¡
When the rotary encoder is used, you cannot change the IJ printer character width. If it
is necessary to change the character width, you have to install an appropriate device
that will permit you to vary the ratio between the conveyor speed and rotary encoder
speed synchronization signal pulse count.
¡
The number of speed synchronization signal pulses from the rotary encoder is
dependent on the printing scan count and pulse rate division factor and calculated using
the following equation.
Number of speed synchronization signal pulses[kHz]
=
……
(Equation 3)
The pulse rate division factor (l/n) must be set up from the print specifications screen.
(See Section 3.4, Setting Character Height and Character Orientation).
¡
If the calculation result derived from Equation 2 is smaller than the printing scan count
maximum value (Equation 1), the product speed matching feature does not work
normally so that the character width is increased. In such an instance, lower the
conveyor maximum speed as needed so that the printing scan count maximum value is
smaller than the calculation result of Equation 2.
