16.6 CALIBRATIONS
NOTE
Where the printer is connected to inline equipment make sure that the FMI functionality is turned
OFF before proceeding.
The front and rear board transport belts are driven independently by two variable speed motors. In-
evitably one motor drives faster than the other motor. It is necessary to calibrate these motors so
that they drive at the same speed.
Feeder motor speed is measured using a tachometer on the input or output pulley and adjusted by
a potentiometer control on each motor.
