of other individuals
Exposure to laser beams will cause severe burns.
Never aim the laser at yourself or at anyone else.
Do not touch workpieces during or just after marking
Workpieces may still be very hot.
Use only the specified cables. Make sure they are firmly
connected
Using cables of inadequate current capacity or connecting
cables loosely may result in fire or electric shock.
Avoid damaging power or connecting cables
Do not step on, twist, or pull cables.
Damaged cables may result in electric shock, short circuits, or
fires.
To repair or replace cables, contact your dealer or us.
Stop using the Laser Marker if any problems arise
Continuing to use the Laser Marker in the presence of
abnormalities (fumes, unusual sounds, excessive heat, smoke,
and so forth) may result in electric shock or fire.
In this case, immediately turn OFF the Laser Marker and
contact your dealer or us.
Ground the Laser Marker
Make sure that the Laser Marker is grounded before turning ON
the power supply. Failure to ground the Laser Marker may
result in electric shock.

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 required power supply is as follows: single-phase 100 V AC to 120 V AC (50/60 Hz)
with a capacity of at least 15 A, or 200 V AC to 240 V AC (50/60 Hz) with a capacity of at
least 7 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 (such 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 has
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.
•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 MAIN POWER switch of the Control Unit.
1.3 Guidelines for Normal Use

Chapter

11
ML-9011A
1.3 Guidelines for Normal Use
•If a computer is connected, never disconnect the LAN cable before turning off the MAIN 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.
•In the LD starting state, you will see green light even when the laser is not emitted. Since it is
classified Class 1 or lower, it does not have a safety problem, but do not directly look it in.
•When a supervisor or operator enters the area where the laser is used, safety measures not to
exceed the MPE* level must be provided.
* 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.
For other information on managing laser equipment or the MPE level, refer to the
following standards.
･JIS C 6802 "Safety of laser products"
･Ministry of Health, Labour and Welfare Notification No. 0325002 "Prevention
measures against laser injuries" (in Japanese)

Chapter 1Safety Precautions
●Turning the pumping diode on and off frequently will shorten its useful life.
Do not use the Emergency Stop switch to stop the unit unless it is an emergency. Use regular
methods.
●The useful life of pumping diodes is such that over time their output declines.
When the laser output declines from its initial level, increase the current. The current can be
increased up to the LD current limit (around 50%).
Refer to the manual for LMDraw6 for details.

ML-9011A
Overview of the
ML-9011A
The ML-9011A is an air-cooled second-harmonic generation (SHG) laser marker (532 nm) that uses a
diode laser (LD) for Nd:YVO4crystal excitation.
This marker produces wavelengths half the length of fundamental wavelengths (1064 nm), providing
marking spots of half the width for even greater marking precision. In addition to marking, the ML-9011A
can be used for highly detailed machining, including fine cutting work.
■YVO4 SHG Laser Marking
•Supports marking of highly reflective materials
The ML-9011A can mark highly reflective materials that cannot be marked with 1064 nm lasers.
Such materials include polyimide and other resins as well as copper, gold, and various other
metals.
•Single-mode marking
As single-mode lasers, YVO4laser markers focus beam energy into a single spot. For this and
other reasons, thermal efficiency surpasses conventional YAG lasers for reduced heat effects
outside the processing area.
•More stable at high frequencies
Nd:YVO4lasers are more stable at high frequencies, an advantage that affords exceptional
marking quality for materials commonly marked at high frequencies, such as resins.
■ML-9011A
•Compact and lightweight
Ideal for production lines where space is limited.
•Energy efficient
Low power consumption, thanks to a highly efficient diode laser.
•Fully air-cooled
Easy maintenance. Fully air-cooledno coolant or coolant filters needed.
•Compatible with PCs running Windows operating systems
The product is bundled with the LMDraw6 Windows-based marking application. Figures created
with commercial CAD software are easily registered as marking data.
•High-speed marking
Engraves 550 characters per second.
•Seven marking ranges
Choose the best marking range for the shape of your workpiece, in diameter of 80 mm, or areas
of 49 x 49 mm, 74 x 74 mm, 98 x 98 mm, 141 x 141 mm, 175 x 175 mm, or 216 x 216 mm. In the
digital scanner specification, diameter and area are slightly different.
•Large, easy-to-read screen for graphics
The Windows-based operating window provides a large, easy-to-see drawing area.
