The error ‘Component length outside tolerance’ occasionally occurs with 0402 components. This
is generally caused by dirty nozzles.
It can also occasionally occur with 0402 components with a dark body and very narrow leads,
even though the nozzles are clean. In this case, you should change parameter P2a under ‘Size’
from 10 to 11.
