CHAPTER 10. MASTER REMOVAL SECTION

REMOVED MASTER VERTICAL TRANSPORT MECHANISM

3. Removed Master Vertical Transport Mechanism
When the clamp unit is operated to release the leading edge of the master from the clamp plate, the
Master removal motor [A] activates, rotating the Vertical transport rollers [B, C, D, E, F]. The main motor
also rotates the print drum at the same time.
The master is fed between the rollers and pushed into the Master compression plate [H].
The master is guided here by the Master removal hook [G] and G belt [J].
The main motor and Master removal motor [A] stop once the print drum has rotated to position-A. (The
time at which the master removal motor stops can be adjusted using test mode No. 382.)
When the print drum reaches the 70° and 90° positions, the Master removal sensor [I] checks whether the
master is being fed correctly to the master disposal box. (These drum angles can be adjusted using test
modes No. 380 and 381.)
The master removal hook is normally located at a fixed position close to the print drum, but shifts away
from the drum when the drum is pulled out.
The print drum rotation speed during master removal can be adjusted using test mode No. 387.
