6.3 Calibration

compressed and not cover the lower position of the paper. If the value is too large the printout
will continue below the paper, loosing the last braille lines.
It is recommended to make a paper calibration:
When the electronic main board is replaced.
When the paper quality is significantly changed.
When the braille print out area does not fit to the paper size after making sure the same paper
size is used as the one setup in the embosser menu.
