electrical shock, burn or suffocation.
WARNING
DO NOT expose the machine to direct sunlight, excessive heat, open flames,
corrosive gasses, moisture or dust.
DO NOT place your machine on a carpet or rug, as this will expose it to dust. Doing
so may create a risk of an electrical short or fire. It may also damage the machine
and/or render it inoperable.
DO NOT place the machine near heaters, air conditioners, electric fans, refrigerators,
radiators, or water. Doing so may create the risk of a electrical short or fire should
water come into contact with the machine (including condensation from heating, air
conditioning, and/or ventilation equipment that may be sufficient to create a electrical
shock, short circuit or fire).
DO NOT place the machine near chemicals or in a place where chemicals could be
spilled on it. Should chemicals come into contact with the machine, there may be a
risk of fire or electric shock. In particular, organic solvents or liquids such as benzene,
paint thinner, polish remover, or deodorizer may melt or dissolve the plastic cover
and/or cables, resulting in a risk of fire or electric shock. These or other chemicals
may also cause the machine to malfunction or become discolored.
The product should be placed so as not to come into contact with any wall or other
device. Otherwise, it could create a risk of overheating and/or fire.

1. INTRODUCTION
Troubleshooting is a collection of solution procedures that service personnel should follow if
an error or malfunction occurs in the machine. It is difficult to determine troubleshooting
procedures for all possible problems that may occur in the future. Therefore, this chapter
describes typical problem cases and recovery procedures for these. These will help service
personnel identify and repair other similar defective sections.
1.1
Precautions
Be sure to observe the following precautions to prevent any secondary problems occurring
during troubleshooting:
(1) Be sure to unplug the AC power cord before removing any covers or PCBs, adjusting the
machine, or conducting continuity tests using a tester.
(2) Do not hold the cable when connecting or disconnecting the cable. Be sure to hold the
connector.
(3) Static electricity charged in your body may damage electronic parts.
Before handling the PCBs, touch a metal section of the machine to discharge static
electricity.
When transporting PCBs, be sure to wrap them in conductive sheets.
When replacing PCBs, wear a grounding wrist band and perform replacement on a
conductive mat. Also take care not to touch the conductor sections on the flat cables.
(4) Be sure to always observe all warnings.
(5) After repair is completed, check that the repaired sections operate normally.
2-1
Confidential
1.2
Checks before Commencing Troubleshooting
Check the following items before commencing repairs on the machine.
Operating environment
(1) The machine is placed on a flat, stable surface.
(2) The machine is used in a clean environment where the temperature is between 5°C
(41°F) and 35°C (95°F) and the relative humidity is maintained between 20% and 80%.
(3) The machine is not exposed to direct sunlight, excessive heat, moisture, or dust.
(4) Hold the machine level while moving it.
Power supply
(1) Power described on the rating label attached on the machine is supplied. Power
fluctuation should be within ±10% of the rated voltage.
(2) The AC input power supply is within the regulated value.
(3) The cables and harnesses are connected correctly.
(4) The fuses are not blown.
Document
(1) The recommended paper is used for the document. (Refer to "1.5.2 Media
specifications" in Chapter 1.)
(2) The document is not damp.
(3) Acid paper is not used.
Others
(1) Condensation
When the machine is moved to a warm room from a cold location, condensation may
occur inside the machine, causing various problems as listed below.
• Condensation on the surface of optical devices such as the CIS glass and CIS unit
may result in poor quality of scanned images.
• Condensation on the pick-up roller or separation pad may cause document feed
problems.
If condensation has formed in the machine, leave the machine for at least two hours
until it reaches room temperature.
(2) Low temperature
The motor may not operate normally in a cold environment because too much load is
applied to each drive. In this case, raise the room temperature.
Cleaning
Use a soft lint-free cloth.
WARNING
DO NOT use any flammable spray or flammable solvent such as alcohol, benzine,
or thinner to clean the machine. DO NOT use these articles near the machine.

1. SAFETY PRECAUTIONS
To avoid creating secondary problems by mishandling, follow the warnings and precautions
below during maintenance work.
• Be careful not to lose screws, washers, or other parts removed.
• Be sure to apply grease to applicable positions specified in this chapter.
• When using soldering irons or other heat-generating tools, take care not to accidentally
damage parts such as wires, PCBs and covers.
• Static electricity charged in your body may damage electronic parts. When transporting
PCBs, be sure to wrap them in conductive sheets.
• When replacing the PCB and all the other related parts, put on a grounding wrist band and
perform the job on a static mat. Also take care not to touch the conductor sections on the
flat cables or on the wire harnesses.
• After disconnecting flat cables, check that each cable is not damaged at its end or shortcircuited.
• When connecting flat cables, do not insert them at an angle. After insertion, check that the
cables are not at an angle.
• When connecting or disconnecting harnesses, hold the connector body, not the cables. If
the connector is locked, release it first.
• After a repair, check not only the repaired portion but also harness treatment. Also check
that other related portions are functioning properly.
• After assembly, it is recommended to conduct dielectric test and continuity test.
