● The printing scan count maximum value is dependent on the printed character width
and conveyor maximum speed and calculated using the following equation.
Substitute the nozzle diameter suited for the model you are using for item d.

● Using Equation 2, check whether the printing scan count maximum value
determined by Equation 1 can be followed by the IJ printer printing speed.
