Multiple attempts had been made to obtain additional information and receive the device.Supplier: crosstex/sps.Manufacturing site evaluation: no samples were returned for evaluation in connection with the complaint.However, the malfunction has been confirmed through the (scar) - supplier corrective action report where similar defects with other complaints have been known to occur.Root cause - primary - ink viscosity was too high.Highly viscous ink becomes affixed to machinery and results in splatter.Secondary - no means of measuring viscosity nor a specification to measure against.Immediate actions - included an increase in quality control inspections, awareness training to operators was performed.Additionally, the press doctor blade was changed daily.Corrective action - a viscometer was acquired to measure ink viscosity.Subsequent data collection to determine optimal viscosity range.
