Electrostatic Discharges, and Earth Currents
Preventing ESD and earth currents from affecting the printer operation requires proper
connection of the printer chassis to protective earth through a mounting platform or through a
separate earth conductor. The signal ground is not connected to protective earth (chassis)
inside the printer.
. Fasten an earth cable to the printer using an M4x6 screw. Always put a lock
washer between the chassis and the connector.

Ambient Light
There are optical sensors just inside the paper exit at the front of the printer.
To ensure proper printer operation, design the printer enclosure so that it prevents direct
sunlight or light from indoor lamps from reaching the sensor through the paper exit.
