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 10°C (50°F) to
32.5°C (90.5°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
in Chapter
(2) The document is not damp.
(3) Short-grained paper or 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 may cause optically scanned image.
• Condensation on rollers 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, increase 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.
