Dynamic Nozzle Test

indicated by the Pattern Test.
The Dynamic Nozzle Test prints eight (8) samples on the build tray, which you
can then visually inspect. Printing the samples takes about 20 minutes.

❒ In the left sample shown above, there are no gaps.
❒ In the right sample shown above, there are only two gaps, which is

Many gaps in the sample indicates that many nozzles in the print head are
not functioning. This might indicate the need to replace the defective head.
In this case, consult with your Stratasys service provider.
