6.3.6 Automatic Laser Power Calibration
A. Requirements
PERFORMED BY
End user (reserved for
user level Engineer)
B. Protective personnel equipment
WARNING: MAKE SURE ALL SAFETY PRECAUTIONS ARE FOLLOWED AS SPECIFIED IN THE USER GUIDES AND IN
THE SERVICE TRAINING PROGRAM.
WARNING: ALWAYS BE AWARE OF THE RISKS INVOLVED WITH LASER RADIATION. MAKE SURE THE LASER IS
TURNED OFF WHEN THE PRINTER DOOR IS OPEN.
C. Procedure
This procedure describes how to perform an automatic laser power calibration on the DMP Flex/Factory 350 systems.
Make sure the machine is clean of all powder before starting.
1. Preparation: Lock the printing module in place using the 2 locking handles. Cover the powder feed platforms and clean the
laser window using the appropriate materials as indicated in the 15-D98 - DMP Factory 350 - User Guide.
2. Place the laser power sensor on top of a holder. The
bottom of the sensor should be free to provide fresh air to
the cooling system. The sides of the sensor should be free
as well so that hot air can be removed from the cooling
system. The device should be flat and stable. The sensor
should be high enough so it is out of focus
3. Plug the sensor into an electrical socket of the facility to
provide the 220V AC required for the fan cooling of the
laser power sensor.
4. Connect the sensor to the computer through one of the
USB ports on the front control panel.
