1.6.1. MOVING SECTIONS OF THE UNIT

Be careful not to let your hair, clothes, fingers, accessories, etc., become caught in any moving sections of the unit. The moving sections of the unit are the rollers and a gear. There is a separation roller and a document feed roller which are rotated by the document feed motor. A gear rotates the two rollers. Be careful not to touch them with your hands, especially when the unit is operating.

1.6.2. LIVE ELECTRICAL SECTIONS

All the electrical sections of the unit supplied with AC power by the AC power cord are live. Never disassemble the unit for service with the AC power supply plugged in.

2.3. TROUBLESHOOTING DETAILS

2.3.1. OUTLINE

Troubleshooting guide provides a logical path of deduction to assist in locating a fault and suggests methods of restoring the unit to full working condition. Use the reported symptoms of the fault to determine the best troubleshooting method. Even difficult faults can be tracked to a specific block or area, for example, the "Digital Board" or "Image Sensor".

A variety of fault descriptions from customers often point to the same area and, for this reason, careful analysis of the reported

symptoms is required. After every repair, test all functions to ensure no problems are evident.

2.3.2. STARTING TROUBLESHOOTING

Select the appropriate troubleshooting method according to the symptoms.
