6.8.3 Interpretation of the results obtained
‘DP rotation angle’ error for all segments
Cause Solution
Possible contamination of component camera ► Clean the lens or replace the component
camera.
‘DP rotation angle’ error for individual segments
Cause Solution
DP does not rotate reliably ► Replace the segment (DP).
Calibration component rotates on nozzle ► Check if the nozzle is dirty and clean it if
necessary.
► Check the nozzle seat.
► Check the vacuum supply.

6.9 Dp- / Z-Positioning
6.9.1 Measurement principle
The Dp-/Z-Positioning measurement checks the deviation between the Z-axis down light barrier
and the component sensor, in accordance with the angle setting of the segment. Each segment is
moved down and moved to an angle of 0°, 60°, 120°, 180°, 240° and 300°. For each angle, the
position is determined where the nozzle interrupts the beam of the component sensor and when
the light barrier is activated.

6.9.3 Interpretation of the results obtained
‘ZVariation’ and ‘CSVariation’ error for all segments
Cause Solution
Mechanical damage to Z-axis linear guide ► Replace the Z-axis drive.
Z-axis read unit dirty ► Clean the Z-axis read unit.
‘ZVariation’ error for individual segments
Cause Solution
Mechanical damage to Z-axis linear guide ► Replace the Z-axis drive.
Z-axis read unit dirty ► Clean the Z-axis read unit.
Linear guide of segment damaged ► Replace the linear guide of this segment.
Z-axis down light barrier of this segment pol-
luted
► Clean the light barrier and switching ring
through service gap.
‘CSVariation’ error for all segments
Cause Solution
Component sensor polluted ► Clean the prism at the component sensor.
Component sensor damaged ► Replace the component sensor.
‘CSVariation’ error for individual segments
Cause Solution
Linear guide of segment damaged ► Replace the linear guide.
Bad nozzle seating ► Check the nozzle interface and replace if
necessary.
