Cover
A hardware safety switch is fitted at the rear of the cover. The software
safety switches are activated when the cover is closed. The printer can only
be used when the cover is closed. Opening the cover during a printing pro-
cess triggers an emergency stop.
Cleaning flap
On the front of the machine, below the cover, is a cleaning flap. The flap is
monitored by a safety switch. Opening the cleaning flap during a printing
process triggers an emergency stop.
Safety screen
A safety screen is fitted at the inlet to the printing table.
The safety screen is safeguarded by a hardware safety switch. It protects
the operator from reaching into the print area from the outside. If the safety
screen is moved, an emergency stop is triggered.
