CHAPTER 1. MAINTENANCE
1. Preface
This manual provides Technical Service Information for model V8000 series.
This manual also provides procedures for removing and installing major components. Following these
procedures will minimize machine malfunctions. The information will also increase technical represen-
tatives' awareness and experience regarding repairs necessary to insure end-user satisfaction.

[1 - 3]
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.
CAUTION

[1 - 4]
CHAPTER 1. MAINTENANCE
!! 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. WARNING:
The back light tube of LCD of the Control Panel on this Model,
contains mercury which must be recycled or disposed of as hazardous waste.
3. 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.
Wire harness connector
FIRST
THEN
Press the ends.
Pressthe center,firmly.

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.

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
• Afterremoving wire bundles, fasten them
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, always replace it with 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, which re-
act to the magnetic force in magnets.
• Alwaysturnoff thepowerbeforeplugging
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
(Levelness of the floor: Within 2 degrees incline, and within 3mm difference in floor height.)
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.
