When ON: Master positioning sensor: Open, Master detection sensor: Open, Master end sensor: Blocked
The master positioning operation starts after master cutting is complete when setting the master loading
unit and master creation.
(1) The master detection sensor detects whether a master is present on starting. If the master detection
sensor is OFF, error message [D05-210] is displayed.
(2) The master end sensor is checked at 10 ms intervals, and if an end mark is detected twice in
succession, error message [C02-200] is displayed.
(3) The write pulse motor and load pulse motor operate in the feed direction until the master positioning
sensor goes ON. A time-out occurs here when it has fed 75 mm when setting the master loading
unit and 25 mm when inching after cutting, and error message [A01-201] is displayed.
(4) The write pulse motor and load pulse motor operate in the return direction until the master
positioning sensor goes OFF. A time-out occurs here when it has fed B mm, and error message
[A01-202] is displayed. (B = 3 mm + value set in Test mode No. 280)
(5) The master is moved a further B mm in the return direction after the master positioning sensor goes
OFF, and then motor then stops, ending the master positioning operation.
