INTRODUCTION
SAFETY PRECAUTIONS
1. Before servicing, unplug the 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.
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, handle brackets, 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.
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 parts boxes with aluminum foil.
2) Ground the soldering irons.
3) Use a conductive mat on the worktable.
4) Do not touch IC or LSI pins with bare fingers.

BATTERY CAUTION
CAUTION
Danger of explosion if battery is incorrectly replaced. Replace only with the same or equivalent type recommended by the
manufacture. Discard used batteries according to following caution:
Disposal of lithium batteries should be performed by permitted, professional disposal firms knowledgeable in state govern-
ment federal and local hazardous materials and hazardous waste transportation and disposal requirements.
Battery continues to have no transportation limitations as long as they are 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 ulti-
mate disposition. This is a good practice for all types of commercial or industrial waste.

PERSONAL SAFETY PRECAUTIONS
Be careful not to let your hair, clothes fingers, accessories, etc., become caught in any moving sections of the unit.
These are driven by the carriage monitor, and the slow down gear, the paper feed roller, the pressure roller, the eject roller,
the spur, the pick-up roller, etc., which are driven by the paper feed motor. These separation roller and document feed roller
which are rotated by the document feed motor and a gear which makes the two rollers rotate.
Also, the spurs are metal and sharply pointed. Be careful not to touch them accidentally by hand.
If your Panasonic battery is fully charged;
While in use (TALK) Up to about 2.5 hours
While not in use (Stand-By) Up to about 4 days
EBattery life may vary depending on usage conditions and ambient temperature.
EClean the handset and the main unit charge contacts with a dry soft cloth once a
month, or the battery may not charge properly.
EOnce the battery is fully charged, you do not have to place the handset on the main unit until
the TALK/BATT LOW indicator flashes slowly.
EThe battery cannot be overcharged.

1. TROUBLESHOOTING SUMMARY
1-1. TROUBLESHOOTING
After having confirmed the abnormal condition by asking the user, troubleshoot according to the instructions in
Observe the following precautions when troubleshooting.
1-2. PRECAUTIONS
1) If there is trouble with the print quality or the paper feed, first check that the installation space and the print
paper meets the specifications, that the paper selection lever/paper thickness lever is set correctly, and that the
paper is set correctly without any looseness.
2) Before troubleshooting, first check that the connectors and cables are connected correctly without any looseness.
Especially, if the abnormality occurs randomly, check very carefully.
3) When connecting the AC power cord with the unit case and checking the operation, exercise utmost care in
handling the electric parts in order to avoid electric shock and short-circuits.
4) After troubleshooting, double check that you have not forgotten any connectors, left any loose screws, etc.
5) And always test to verify that the unit is working normally.

3. DETAIL OF TROUBLESHOOTING
3-1.OUTLINE
Troubleshooting is to make quality and reliability recover by finding out the broken component and exchange or
adjustment or cleaning. We have to find out symptoms and then arrange troubleshooting method.
If it's tough to finding out just a broken component, we should so arrange that block or section are specified, for
example "digital board" or image sensor".
A claim tag from customer or dealer gives us many kinds of expression for same trouble. Because they are not
technician or engineer. But we should carefully read it on our supposition comes from experience, and sufficiently
test the function related to that tag. Returns from customer or dealers often have to claim tag. In this case we need
to find out the symptoms. Therefore please test the unit following simple-check-list. A problem difficult to find out
may lurk, so we need to test repeatedly, for example make copy 10 pages or receiving 10 pages,.........
