MASTER ON THE DRUM (BEFORE MASTER REMOVAL) CHECK MECHANISM

2. Master on the Drum (before Master Removal) Check Mecha-
nism
When creating confidential or normal masters, the print drum moves to position A, and with the print drum
at the 75° position, the Master sensor [A] checks whether or not there is a master [B] on the drum. (The
check operation is not performed if information that a master is present has already been stored in the
machine's memory.) The drum rotation angle for the check can be adjusted using test mode No. 580.
If the light from the Master sensor [B] is reflected back, (master present), the master removal sensor
checks whether the master is sent to the master disposal box or not during the master removal.
A: Master sensor
B: Master
C: Light absorber strip
