Testing and
Calibrating the
UV Lamps
The
effective
radiation
of
the
UV
lamps
used
for
curing
models
can
change
over
time.
To
ensure
optimum
curing
of
models
during
printing,
a
pop
‐
up
message
reminds
you
to
test
the
lamps
and
calibrate
their
effective
UV
radiation
after
every
200
hours
of
printing.
You
do
this
by
running
the
UV
Calibration
Wizard
and
using
the
built
‐
in
UV
radiation
sensor.
The
wizard
compares
the
radiation
you
measure
to
the
recommended
radiation
level
for
each
of
the
lamps,
at
each
printing
mode—High
Speed,
High
Quality
and
Digital
Material.
The
radiation
level
is
considered
acceptable
if
it
is
within
seven
percent
of
the
recommended
level.
When
calibrating
the
lamps,
the
wizard
attempts
to
adjust
the
radiation
level,
if
necessary,
and
then
prompts
you
to
take
a
new
reading.
If
the
level
is
acceptable,
the
wizard
continues
to
the
next
phase.
If
further
adjustment
is
necessary,
the
current
phase
is
repeated.
If
the
level
is
too
low
to
be
adjusted,
the
wizard
continues
to
the
next
phase;
the
final
wizard
screen
indicates
that
the
lamp’s
radiation
for
the
printing
mode
is
unacceptable.
To test and calibrate UV lamp radiation:
1. Start
the
UV
Calibration
wizard
from
the
Options
menu
(see
figure 7
‐
26
on
page 23).
2. Make
sure
that
the
build
tray
is
empty,
the
UV
sensor
is
exposed
and
clean,
and
that
the
printer
cover
is
closed.
Confirm
this
in
the
wizard
screen
and
click
Next
.
Figure 7-76: Confirmation screen
The
UV
lamps
power
up
and
stabilize;
this
takes
several
minutes.
Then,
the
block
passes
over
the
sensor.
The
wizard
compares
the
measured
radiation
to
the
recommended
level
for
the
lamp
and
printing
mode
tested,
and
displays
the
result.
The
wizard
continues
as
follows:
•
If
the
level
measured
in
the
previous
test
is
acceptable,
the
wizard
begins
testing
the
left
UV
lamp.
•
If
the
level
measured
in
the
previous
test
is
not
acceptable,
the
wizard
calibrates
the
right
UV
lamp
by
adjusting
the
current
supplied
to
it,
then
tests
it
again.
•
If
the
level
measured
in
the
previous
test
is
too
low
to
be
adjusted,
the
wizard
records
the
lamp’s
radiation
as
unacceptable,
and
begins
testing
the
left
UV
lamp.
