INTRODUCTION
6 AREX™ 401
OVERVIEW
The Fiber laser marker developed and manufactured by Datalogic employs the most
advanced technologies with regards to the opto-mechanical parts, the electronic con-
trol of laser beam power, communication and the overall safety of the entire marker.
The Arex™ 401 laser marker features a control rack and a scan head. The control rack
size is standard 19" 3.5U. The scan head compact dimensions make it easy to integrate.
All product connections are on the rear or front of the control rack.
Laser Source
On Arex™ 401 laser marker it is used a sealed fiber laser source. This source is based on
the new fiber solid state technology. It guaranties high stability, lower sensitivity to opti-
cal misalignment and a longer product lifetime.
Galvanometric scan head
The scan head features two deflection mirrors that deflect the beam in X and Y direc-
tions, depending on the graphics/pattern to be reproduced.
Operation of a laser marker with galvanometric scanning
During the marking the laser generates an invisible, high-energy infrared beam.
In order to obtain a more accurate focus, the laser beam is first enlarged using an optical
expansion system and then deflected by a scanning system consisting of two mirrors
mounted on galvanometric motors.
These mirrors deflect the beam in a controlled path along the X and Y axes; processing
of the product surface occurs by coordinating the movement of the two mirrors and the
turning on/off of the laser beam.
The deflected laser beam is focused by an F-Theta scan lens on the surface of the prod-
uct.
Generally speaking, the marking is carried out within the focus plane of the F-Theta scan
lens.
Marking Software
The Lighter™ marking software is preinstalled on the product.
NOTE: Consult Lighter™ software user's manual for a proper use of the
same.
NOTE: If necessary, consult “How to update the marking software” on
page 121, to upgrade the preinstalled software.
CAUTION: Arex™ 401 is compatible only with Lighter Suite 7.4.3 and fol-
lowing.

ON MOISTURE CONDENSATION
USER MANUAL 11
ON MOISTURE CONDENSATION
If the laser marker is brought directly from a cold to a warm location, moisture may con-
dense inside or outside the laser product. This moisture condensation may cause a mal-
function of the laser marker.
Note on moisture condensation
Moisture may condense when you bring the laser marker from a cold place into a warm
place (or vice versa) and when you use the laser marker in a humid place.
If moisture condensation occurs
Turn off the laser marker and wait about 1 hour for the moisture to evaporate.
How to avoid moisture condensation
Before moving the laser marker from a cold place into a warm place, put it in a plastic
bag and seal it tightly. Remove the bag when the air temperature inside the plastic bag
has reached the ambient temperature (after about 1 hour).
