The transparency test will show if the heads are now properly aligned,
and—if not—the wizard will allow you to “fine tune” the alignment.

Optimizing
(Calibrating)
Print Heads
The condition of the print heads directly affects the quality of printed models.
To maintain optimum printing, you should routinely test the print heads, and
calibrate them to the best working configuration possible by running the
Head Optimization wizard every 300 hours of printing.
During this procedure, you place a scale on the build tray and connect it to
the printer. Printing material (resin) is jetted from each head and its weight is
automatically recorded and the wizard determines how to optimize the print
heads.
If, during the optimization process, the wizard determines that a print head is
faulty—or that it is negatively affecting layer uniformity with the current head
configuration—the wizard instructs you to replace it. If this happens, you can
continue the wizard to replace the print head, or abort the wizard, to replace
the head at another time.
