If calibration does not end successfully, the faulty photosensor is identified through specific LED
configurations. Pressing one of the console buttons allows you to identify any other faulty photosensor.
In this case, the other calibrations or measurements may not be performed. If, instead, calibration was
successful, load an A4 sheet of paper in order to print the calibration values. The following table
indicates the parameters that need to be checked.

Perform a further check by inserting a form with a check format code 152136J at the two sides and
center of the insertion slot and with its shortest side parallel to the axis of the photosensors. Check for
correct operation.
Note: The parameters indicated above are useful indications to determine in which operating segment
the PR2 E is positioned as far as document acceptance is concerned.
