plate configuration, or improper needle height or well plate height is

set manually. Needle obstruction, maybe due to incorrect sample rack

or well plate configuration or any unexpected object. Check if the

correct sample rack or well plate is configured. Consider number of

positions of the configured sample rack or well plate as well as the

respective well plate height. Or check any unexpected object. After

resolving physical blockage, then run self-test to recover the issue.
