Slice lip profile deviating from the flat setpoint due to actuator drift or fouling
Turbulence insert partially blocked by fiber or filler deposits reducing local jet velocity
Manifold flow distribution uneven across the machine width
Feed pump pressure fluctuation creating a whole-width CD variation
Stock infiltration and hardening around the actuator stem and seal
Corrosion binding the actuator screw from prolonged exposure to wet stock
Failed actuator motor or gearbox preventing movement
Wiring fault preventing the actuator from receiving the control signal

How to reduce CD basis weight variation on a Voith MasterJet Pro Headbox
CD basis weight variation is most often caused by turbulence insert fouling or slice lip profile error. Scan the CD profile, adjust the slice lip, and inspect the turbulence insert.
How to diagnose foam formation problems on a Voith MasterJet Pro Headbox
Foam in the headbox causes formation defects and CD density variation. Check defoamer injection rate and stock system air entrainment sources before adjusting headbox consistency.
How to fix a sticking slice actuator on a Voith MasterJet Pro Headbox
A sticking slice actuator creates a fixed CD basis weight hump that does not respond to control commands. Identify the stuck actuator from position feedback, lubricate or replace it at the next outage.
