• On the fan fold unit, check that the main switch [1] and heater switch [2] are off.
1. Connect the fan fold unit power cord to the power source.
2. Look at the circuit breaker [3].
• With the horizontal line displayed on the circuit breaker, use the tip of a small screwdriver to
depress the breaker test button.
• The circuit breaker should flip to the "O" position. This indicates that the circuit breaker is operating
normally.
• If the circuit breaker does not flip to the "O" position, the circuit breaker must be replaced.
• Push the lever to display the vertical line again and reset the machine for normal operation.
• The fan fold unit will not switch on if the lever remains at the "O" position.
3. Disconnect the fan fold unit power cord from the power source.
Power On
The fan fold unit must be switched on before the main machine.
1. Switch on the fan fold unit.
2. Switch on the main machine.
• The fan fold unit must be switched on first, so that the main machine will recognize the fan fold unit
after the main machine is powered on and starts its initialization procedure.
Skew Adjustment
1. After setting up the system, do a folding test run with at least 10 sheets of A1 LEF paper.
• Before doing this procedure, measure the distances between the bridge unit and the left and
right rear corners of the main machine. The difference between these two distances must not be
more than 1 mm.
2. Measure the amount of skew.
• If the average amount of skew is less than ±0.5 mm, no adjustment is required.
• If the average amount of skew is more than ±0.5 mm, adjustment is required.
