Contaminants have damaged the air supply system in the device or have otherwise restricted the airflow.
To correct the error:
Check your air supply system for the following:
Ensure that the air hose connected to the device has sufficient air pressure.
Ensure that the system air pressure gauge on the
device reads 100 to 120 psi.
On semi-automatic and ContinuousLoad devices, the air pressure gauge
is located behind the air supply filter panel.
For MCU devices, the air pressure gauge is located behind the rear
panel of the slip sheet removal unit.
Adjust the external air supply if necessary.
