procedure or close the wizard.

If the most closely aligned vertical lines for a print head were at
either extreme—the first or seventh lines—choose Yes to run the
head ‐ alignment wizard again.
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.
•
If the vertical lines for the print heads were not aligned at either
extreme, choose No to close the wizard.
Replacing
Printing Heads
You need to replace a printing head if one or more of the following
symptoms occurs:
•
The pattern test reveals that more than 15 nozzles are not functioning in
one area of the head.
•
Visual inspection reveals that the surface of the head is damaged—
peeling or bubbles in the nozzle area.
•
The Eden interface displays a warning or malfunction message relating
to a printing head—
ˆ Head Heater temperature timeout
ˆ Head Heater thermistor open
ˆ
Head Heater thermistor short
•
Tests reveal that the material printed by a printing head is underweight
(that is, not enough material is being outputted).
Note: Weight tests are performed only by an authorized service engineer.
Replacing print heads is expensive. Replace them only after consulting with
customer support to determine that head replacement is necessary.
