Mirrored Image
When the scan engine is mounted upside down, the sensor data needs to be rotated 180º. This
configuration is especially necessary for image acquisition and OCR reading.
When an external mirror is installed in front of the scan engine, the scan engine should mirror
the sensor data. The scan engine can mirror the sensor data horizontally or vertically.
