Changing the Printing Material
Before producing models using a different type of printing material than is
currently installed, run the Material Replacement wizard to flush the print
block and feed tubes.
After using the wizard to change the Support material and certain Model
materials, Head Optimization is required before printing models.
You should carefully plan printing models with different Model materials to
avoid unnecessary waste of the materials currently loaded. The amount of
material flushed depends on the flushing cycle chosen and if you are replacing
one or more Model cartridges.
The Material Replacement wizard suggests the best slot locations for placing
different material cartridges, based on the materials currently in the system.
This ensures minimum flushing of materials currently loaded.
To replace the printing material with the wizard:
1. Start the Material Replacement wizard from the Options menu.
2. In the opening screen, click Next.
3. If the printer cover is not closed, a screen appears, prompting you to close
