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
(screwheads, 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.
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 the battery is replaced incorrectly. Replace only with the same or equivalent type recommended by the
manufacturer. Discard used batteries according to following caution:
Disposal of lithium batteries should be performed by permitted, professional disposal firms knowledgeable in state government
federal and local hazardous materials and hazardous waste transportation and disposal requirements.
A battery continues to have no transportation limitations as long as it is separated to prevent short circuits and packed in strong
packaging.
Commercial firms that dispose of any quantity of lithium cells should have a mechanism in place to account for their ultimate
disposition. This is a good practice for all types of commercial or industrial waste.

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 earth lead around the core 3 times.

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.
CAUTION:
AC voltage is supplied to the primary side of the power supply unit. Therefore, always unplug the AC power cord before
disassembling for service.

1.7. SERVICE PRECAUTIONS
1.7.1. PRECAUTIONS TO PREVENT DAMAGE FROM STATIC ELECTRICITY
Electrical charges accumulate on a person. For instance, clothes rubbing together can damage electric elements or change their
electrical characteristics. In order to prevent static electricity, touch a metallic part that is grounded to release the static electricity.
Never touch the electrical sections such as the power supply unit, etc.
