CHAPTER 1. MAINTENANCE

[Handling of Lithium Battery]

- Never fail to follow the following instructions when you discard the used

lithium battery.

1. Never let the battery short-circuited.

If the (+) and (-) terminals contact each other or metal materials, the battery will

be short-circuited. If the batteries are collected and stored inorderly or one upon

another, the above-mentioned case will occur.

- DANGER -

If the battery is short-circuited, it will heat up and may in some cases explode into

fire.

2. Never heat up the battery.

- DANGER -

If you heat the battery up to more than 100°C or put it into the fire, it may burn

dangerously or explode.

3. Never disassemble the battery or press it into deformation.

- DANGER -

If you disassemble the battery, the gas pouring out of the inside may hurt your

throat or the negative lithium may heat up into fire.

If the battery is pressed into deformation, the liquid inside may leak out of the

sealed part or the battery may be short-circuited inside an explode.

4. Never fail to keep the battery out of reach of children.

If you put the battery within reach of children, they may swallow it down.

Should they swallow the battery, immediately consult the doctor.

[Replacement of the Lithium Battery]

1. The lithium battery must be replaced by a trained and authorized service

technician.

2. The battery must be replaced only with the same or equivalent type

recom- mended by the manufacturer.

3. Discard used batteries according to the manufacturer’s instructions.

!! WARNING !!

Important Safety Precautions

1. Always disconnect electrical supply before placing hands in the

machine.

I. To avoid injuries:

Be sure to disconnect the electrical power before disassembling, assembling,or when

making adjustments on the machine.

II. Protection of the machine:

Make sure to turn OFF the power to the machine before plugging or unplugging the

electrical connectors, or when connecting a Meter.

2. Always connect electrical connectors firmly.

I. To avoid electrical failure:

The connectors must be connected firmly together and onto the PCBs.

Press on the ends of the connectors and then on the middle to ensure a firm fit.

II. Protection of the electrical components:

The electrical components may be damaged due to short circuits caused by a loose

connector.

WORK PRECAUTIONS

2. Work Precautions

Inspection

If you discover any defects or problems during an inspection, fix the problems or if necessary take

steps such as replacing a part.

Removal

Check the problem area. At the same time, examine the cause of the problem and determine

whether the part needs to be removed or disassembled. Next proceed according to the proce-

dures presented in the Technical Manual. In cases where, for example, it is necessary to disas-

semble areas with large numbers of parts, parts which are similar to each other, or parts which are

the same on the left and right, sort the parts so that you do not mix them up during reassembly.

(1) Carefully sort the removed parts.

(2) Distinguish between parts which are being replaced and those which will be reused.

(3) When replacing screws, etc., be sure to use the

specified sizes.

Assembly and Installation

Unless specified otherwise, perform the removal proce-

dures in reverse during assembly and installation. In

cases where protrusions or holes are provided to assist

in positioning parts, use them for accurate positioning

and securing.

(Protrusions and holes for positioning parts Half

pierce section)

Tools

Using tools other than those specified can lead to injury

or damage screws and parts. Have all the tools neces-

sary for the work available.

CHAPTER 1. MAINTENANCE

Electrical system work

• Afterremovingwirebundles,fastenthem

with wire bundle bands (bar lock ties) so

that they will not sag.

• When installing parts, be careful to avoid

pinching or damaging the wire bundles.

• Ifa fuse blows, alwaysreplaceitwith one

with the specified capacity. Using a fuse

with a larger capacity can not only dam-

age parts, but may cause fires.

• Be careful not to drop image scanners,

thermal print heads, and other sensors

as they can be easily damaged.

Switch types

• Microswitchesmaybedividedbetweennor-

mallyopen(NO)typesandnormallyclosed

(NC) types.

With an NO connection, an internal con-

tact is connected when the switch actua-

tor is pressed.

With an NC connection, an internal con-

tact is disconnected when the switch ac-

tuator is pressed.

• Magnetic lead switches are switches in

which an internal contact is connected

in reaction to the magnetic force of a

magnet.

Sensor types

• Photo-electric sensors may be broadly

divided into the following four types: in-

terrupttypes (U-shaped), actuator types,

reflective types, and transmittive types.

• Magneticsensors use Hall ICs, whichre-

act to the magnetic force in magnets.

• Alwaysturnoffthepowerbeforeplugging

or unplugging sensor connectors.

CHAPTER 1. MAINTENANCE

Installation location

• Do not install the machine in any of the following locations.

(1) Those subject to direct sunlight or any bright location such as by a window (If you must

install in such a location, put a curtain or the like over the window.)

(2) Those where the temperature changes drastically

(3) Those that are too hot, cold, humid, or dry

RECOMMENDED:

Temperaturerange:15° centigrade - 30° centigrade

Humidity range: 40% - 70% No condensation allowed

(4) Those with radiant heat sources and any locations in the direct path of air from air condition-

ers, heaters

(5) Any poorly ventilated location

(6) Dusty atmosphere

(7) Any tilted location

(Installation height difference: 10 mm max. front - rear, 10 mm max. left - right)

Electrical connection

• Plug the plug securely into the socket so that there is no problem with the contact in the power

supply plug section.

• Do not use any triplets or extension cords.

• Do not allow any other machine to stand on or crush the power cord.

Ground connection

• Always ground this machine to prevent electrical shock in the unlikely event of electrical

leakage.
