Clean the destination plate gripper grid
The grid on the destination plate gripper is charged with an electrical
current during fluid transfer. The electrical field overrides any static charge
that may reside in the destination plate to ensure that the droplets
transferred from the source plate wells are directed upward into the center
of the destination wells and not diverted to the side of the wells.
The grid should be inspected for particles and cleaned monthly.
