6.5.12 CUTTER MECHANISM
[A]: Cutter motor
[B]: Cutter HP sensor
•
When the cutter starts, the drum is stopped at the master eject position (drum
HP).
•
The cutter moves backwards and forwards. While the cutter travels towards the
rear (non-operation side), it cuts the master. The motor turns in one direction.
The cutter returns to the home position when it reaches the rear because of the
two different spiral threads on the screw shaft.
•
The cutter usually cuts a master of about 550 mm in length. The cutter cuts a
master of about 340 mm in length when an optional A4 black drum is used.
•
After cutting, the drum starts turning again to wrap the remaining part of the
master around the drum. The leading edge of the master that was cut remains at
the cutting position, ready to make the next master.
6.5.13 RE-CUTTING MECHANISM
•
If the CPU cannot detect the master eject position sensor (drum HP) signal within
5.0 seconds after the main motor turns on at the start of master making, this
could be because of an error in master cutting.
•
So the cutter tries to cut the master again. If the CPU still cannot detect a signal
from the master eject position sensor when the main motor starts again, E-06
(Main Motor error) occurs.
