3. Head offset adjustments
Head offset is the position of a head other than Head 1, relative to Head 1. This section explains how
to adjust the head offset of standard heads and FNC (flying nozzle change) heads.
3.1 Preparation for head offset adjustments of Heads 3, 5,
and 7 (YV100Xg family) or Head 2 (YV88Xg)
1
Check the "Adjust Mode" parameter and PCB data.
Offset adjustments of Heads 3, 5, and 7 (YV100Xg family) or Head 2 (YV88Xg) use a
glass QFP, so the machine must be set to "Adjust Mode2" and the "MCH_SETUP"
PCB data loaded into the machine.
You can check the currently selected PCB data and "Adjust Mode" on the status bar.
