4. Simple operation
In the E series, a touch panel provides simple
operation.
In the S series, operation is simplified by concealing occasionally-used keys under a panel,
leaving just the basic function keys permanently accessible.
5. Fine Start Mode
This mode automatically sets optimum values for the following start conditions: timing of ink roller actuation during platemaking, number of no-paper rotations with the
ink roller actuated. These optimum settings
*3
are based on the room temperature
, the
length of time the printer was out of use, and
the number of prints last time it was used.
They ensure clear printing right from the
first sheet.
*3: Room temperature of 10ºC or below can cause
insufficient ink supply, even in Fine Start
Mode.

vMechanism
The machine carries out the processes of “platemaking” and “printing.”
Platemaking
In the “platemaking” process, the old master on the drum is removed while the
thermal head creates the scanned image on the new master and transfers it onto the
drum.
Chap.1 v Mechanism
Printing
In the “printing” process, paper separated from the stack by the paper feed roller and
the paper separator unit is pressed against the drum unit by the press roller. There are
small holes over only the image area of the master that is attached to the drum, and ink
that seeps from these holes is transferred to the paper. The paper is then peeled from
the master by the paper stripper finger and the top blow fan. The paper is directed onto
the paper ejection belt by a fan unit and discharged from the machine.

Chap.1 b Master
bMaster
1) Characteristics of the master
(1) Structure of the thermal master
(2) Functions and materials of the layers
Coated surface …… Prevents the film from fusing, being damaged due to friction,being peeled,
and being conveyed defectively due to electric static charge.
Material: silicon fluorine mold lubricant
Thermal film …… Holes are made by the heat of the thermal head.
Material: Polyethylene terephthalate (polyester)
Adhesive ………… 1] Adheres the film to the base.
2] Does not prevent ink from seeping.
3] Increases impression endurance.
Base ……………… 1] Base material for the master. Fibrous layer
2] Ink seeps the base.
(3) Cross section of the master during platemaking
Holes are made on the coated surface, thermal film and adhesive, while base fiber, base material
for the master, is left.
A part of the film fused by the thermal head is stuck to the head or banks up.
(4) Printed image
As the image consists of innumerable dots, it is taken as a continuous line through our eye.
INPORTANT :
•Precautions to be taken in dealing in the master.
(1) Do not put a heavy thing on the box in which masters are packed.
•This may damage the master and may cause defective platemaking.
(2) Do not leave the master as it is after it is taken out.
•Foreign objects are stuck to the master and this may cause defective platemaking.
(3) Keep the master from direct sunlight, too high or low temperature and too high or low humidity.
(Desirable storage temperature and humidity: 5-35 °C, 20-80%)
• If the master curls, defective plate attachment may occur.

Chap.1 n Ink
nInk
1) Characteristics of ink
(1) Ink for the digital printer is an emulsion type. It has a water-in-oil type structure.
(2) The surface active agent has two characteristics: hydrophilic group and lipophilic group in one molecule.
Oil and water bond together by these two characteristics as shown in the figure.
(3) Ink
(3) Ink viscosity is high at a low temperature and it is low at a high temperature. So when ink is used at a
low temperature (10°C or less), the amount of ink transferred to the paper is smaller and the print
darkness is slightly lighter.
When ink is used at a high temperature (30°C or more), the amount of ink transferred to the paper is
larger and the print darkness is slightly darker.
INPORTANT :
• Precautions to be taken in handling ink
(1) Storage environment
• When an emulsion type ink is stored at too high or low temperature for a long time, oil and water in the
ink pack may be isolated. Keep the ink from too high or low temperature (5°C or less, 35°C or more).
Also keep the ink from direct sunlight since the temperature rises sharply in the direct sunlight.
• When the water content is frozen, the water content is solidified and the bond characteristics decreases.
• When ink is stored at a high temperature, the bond characteristics decreases due to the change of the
surface conditions (surface tension, solubility). The bond characteristics also decreases due to evaporatin
of the water content.
(2) Precautions to be taken in handling the ink pack
• When the ink pack is removed from the drum unit to store, put the ink pack with its mouth up, screw
the cap firmly after expelling air from the ink tube. (If air is in the ink pack, water content is generated.)
