Introduction

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 insufficient 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.

1. Cautions regarding the installation location

Installation environment

s 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.

s 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: 10y430y
Ambient humidity: 40%470%
Optimum temperature and humidity: 20y, 65%

• If the machine is installed near to faucets, water heaters or humidifiers, 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.

s Avoid installing the machine in places with open flames, or where reflected heat or other hot air

currents (from stoves, etc), or cold air currents from coolers, etc will strike it directly.

s Avoid installing the machine in poorly ventilated places.
s Avoid installing the machine in dusty places.

s The machine should not be tilting when it is used.

*1:Time required to print the first sheet of paper

after the platemaking key is pressed.

A new, originally-developed superfine thermal
head gives beautifully accurate reproductions of
fine print and halftone photographs.

Its resolution is 400dpi in the pel path direction
and 400dpi in the line progression direction.

Its resolution is 300dpi in the pel path direction
and 600dpi in the line progression direction.

DP-430/DP-330

DP-440/DP-340

Adjusting the eject enables both thin and thick
sheets of paper to be aligned neatly.

A long-life, high-brightness xenon arc lamp is
used to illuminate the documents. Since the
lamp's intensity is not affected by temperature
variation*2, printing quality at low temperatures
is greatly enhanced*3.

*2: The lamp is filled with xenon gas, which means

that it does not require heat to vaporize mercury,
as a fluorescent lamp does, and therefore its
intensity does not vary with temperature.

*3: Increased viscosity of the ink at low temperatures

results in fainter printing than at normal
temperatures.

Operation is simplified by concealing
occasionally-used keys under a panel, leaving
just the basic function keys permanently
accessible.

zScanner Section

1. Description

The document is illuminated with the lamps, and the document reflection in proportion to the document
image darkness is imaged on the CCDs through the mirror and lens. Then it is resoluted into picture elements
and converted photoelectrically.Additionally the machine is equipped with 3 reflecting sensors that sense the
size of documents placed on the document glass.

• The optical system gose forward (to the left) or back ward with a stop position of scanner home
position sensor(PS1).

Optical System Operation

440340

• When ADF is attached, set the ADF Home Position Sensor (PS2) as the optical system stop position, and
then read the document darkness.

2) When image reading is complate, the lamp goes

out, but the optical system decelerates, then stops.
Following that, the optical system moves right
and returns to the home position.

3) The system is then on standby for the printing
process.

1)

When the

PLATEMAKING key

is pressed, the

optical

system will perform shading at home

position (PS1), and then move to the left.

3) After it returns, the optical system is then on
standby for the printing process.

2)

The optical system reads the image stopped at
home position (PS2). When image reading is

complete, it immediately moves to the right

and returns to the home position.
