6.24.3 Interpretation of the results obtained
‘Max value’ or ‘LED gain’ error for all segments
Cause Solution
Z-axis down light barrier polluted ► Clean the light barrier using a cleaning
stick and isopropanol.
Surface of Z-axis down light barrier damaged ► Replace the light barrier.
‘Max value’ or ‘LED gain’ error for individual segments
Cause Solution
Switch ring polluted ► Clean the switch ring using a cleaning stick
and isopropanol.
Surface of switch ring damaged ► Replace the respective DP.
‘Radial runout 5° / 360°’ or ‘Variation 5° / 360°’ error for individual segments
Cause Solution
Segment bent, e.g. due to head crash ► Replace the DP.

6.25 Z positioning time
Software Manual SIPLACE Head Verification 03/2018 87
6.25 Z positioning time
6.25.1 Measurement principle
The Z positioning time measurement checks the consistency of the Z-axis positioning and indic-
ates the condition of the Z-axis drive and linear guide.
●
The Z-axis is positioned up and down to the exact same position 20 times. For each position-
ing action, the time is determined it took the Z-axis to reach the position. If the Z-axis moves
easily to the position, the Z-axis drive and linear guide are in good condition.
●
If the Z-axis is not moving smoothly, a mechanical problem exists.

1 Minimum, maximum and average time determined to reach the target position.
2 Graph showing the Z-axis positioning time.
6.25.3 Interpretation of the results obtained
‘Z positioning time’ error
Cause Solution
Blockage at the Z-axis linear bearing ► Check / maintain the linear bearing.
Z-axis drive and/or linear bearing defective ► Check / maintain the linear bearing.
► Replace the P&P module.
► Send the P&P module to ASM for cus-
tomer specific repair.
