10.4 CALIBRATIONS
10.4.1 Stencil Load Offset Position
The stencil load offset compensates for any tolerances of the print carriage position and/or the
stencil load paddle position which could result in the camera not looking at the stencil in correct
position in the Y axis.
NOTE
The camera reference position must be calibrated before the stencil load offset position can be set.
See Camera System Module chapter, Volume 2 for further details.
