the
final
wizard
screen,
choose
to
either
repeat
the
head

procedure
or
close
the

the

run
the

‐
alignment
wizard
again.
The

wizard
will
allow
you
to
“fine
tune”
the
alignment.

the
vertical
lines
for
the
heads
were
not
aligned

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—
Head
Heater
temperature
timeout
Head

Head

•
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.
