ERROR IN Y-AXIS POSITION
Cause:
The motor driving the machine head cannot move to the position wanted. This is a fatal error.
It can only be solved by turning the power off and then on again. This error is usually caused
by a media crash.
Action:
14.Remove the crashed media and restart the machine.
15.Lower the speed and/or the knife pressure.
16.Check whether the head moves smoothly (first turn the power off and position the cam
rollers on the outer edges of the media).
17.Check the y-axis motor and the encoder cables.
18.Replace the Y-motor.
19.Replace the PCB.
LOW LINE VOLTAGE
Cause:
The secondary voltage of the transformer is measured by the µP on the PCB. When it
measures a value lower than the lower limit setting, the machine will give this error. This is a
fatal error. Switching the power off and making a corrective action is the only solution.
Action:
20.Measure the line voltage. Check whether the voltage selector at the back of the machine
is set to the correct line voltage. The line voltage should be between the selected
v8% or -10%.
21.Check the secondary voltage of the transformer. It should be at least 22VAC. If that is not
the case, replace the transformer.
22.Check the DC power on the PCB (on the power cable going to the machine interface
board). It should be at least 27VDC.
23.Disconnect the motor cables, the encoder cables, the flat cable going to the head, the fan
cable, the sensor cables and the 28V power cable going to the machine interface
board, and switch the machine on again.
24.When you have done this, plug in the cables one by one until the energy consumer is
found. Replace it.
25.Replace the main PCB.
