Master On The Drum Check Mechanism (Before Master Removal) - Riso RZ3xx Series Technical Manual

2. Master on the Drum Check Mechanism (Before Master Removal)

When creating a confidential or normal master, the print drum makes one rotation from its position-B. During
this rotation, the Master sensor checks for the presence of the master on the drum at 40 degrees turn from
position-A. If a master is found on the drum, the machine makes the master removal action with the master
removal sensor active. If no master is found, the master removal action is made with the master removal
sensor deactivated.
The default position of 40 degrees from position-A to check the presence of master on the drum can be
changed by test mode No. 940.
If the machine already knows that there is a master on the drum before going into master making operation,
the master on the drum check action is skipped, and the print drum starting the rotation from the position-B
goes immediately into master removal action.
