Belt Speed
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. Inevitably, 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.
1. Remove the right hand safety cover to gain access to the transport belt
motors.
2. Select Maintenance.
3. Select Diagnostics.
4. Use Next or Previous to highlight Rail System.

10. Using a tachometer fitted with the surface speed test wheel, positioned on
the input or output pulley of the front belt motor, measure the speed of the
motor left to right.
11. Ensure that a speed of 29 to 31 m/min is achieved.
12. Repeat steps 10 and 11 for Front R 2 L Speed, Rear L 2 R Speed and Rear
R 2 L Speed.
13. In the table highlight Front L 2 R ALT Speed.
14. Using a tachometer fitted with the surface speed test wheel, positioned on
the input or output pulley of the front belt motor, measure the speed of the
motor left to right.
15. Select Incr. or Decr. to adjust the motor speed to achieve 14 to 16 m/min.
16. Repeat steps 14 and 15 for Front R 2 L ALT Speed, Rear L 2 R ALT Speed

17. If adjustment is required, remove the belt speed adjuster cap on the appropi-
ate motor and adjust using a suitable trimming tool.
18. Select Next.
19. Select Incr. or Decr. to start the belts running left to right.
20. Ensure that a speed of 29 to 31 m/min is achieved for both the front and
rear belts.
NOTE
