Full Material Changeover (MCO)

Download as PDF

For successful build jobs, when a user wants to switch from one part material to another without material mixing, a full Material Changeover (MCO) must be performed. A full MCO is required when switching from a rigid material to a elastomeric material or vise versa. 

NOTE: Please ensure you have replaced the waste bag with a new empty one PRIOR to starting the Material Changeover Procedure. Also, ensure you have the required materials for the material change – two MCO Cleaner 2500 cartridges, two new part material cartridges and two support material cartridges for head maintenance cycles.

NOTE: Full-MCO requires two support cartridges present to complete successfully.

NOTE: If MCO is not performed correctly, the color profile of the new installed material may have residual original material color.
  1. Ensure printer is in Ready state. Select Tools > Material Change Wizard from the UI.
