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: FullMCO 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. 
NOTE: This step can take 3045 minutes to complete while it removes the old part material from the printer. 

NOTE: If the cartridges are cold the process will take an additional 30 minutes to allow material to warm before continuing. 
NOTE: If the cartridges are cold the process will take an additional 30 minutes to allow material to warm before continuing. 
The Pass Though Material Changeover gives the option for different rigid materials to be swapped out without performing a Material Changeover (MCO).
NOTE: Performing a Pass Through MCO will have some material mixing. This option is only applied to rigid materials. 
Select Material Changeover if you would like to have no mixing between materials. This option will perform a full MCO.
or
Select Begin using VisiJet M2 xxx. Materials will have some mixing.
or
Select Continue using VisiJet M2 xxx. Reinstall the currently used material.
Below is the Material Change Over (MCO) Matrix. This matrix shows the required action when switching materials.
F= Full MCO required
N= No MCO, print through okay
F, N = Give the user the option to do a "Full MCO" or choose to just insert bottles and do "No MCO"

An extended material changeover is required when moving from M2EBK70 to any other VisiJet material. The extended changeover wizard will be automatically initiated by the printer and requires no special knowledge from the user. The extended changeover requires a 12 hour deep clean; this is best done overnight. The extended material changeover takes approximately 500g per bottle of cleaner material, so the bottles must be at least 50% full.
NOTE: This step can take 3045 minutes to complete.  
NOTE: If the cartridges are cold the process will take an additional 30 minutes to allow material to warm before continuing.
