Overview of the ML-7111A

8ML-7 Series/ML-9001A
Overview of the
ML-7111A
The ML-7111A is a scanning diode laser (LD)-pumped YVO4laser marker. This marker offers the
following features:
■YVO4Laser Marking
•Permanent marking
In contrast to ink-based printing, laser marking is permanent, since the laser beam changes the
material itself.
•Environmentally friendly
No solvent is needed, since no ink is used. Use of recycling marked materials is easier because
they contain no ink.
•Supports fine letters and detailed pictures
Laser marking makes it easy to make even highly detailed markings. Perfect for marking on tiny
electronic components.
•Non-contact marking
Permits marking of curved and concave surfaces.
■ML-7111A
•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-cooled-no coolant or coolant filters needed.
•Compatible with PCs running Windows operating systems (when a computer is connected)
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 350 characters per second.
•Built-in guide beam
A red guide beam for positioning makes it easy to align marking positions.
•Seven marking ranges
Choose the best marking range for the shape of your workpiece, in diameters of 39 mm, 80 mm,
120 mm, or 216 mm, or areas of 100 x100 mm, 150 x150 mm, or 294 x 294 mm.
•Large, easy-to-read screen for graphics
The Windows-based operating window provides a large, easy-to-see drawing area.
•Improved usability
The basic screen for normal use consists of just two main screens for drawing and marker
operations for a simple working environment.

For loading and saving marking data.
Insert a memory card to prepare the marker for use.
cAccess Indicator
Remains lit during memory card access.
dControl Key Switch
Turn the key switch ON to prepare the LD.
Turn OFF to deactivate the LD.
eEmergency Stop Button
Press to halt operations in emergencies. This will immediately suspend marking and turn OFF the
LD.
Once pressed, the button will remain depressed. To reset this button, turn in the direction indicated
by the arrows.
fPanel Indicators
Panel indicators light in accordance with the status of the unit as follows:
*1 All indicators are lit during self-diagnostics, starting with POWER.
(Refer to the Operating Unit manual.)
*2 READY blinks during LD cooldown after the LD is turned OFF.
(Refer to the Operating Unit manual.)
Always turn OFF the main switch before inserting or removing memory cards.
If the main switch is on when cards are inserted or removed, data may be lost or the
memory card may be rendered unusable.
We recommend backing up your data at periodic intervals to prevent data loss.
(Refer to the Installation/Maintenance manual.)
Use only the specified memory cards.
Use of non-specified commercial cards may result in aberrant function.
Do not turn OFF the main switch when the Access indicator is lit.
Turning OFF the main switch when the indicator is lit may result in data loss or
unreadable memory cards.
Frequent use of the emergency stop button will significantly affect the LD service life.
Use this button to stop the device only in emergency situations.
POWER*1 The unit is ON.
READY*1*2 The LD is ON.
SHUTTER*1 The Safety Shutter in the Head Unit is open.
MARKING*1 Marking underway
GUIDE*1 The guide beam is ON.
TROUBLE*1 An error occurred.

Insert the supplied connector if you do not intend to control the unit from an external device.
bExtended I/O Control Connector (D-Sub 15-Pin, Female) (Option)
Extended connector for I/O signals for unit control from an external device.
Used, for example, to select a Start No. from the external device.
cOperating Unit Connector
For communications with the Operating Unit.
If you do not plan to use this option, leave the unit as it was delivered (with the connector inserted).
If the indicators light up in sequence from READY to TROUBLE, the unit has detected
a sudden power outage or voltage drop. Turn OFF the main switch and check the
power supply and voltage.
