CHAPTER 10: MASTER REMOVAL SECTION
[ 10 - 4 ]
3. Removed Master Vertical Transport Mechanism
At the start of the clamp plate opening action to remove the master from the drum, the master removal motor
activates to rotate the master removal rollers to catch the leading edge of the removed master from the drum.
With the continued rotation of the print drum, the removed master is transferred into the master disposal box by
the master removal rollers.
Once the master removal action has started and the print drum rotates to position-A, the main motor stops,
and also the master removal motor deactivates 0.5 seconds later.
Whether the master has arrived into the master disposal area or not is checked by the master removal sensor
at drum angles 120 degrees and 180 degrees during the master removal action.
The master removal roller speed is checked by the master removal motor FG sensor, and the speed can be
adjusted by test mode No. 578.
After the master removal action ends, the master-guiding-plates A and B are raised by the master compression
plate to clear the path for the oncoming master on the next master removal action.
