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.

● The cutter unit, slitter unit, and perforation unit contain sharp tools (blades) which may

cause danger. Exercise great care when inspecting these units or replacing them or
their parts.

→ Otherwise, your hands/fi ngers could get caught and injured.

● Do not put your hands or fi ngers inside the machine while it is operating and while

you are pressing the JOG key.

→ Otherwise, your hands/fi ngers could get caught and injured.
In addition, when you remove paper clogged up or work on the machine, be very careful not
to roll up a tie and/or a necklace by the machine.

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

<Operation>

As the feed tray goes up, the angle is pulled away
from the elevator lower limit switch to come to 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.

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. Description

The “Guillotine type” cutter module is provided in
which the lower blade is fi xed while the upper blade
moves up and down to cut the paper perpendicularly
to the traveling direction.

2. Operation

The rotating motion of the DC motor is transformed
into the reciprocating motion of the upper blade by
means of the eccentric shaft.
A sensor is provided at the top dead center of the
blade stroke, which works to apply the brake on the
blade movement at every reciprocating cycle to make
it stop.

1. Description

Creaser module contains the lower blade having
a concave (recessed) section and the upper blade
having a convex (projected) section. The creaser
unit works to crease the paper perpendicularly to its
traveling direction.

2. Operation

The sensor plate provided coaxially with the cam
detects the top dead center of the upper blade to
control the DC motor. The lower blade also can
move up and down by a cam. The height of the
lower blade is set by the DC motor with an encoder,
and is specifi ed relative to the lower blade’s bottom
dead center at which the sensor plate is provided.
The crease depth is determined in this way.

CAUTION

•Always remove the power cord plug from the outlet before starting work.

•Cautions Regarding Disassembly and Assembly

•In principle, do not operate this machine with parts removed.

•When assembling:

•Unless specifi ed otherwise, perform the disassembly procedure in reverse.

•Make sure that screw types (radius, length) and locations are correct.

•Be sure to use rosette washers when they are specifi ed.
(Rosette washers are used with installation screws to prevent static electricity.)

•To ensure electrical current, a rosette washer is used with the installation screw on
the ground wire. Be sure to use the rosette washer during assembly.
