Magnus 800 platesetter

Background

The drum vacuum holes invariably fill up with debris and dirt. In order for the vacuum to be effective, it is essential that the holes remain unblocked and dirt-free.
This procedure describes how to clean the drum vacuum holes.

Requirements

Drum Holes kit (part number 690-00127A)

Procedure

1. In Magnus Controller, click Raise Platform to raise the loading platform:
   
   
   
   
2. Remove the upper front panel:
   
   
   
   
3. Manually rotate the drum until the first set of vacuum holes, immediately after the LEC, is visible.
4. The Drum Holes kit (part number 690-00127A) contains two
   0.8-mm wire bits, and two 0.8-mm drill bits. Insert one of the 0.8-mm wire bits into the cleaning jig.
5. Starting from the first set of holes, located immediately after the LEC, systematically insert the cleaning jig into each drum vacuum hole. (Make sure the jig is long enough to reach the bottom of the drum vaccum hole.) Repeatedly prod the vacuum holes until they are dirt free and unblocked.
   Note: For badly blocked holes, replace the wire bit with the 0.8-mm drill bit.
   
   
   
   
6. Reinstall the upper front panel.
7. Manually close the loading platform.

Test

1. In Magnus Controller, make sure the platesetter status indicator appears as Ready.
2. On the platesetter, make sure the status light is green.
3. Expose the customer’s largest plate format at 50% tint (plot 50 in Service Shell), and make sure that neither hot spots or attachments appear on the image.
