Chapter 1Safety Precautions
•Appoint a safety supervisor with as much expertise and experience with lasers and laser equipment
as possible. The supervisor, who will be in charge of the laser key switch, should familiarize users
with safety issues and coordinate laser marking.
•Partition off the area which might be exposed to the laser beam. A supervisor should control this work
area and post signs to keep out unauthorized personnel.
•Install the Laser Marker on a solid, level surface. Using the unit (other than the Head Unit) at an angle
or on its side may damage it.
- To prevent distorted marking, put workpieces on the same stand as the Head Unit so that
the workpieces do not vibrate during marking.
- The power supply must be single-phase 100 V AC to 240 V AC, with capacity of at least 10
A.
- Be sure to ground the unit with a Class D ground.
•To ensure optimal marking quality, use the Laser Marker in a place where the ambient temperature is
5 to 35 °C, where the relative humidity is 40 to 80%, and where it is not subject to sudden
temperature fluctuations. In addition, do not use the marker in the following places:
- Where there is excessive dirt, dust, or oil mist
- Where the unit is subject to vibration or impact
- Where the unit is exposed to chemicals
- Where there is a nearby source of high noise
- Where moisture may condense on the unit
•If the room temperature changes quickly (as when a heater is turned on in cold weather), moisture
may condense on the optical elements. Dust may adhere or the elements may become fogged up
with condensation. Thus, avoid sudden temperature changes. If condensation may have occurred,
wait for a while after turning the unit on before starting operation.
•The exterior of the system should be wiped clean using a soft or moist cloth. If the exterior is
particularly dirty, wipe it clean using diluted detergent or alcohol.
Do not use paint thinner, benzine, or similar chemicals, which may discolor the unit or deform parts.
•Do not place screws or other foreign objects inside the marker. This may damage the unit.
•Operate the switches and buttons gently by hand. Applying excessive force or using the tip of a
screwdriver, a pen, or other instrument may damage or break the switches or buttons.
•Operate only one switch or button at a time. Operating several switches or buttons at a time may
damage or break the unit.
•Do not turn off the power switch while a computer is connected to the Control Unit.
•If a computer is connected, it will continue to access the memory card for about 15 seconds after
going offline. During this time, do not turn off the power switch of the Control Unit.
1.3 Guidelines for Normal Use

Chapter
1
11
ML-73 □□ EL
1.3 Guidelines for Normal Use
•If a computer is connected, never disconnect the USB cable before turning off the power switch.
•For more consistent marking, allow the unit to warm up for about 10 to 30 minutes after turning on the
LD. The warmup time varies depending on the temperature and workpiece material.
•Use only memory cards purchased from us. If commercial cards are used, the unit may not function
normally.
•Before inserting or removing memory cards, always turn off the power switch. If the power switch is
on when cards are inserted or removed, data may be lost or the memory card may become unusable.
•Back up memory card data regularly.
If the memory card data becomes corrupted, it may prevent normal marking or the marker may not
start.
•The memory card connector can withstand 10,000 insertion/removal cycles, according to values
published by the connector manufacturer.
•When a supervisor or operator enters the area where the laser is used, protective measures not to
exceed the MPE* level must be taken.
* MPE: The maximum level of permissible exposure of the eyes or skin to laser beams. Abbreviation
of Maximum Permissible Exposure.
•Since the surge absorber is built in, do not perform the insulation resistance test and the withstand
voltage test. If the surge absorber fails, the marker may become unusable.
•The ML-73□3EL head unit has IP64 dust- and splash-proof performance. The performance can be
provided only by installing the control cable, fθ lens (f420, f508, f100 (telecentric), and f163
(telecentric) are not compatible) and protective glass properly.
•The water and oil proof head unit (option) has IP67 dust- and water-proof performance and IPXXG (in
the JIS standard) oil-proof performance. The performance can be provided only by installing the
control cable, fθ lens and protective glass properly. The head has a protective structure, but it cannot
be used in water or oil.
•Capable of corresponding to the fully closed locker to enhance the environment resistance of the
control unit. (This is not compatible with IP67G.) For details, contact us.

2.1 Features
•Supports registration of multiple marking conditions
Up to 1,023 conditions may be specified.
•Auto backup
Specify an interval (in time or number of operations) for automatic data backup.
•Dust-proof head
The ML-73□0EL standard head is IP5X compatible. The ML-73□3EL standard head is IP64
compatible.
•Water and oil proof head (ML-73□0EL option)
The optional head is IP67 and IPXXG (the JIS standard) compatible.
•Fully closed locker for control unit (option)
Capable of corresponding to the fully closed locker to enhance the environment resistance of the
control unit. (This is not compatible with IP67G.)
•High-repetition frequency
High-speed, contrasty, and clear marking can be achieved with 20 k to 200 kHz (ML-732□EL) of
repetition frequency.
•Built-in power monitor (ML-73□3EL)
- Controlling the laser power of each workpiece prevents the outflow of defective. (RS-232C
communication)
- Power values can be logged at the set time. (RS-232C communication)
- Variation from device to device can be corrected by calibration by external power meter.
・Coaxial camera mountable (ML-73□3EL)
Since the C-mount camera can be mounted coaxially with the laser beam, it can be used for
positioning a small workpiece. By combining the coaxial camera and image processing, auto-
matic position correction can be achieved.
・Fully digital scanner equipped (ML-73□3EL)
High-repetition position accuracy and low drift are achieved, which are difficult to be achieved by
an analog scanner.
・Various optical composition (ML-73□3EL)
The most suitable optical composition for your purpose can be selected from among 8-type fθ
lens and 3-type expander lens.
