2. Warning

!! 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.

CHAPTER 1: MAINTENANCE

3. Work Precautions

When conducting maintenance work, be careful to avoid injury caused by springs or the sharp edges

of sheet metal.

Inspection

Ifyoudiscoveranydefectsorproblemsduringaninspection,x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 procedures presented

in the Technical Manual. In cases where, for example, it is necessary to disassemble 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speciedsizes.

Assembly and Installation

Unlessspeciedotherwise,performtheremovalprocedures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 pierced section)

Tools

CHAPTER 1: MAINTENANCE

Electrical system work

> After removing 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.

> If a fuse blows, always replace it with one with

thespeciedcapacity.

> Using a fuse with a larger capacity can not only

damageparts,butmaycauseres.

> Be careful not to drop image scanners, thermal

print heads, and other sensors as they can be

easily damaged.

Wiring bundle bands

(bar lock ties)

Sensor types

> Photoelectric sensors may be broadly divided

into the following four types: interrupt types

(U-shaped),actuatortypes,reectivetypes,

and transmitting types.

> Magnetic sensors use Hall ICs, which react to

the magnetic force in magnets.

> Always turn off the power before plugging or

unplugging sensor connectors.

Note

The machine is comprised of many gears. When inspecting or replacing parts, apply grease to the gears.

If they are not properly greased, the gears may make abnormal sounds, and malfunctions or mechanical

problems may occur.

CHAPTER 1: MAINTENANCE

4. 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:

Temperature range: 15 degrees Celsius - 30 degrees Celsius

Humidity range: 40% - 70% No condensation allowed

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

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 case of an electrical leakage.
