2. Detection Mechanism
1) The set detection of the Master-making upper unit is detected by the Master-making unit safety
switch. When the Master-making upper unit is closed, the master set movement starts.
2) The master end detection is made by the Master end sensor detecting the black end-mark on the
master material at the end of the master roll.
When the Master end sensor detects the black marking on the master material, the machine
displays a panel message to inform the operator to replace the master roll.
3. Master Cutter Mechanism
1) The master cutting is done by a Cutter unit in which a Cutter blade disc slides on a rail.
2) Two switches are used to detect the position of the Cutter blade disc. One is the Cutter HP
switch and the other is the Cutter stop position switch. The Cutter blade disc rests at the HP
switch position. With the start of the master cutting operation, the Cutter motor slides the Cutter
blade disc to the other end of the Cutter unit and stops when the Cutter stop position switch is
activated by the Cutter blade disc. The Cutter blade disc then slides back to the HP switch with
the reverse rotation of the Cutter motor. The Cutter blade disc stops at the HP switch.
