This

ȱ
takes

20
ȱ
minutes,

and
ȱ
should

To clean the print heads and the roller:
1. Prepare—
•
isopropanol

Normal
Overheating
problem
If the UV lamp continues to overheat, and the temperature around the lamp
reaches 90 °C (194 °F), a heat fuse cuts the power to the UV lamp and the
motion motors. In the unlikely event that this occurs, the printer cannot be
used until it is serviced by an authorized service engineer.
