The module height influences the recognition rate of the symbol.
The module height is recommended to be set to 3-5 times the module width.
The recognition rate might decrease when the vertical size of the symbol is 5 mm {0.2"} or less.
The vertical size of the symbol can be confirmed by the transmission data of Function 082.
