UV Lamp Check
A heat-sensitive label is fixed to the UV lamp covers as a warning against
overheating. Its center changes from white to black if the temperature of the
cover reaches 65°C (150°F). If this occurs, do not use the printer, and call your
service provider. As a precaution, it is recommended that you check the label
before and after printing.

If the UV lamp continues to overheat, and the temperature around the lamp
reaches 90°C (194°F), a heat fuse turns off the electricity to the power to the
UV lamp and the motors for the X, Y, and Z axes. In the unlikely event that this
occurs, the printer cannot be used until it is serviced by an authorized service
engineer.
Pattern Test
The pattern test is the basic verification of the printer’s ability to produce quality
models, since it demonstrates the condition of the nozzles in the print heads.
Make sure, therefore, that you perform this test weekly, and whenever you
suspect a printing problem.
To perform the pattern test:
1. Make sure that the build tray is empty.
2. Prepare a sheet of pink paper, A-4 or Letter size.
3. In the printer, tape the pink paper to the surface left of the build tray.
4. Press

, or open the
