The cause of most accidents is failure to adhere to basic safety rules and observe
safety instructions. It is important to prevent potential causes of accidents from
occurring. In order to do so, read this manual carefully, and be sure to understand
all the safety instructions and correct inspection and servicing procedures that it
provides before beginning repair or servicing work.
Repairing or servicing the machine with insufcient knowledge about it could lead to
unforeseen accidents.
It is not possible to anticipate and describe in a manual such as this every possible
hazard that could arise in the course of repair and servicing. Therefore, besides
observing the safety instructions marked in this manual and on the machine's labels,
service personnel should be safety-conscious and take other safety precautions as
necessary. When performing repair or service work not covered by this manual, you
should obtain safety guidance from an appropriately knowledgeable person.

If the instructions accompanying this symbol are ignored and the
machine is operated incorrectly, death or serious injury, or else material
damage, is likely to result.
A " " symbol tells you that a certain action is forbidden. Precisely what
is forbidden is indicated by a picture inside the symbol (in the example
here, the picture means that disassembly is forbidden), or in writing at
the side of the symbol.
A "●" symbol means that a certain action is forbidden and/or that
a specific instruction must be followed. The specific instruction is
indicated by a picture inside the symbol (in the example here, the
instruction is "Remove the power plug from the socket").
●This manual contains the following information: structure and function of major parts,
disassembly and reassembly procedures, specications, and procedures for adjustment,
maintenance, inspection and corrective action. This information is current as of April
2014, and applies basically to the model DD5450/5440. From time to time, parts are
changed to improve quality, performance or safety.
Note therefore that in some cases, certain parts or machine structure aspects described
in the text or illustrations of this manual may not be precisely the same as the product
being serviced.
●Safety instructions marked with a " " (WARNINGS and CAUTIONS) are very important
for safety and must be observed.

Safety instructions
CAUTION
Installation environment
► Avoid installing the machine in places exposed to direct sunlight.
● Sunlight will cause the temperature in the machine's interior to rise, possibly leading to
malfunction of the control system.
● Sunlight could cause misoperation of the sensors.
● The heat of direct sunlight could cause deformation of the machine's plastic parts.
*Also avoid installation near to a ground glass window; light and heat penetrate such
windows although they are opaque.
► Avoid installing the machine in places subject to high or low temperature or humidity.
● High or low temperature or humidity could cause the machine to operate abnormally.
Suitable temperature and humidity ranges are:
Ambient temperature: 10oC-35oC
Ambient humidity: 40%-70%
Optimum temperature and humidity: 20oC, 65%
● If the machine is installed near to faucets, water heaters or humidiers, or in cool (sunless)
parts of a building or in the vicinity of water sources, the paper could absorb moisture and
curl, leading to misfeeds or poor image quality.
► Avoid installing the machine in places with open ames, or where reected heat or other
hot air currents (from stoves, etc), or cold air currents from air conditioners, etc will strike it
directly.
► Avoid installing the machine in poorly ventilated places.
► Avoid installing the machine in dusty places.
► The machine should not be tilting when it is used.
● Install the machine so that it is level.
(The machine should be level to within 5mm in the front-rear direction, and 5mm in the
lateral direction.)
► Do not install the machine on shaky, sloping or otherwise unstable surfaces.
● The machine could fall over on such surfaces, or fall off them, causing injury.

WARNING
● The machine's power supply voltage and power consumption depend on the model.
Details of this are given in the tables below. The power supply voltage and power
consumption for the machine are given in the table below. The machine's power supply
voltage is indicated on the rating label located on the machine's left side; the machine
must be connected to a power supply of the voltage indicated.
→ Otherwise, re or electric shock could result.
If the power supply voltage is unstable or if the power supply has insufcient capacity, the
machine may not operate normally.
Make sure that the power supply has sufcient capacity for the system as a whole, including
optional equipment.
*1“With no load” - when the machine is on standby.
“At full load” - when the machine is running at maximum power consumption.
*2Basic type with a computer unconnected
● Use only the power cord that is provided among the accessories.
Insert the power cord plug rmly into the socket, so that proper electrical contact is effected.
● Install the machine close to its power supply. The outlet used should be exclusively for the
machine, and have no other equipment connected to it.
If an extension cord is necessary, it should have a ground terminal, and be of the following
ratings:
* For a 120V AC model: 130V, at least 15A, length not exceeding 5m.
* For a 230V AC model: 250V, at least 8A, length not exceeding 5m.
• Never tread on the power cord or pinch it between other objects, or accidents could result.
