Platemaking / Master Feed / Ejection Section
chap.2
When the drum stops at the plate detachment position and the master clamp which clamps the master tip end
is opened (C mode), the pulling roller on the rolling section of the master ejection box pulls the master tip end
into the box inside, and the master is rolled up to the core.
If no core is installed, or when the master is fully wound onto the core, the ejection box full switch (MS8) is
mechanically actuated, and the message
"CHANGE MASTER EJECTION CORE"
appears on the LCD panel.
