Before replacing the strip module, check
• that the sensor is in its horizontal position,
• that nothing blocks the LED and the sensor, for example dust or stuck
labels,
• that the back side of the media is able to refl ect the light,
• and that the cables of the sensor are visibly undamaged and properly
connected to CN12 on the main board.
Replace the strip module this way:

The electronics compartment contains high voltages wires and circuitry.
