Loading /Unloading

Panel opening is not allowed during load/unload.
 
Load procedure Basic semi-automatic
  1. Off line punching.
  2. Positioning plate on loading tray.
  3. Machine automatically loads plate onto drum.
  Option – full auto, multi cassette loading Fully automatic operation.
  1. Plate loading from 3 trays.
  2. Interleaf paper removal.
  3. Punching.
  4. Machine automatically loads plate onto drum.
Unload procedure   Auto unloading of plates.
In-line conveyor   Optional, supplied by Scitex

Punch - Image to Edge

Semi-auto config.   No punching. Image positioning is by plate edge detection.
Basic definition This option will meet customer needs only in auto-loading version. Punches will be field added option, and payable based on configuration. Platesetter will be manufactured and supplied with no punches. Standard punch kits will be defined based on press configurations. Punches will be selectable, so that the image area of any selected plate, within the spec range will not be punched by undesired holes. Maximum 5 punches.
Location    Leading edge of plate (relative to press loading direction).
