CHAPTER 14. MASTER MAKING SECTION
6. Master Cutting Mechanism
Cutter Mechanism
The master is cut by the rotary cutter on the cutter unit, which is rotated by the cutter motor.
The cutter motor rotates in one direction only.
The position of the rotary cutter is confirmed by the cutter home position switch. The home position
for the cutter is the point at which the switch is raised.
Master Cutting
The master cutting starts when the print drum is at the 298.8° position.
The print drum rotates during master cutting.
The switch is depressed after the cutter motor starts rotating, and the motor stops again when the
switch is no longer depressed.
Initialization Movement
The cutter is initialized when the power is switched on, during “All Reset”, and when master making
begins.
Initialization is not performed if the cutter is at the home position (cutter home position switch is not
depressed) at the start of the operation.
If the cutter home position switch is depressed, the cutter motor rotates until the switch is no longer
depressed.
