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

Safety Instructions
1. Cautions regarding the installation location
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 : 10°C–30°C
Ambient humidity : 40%–70%
Optimum temperature and humidity : 20°C, 65%
If the machine is installed near to faucets, water heaters or humidifi ers, or in cool (sunless)
•
of a building or in the vicinity of water sources, the paper could absorb moisture and curl,
parts
leading
●
● 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 5 mm in the front-rear
•
direction, and 5 mm 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.
to misfeeds.
Avoid installing the machine in places with open fl ames, or where refl ected heat or other
hot air currents (from stoves, etc), or cold air currents from coolers, etc will strike
it directly.

2. Cautions for installation work
WARNING
● The machine’s power supply voltage and power consumption are given in the table
below. The machine's power supply voltage is indicated on the identifi cation plate on
machine; the machine must be connected to a power supply of the voltage indicated.
→ Otherwise, fi re or electric shock could result.
If the power supply voltage is unstable or if the power supply has insuffi cient capacity, the
machine may not operate normally. Make sure that the power supply has suffi cient capacity
for the system as whole, including optional equipment.

Power consumption
Standby energy
● Use only the power cord that is provided with the accessories. Insert the power cord
plug fi rmly into the socket, so that proper electrical contact is made. Use of any other
power cord could result in imperfect grounding. If grounding is imperfect and
electrical leakage occurs, fi re or electric shock could result.
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 120 VAC model: 130 V, at least 15 A, length not exceeding 5 m
• For a 230 VAC model: 250 V, at least 8 A, length not exceeding 5 m
● Never tread on the power cord or pinch it between other objects, or accidents could
result.

Paper Curl
Due to the automated slitter function, the paper path of the DC-616 is sensitive to paper curl.
If paper curl is causing paper jams, the following are suggestions for remedying the problem:
1. Adjust the printing devices de-curler (if available).
2. Manually de-curl the stock before loading in the fe tray.
3. Turn the paper over (reprogramming the job may be necessary).
4. Use different paper stock.

Chapter 2 1 Paper Feed Section
1 Paper Feed Section
1. Description
Paper feed section feeds the paper into the machine
after separating each sheet of paper by air knife.
This is done through the operation of the air suction
mechanism and the air blow duct mechanism.
2. Operation
Air blow duct mechanism blows the compressed
air to the paper from the front side to create some
gap between the papers. The separated paper is
transferred when the shutter solenoid and the feed
motor provided in the air suction mechanism are
turned ON.
3. Operation of Each Part
1. Level Sensor
<Operation>
• Detect the top of the paper on the feed tray
When the feed tray rises to the extent that the
actuator is lifted up by the paper, the sensor comes
to the “light blocked” state.
Once the topmost sheet of paper is detected, the
rising motion of the feed tray is stopped.
• Detect the low level of paper
The actuator comes down as the paper level gets
low until the sensor comes to the “light through”
state. Once the sensor comes to the “light through”
state, the feed tray rises until the sensor comes
to the “light blocked” state. “E02” (elevator error)
appears on the display if the topmost paper sensor
does not switch to the “light blocked” state within 10
seconds after the transmission of feed tray go-up
command.

If the topmost sheet of paper cannot be detected, and
the feed tray continues to go up, the air suction unit
is pulled away from the elevator upper limit switch to
come to the “OFF” state.
The elevator upper limit switch stops the machine
operation immediately once it comes to the “OFF”
state.

4. Elevator Lower Switch
<Operation>
As the feed tray goes up, the angle is pulled away
from the elevator lower limit switch to come to the
“OFF” state. As the feed tray goes down to reach the
lower limit, the angle pushes the switch actuator to
trigger the “ON” state. “E02” (elevator error) appears
on the display if the angle does not push the elevator
lower limit switch actuator within 30 seconds after the
transmission of the feed tray go-down command.

<Operation>
Normally the feed tray goes up and down
automatically. However, it may be lowered by the
elevator down switch as required, including the case
of paper jam.

6. Shutter Solenoid
<Operation>
The suction solenoid is turned ON as the level sensor
is turned ON and the paper feed is ready.
Then, the valve opens to suck up the paper.
The valve is closed by the timer after the transferred
paper passes through the PPS2.

<Operation>
While the light goes through at PPS1, LED on the

light is blocked at the PPS1, the start key lights up in
green.
* Wipe off the dirt or contamination, if any, on the
PPS sensor with a rag.

Chapter 2 2 Double-Feed Detection Section (Option)
2 Double Feed Detection Section (Option)
1. Description
The double feed detection sensor is provided at the
ejection side of feed belt.
An ultrasonic sensor is used, and no adjustment for
fi tting it to the particular type of paper, and no input of
the paper thickness are required.
2. Operation
Whenever the ultrasonic sensor detects double feed,
the machine stops the operation.
3. Operation of Each Part
1. Double Feed Sensor
<Operation>
Whenever the ultrasonic sensor detects double feed,
the machine stops the operation. The double feed is
detected not by the paper thickness, but by the number
of sheets.

3 CCD Section
1. Description
This section reads the barcode and REG mark by
CCD.
2. Operation
On the JOB using REG mark or barcode, PPS2 works
to assure the correct CCD reading by temporarily
stopping the paper run at the place of PPS2 and slows
it. The paper conveyance speed will be accelerated
after the CCD reading.

3. Operation of Each Part
1. PPS2
<Operation>
•
PPS detects the presence or non-presence of paper
by the “light-through” or the “light-bloced” state of the
PPS photo-receiving sensor by means of
from the PPS photo-emitting sensor.
• In the operation without REG mark or barcode,
PPS2 detects the timing of passing paper.

Chapter 2 4 Margin Slitter Section
4 Margin Slitter Section
1. Description
The margin slitter is provided (slitter 1, 2) on both
sides to cut the paper along the traveling direction
by means of the rotary blades. The cut-off margin is
dropped into the waste box.
2. Operation
The lead screw is turned by means of the stepping
motor to cause the margin slitter to move from the
home position by the specifi ed amount of pulse.
3. Slitter Blade
The slitter blades are constructed so that the lower
blade of the slitter is tilted relative to the paper feed
direction. This makes the upper and lower slitter
blades contact at only one point to maintain the clean
cut even after the slitter blade has worn out.
4. Operation of Each Part
1. Margin Slitter Home Position Sensor
<Operation>
Margin slitter HP sensor detects the home position
of the margin slitter by the photo-micro sensor, and
controls the margin slitter position based on the
amount of pulse from the home position.
