Quadalign is very similar to the Samsung. I would think that 4% dump on 1206 or even IC is way over the top. If you are certain that your component data is correct; I suspect that your z-axis centring height may be out of whack and that you are eith

Check to see if its the same component everytime if so check part height . Also check Z0.This setup is in the manual. You say this only happens after maintenance is carried out so when you free the nozzle it doesnt happen again until maintenance is
