Explanation of Conditional Change

Implement this FCO in cases where the electrostatic discharge is needed in the film path.

FCO Kit part no. : 510F19290
Effective on machines with S/N lower then 9430XXXX

Reason for Change

Sometimes electrostatic discharge is needed in the film path. The film is attached to the drum during loading and that can cause registration problems.  The film can get stuck during unload due to the electrostatic.

Description of Change

Electrostatic discharge brushes have been added in four places in the loading and unloading path.   

Change Procedure

1. Turn off the plotter.
   
   
2. Pull out the loading system.
   
   
3. Remove the CLAMP from the loading system by releasing the two shaft clamp housings (4 screws) and the two springs.
   
   
4. Remove the two clamp-CAM from both sides of the clamp.   
   
   
5. File the anodize coating from the clamp in the places where the brush will be glued (10 places 20mm each).           
   
   
6. Attach the brush to the clamp according to the enclosed figure.
   
   
7. Reinstall the two clamp-CAMs.
   
   
8. Cut out the brush from the edges.

10. Remove the unloading film guide from the loading system.
    
    
11. Attach the brush to the guide.
    
    
12. Reinstall the unloading film guide and make sure that the brush is attached to the cutter base.
    
    
13. Cut out the brush from the edges.
    
    
14. Remove the funnel from the plotter.
    
    
15. Attach the brush on the selecting cover and secure it with the caterpillar. Press on the caterpillar in order to secure the brush.
    
    
16. Glue the caterpillar edges using the adhesive rapid cure glue.
    
    
17. Remove the selector film guide base from the funnel.
    
    
18. File the anodize coating from the base in the places where the brush will be glued (10 places 20mm each).
    
    
19. Attach the brush to the base.
20. Install the selector base and the funnel into the plotter.   

Test Procedure

Load and unload film and make sure that no electrostatic problems appear.                                
In case of film crash ("S" effect) then:

• If the current S/W version is bellow 5.0:
  upgrade the imagesetter to ver. 4.08. This will cause the roller to move back and forth during film loading.
• If the current S/W version is 5.0 or above:
  Refer to version 5.0 release document.
