CAUSE: Too much powder accumulation in system components is often associated with leaks in the recovery system (absolute-filter, cyclone, hose connections, etc.)
CORRECTION: Check for leaks
CAUSE: In cyclone systems, peristaltic feed pumps or powder feed pumps can wear or clog
CORRECTION: Check powder recirculation system for function and leak-tightness
CAUSE: Clogged sieve mesh can substantially minimize separation
CORRECTION: Clean powder sieve regularly
