alignment.

The condition of the print heads directly affects the quality of printed
models. To maintain optimum printing, test the print heads, and calibrate
them to the best working configuration possible by running the Head
Optimization wizard. This procedure takes about one hour to complete.
During the optimization process, samples are printed on the build tray.
After carefully inspecting and weighing each of them, you enter data in the
wizard. The wizard uses this data to optimize the 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. This procedure takes about 2.5 hours
more to complete.
Run the Head Optimization wizard every 300 hours of printing or whenever
the condition of print heads is negatively affecting the quality of printed
models, or if you suspect that there is a problem with one or more of the
print heads.
