(6) The print drum pauses at the 220°
position, where the master is cut.
(7) After the print drum has rotated a further
15°, the Master positioning sensor
confirms that the master has been cut.
Cutting has been performed correctly if the
light path to the sensor is blocked (no
master).
If the light path to the sensor is open, it is
determined that an error has occurred.
In this case, the cutting operation is
repeated, the Master positioning sensor
confirms whether the master has been cut
after the print drum has rotated a further
15°. If it is cut, "A03 Cutting error" is
displayed, and if it is not cut, "T13 Cutter
motor lock" is displayed.
(8) The master setting operation is performed.
