Background

This procedure describes how to calibrate the plate length detector on the Magnus 400 platesetter.

Procedure

To calibrate the plate length detector:

1. Before loading a plate, in the Registry Editor, change the Plate Length Tolerance (mm) parameter from 5 (default) to 50.
   HKEY_LOCAL_MACHINE\SOFTWARE\Scitex\Projects\LOTEM400V\IO OBJECTS\Loading System\Load Plate\From Drum entry to Drum Stage
2. Open the Log dialog box and select Debug.
   
   
   
   
3. In the Loading System dialog box, select the plate size to load, and then load a plate.
   The message Expect plate size [mm], Actual Plate size [mm], and the differences between them [error on measurement] appears in the log, indicating the next numbers.
4. Copy the differences value and add it to the Length from Head Gripper to Right PresetDet (mm) parameter (default = 135).
   HKEY_LOCAL_MACHINE\SOFTWARE\Scitex\Projects\LOTEM400V\IO OBJECTS\Loading System\Load Plate\From Drum entry to Drum Stage
5. Return the Plate Length Tolerance (mm) parameter to the default value (5).
6. Test the accuracy of the plate measurement by loading each plate size several times.

To test and adjust plate measurement accuracy after calibrating the plate length detector:

1. Load each plate size several times.
2. Check the image quality and change the registry parameters, if required.
   • Load Plate Extra to Drum (default = 17)
   • Load Plate to Drum Position (default = 96.5)
