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.
Ambient Light
There is an optical sensor 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.
