Installation Considerations

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.

See Figure 6. 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.
