When controlling the printer via a remote PC, The 'Select
input tray' screen is preceded by a screen, which allows you
to:
• Start the quality control procedure immediately,
• Edit additional data for the last quality control
measuring.

WARNING:
Good viewing conditions are important for the correct
interpretation of both diagnostic and test images. Make sure
that the light box intensity (luminance) is between 2000 and
4000 cd/m² (4500 and 6500 °K) for general radiography. Use a
magnifying glass and use shutters to collimate. Make sure the
ambient light is low.
