PreDisp Check Description
Use
• Checks the dispensing amount after correction. The head moves 20 mm in the Y direction by
utilizing the correction amount obtained by the first predispensing and performs dispensing and
recognition (for mark check).
• Performs predispensing immediately before dot dispensing for the corresponding head.
Not Use All heads perform predispensing before starting dot dispensing.
c
CAUTION
When the correction amount check is used, the predispensing and dot recognition count increases, causing the
production cycle to become longer.
