Offset
Teaching
The
following
explains
about
causes
and
remedies
(
troubleshooting
)
in
order
of
frequency
.
Stained
Nozzle
Distinction
:
Lighting
check
results
in
NG
on
a
specific
nozzle
.
An
NG
factor
may
be
found
visually
in
the
nozzle
image
on
the
recognition
monitor
.
Remedy
:
Wipe
the
nozzle
end
and
the
tapered
area
with
a
soft
cloth
.
Stained
Glass
Surface
of
Ring
Lighting
Distinction
:
Lighting
check
results
in
NG
on
almost
all
heads
and
nozzles
.
Remedy
:
Remove
any
foreign
residues
from
the
glass
surface
and
wipe
the
surface
with
a
soft
dry
cloth
.
Stained
Diffusion
Plate
Distinction
:
Lighting
check
results
in
NG
on
specific
heads
and
nozzles
.
Remedy
:
Wipe
the
diffusion
plate
(
red
acrylic
plate
on
the
lower
surface
of
placement
head
)
with
a
soft
cloth
.
Deterioration
of
Lighting
Distinction
:
When
the
level
of
deterioration
is
small
,
light
checking
results
in
NG
on
a
specific
nozzle
.
When
there
is
considerable
deterioration
,
NG
is
caused
on
almost
all
heads
and
nozzles
.
Remedy
:
Consult
our
service
personnel
for
re
-
adjustment
of
the
light
source
unit
.
Replace
the
lamp
of
the
light
source
unit
.
Adjust
the
image
input
parameters
.
Time
for
Lamp
Replacement
The
lighting
deterioration
rate
of
the
halogen
lamp
which
appears
after
longterm
use
is
10
%
when
power
is
supplied
for
5
,
000
-
6
,
000
hours
(
=
Approx
.
7
8
months
)
.
While
the
lighting
deterioration
rate
is
10
%
-
20
%
(
Approx
.
1
-
year
use
under
normal
condition
)
,
the
lamp
must
be
replaced
with
a
new
one
.
Reproducibility
of
Component
Recognition
Lighting
Teaching
Result
The
halogen
lamp
used
for
component
recognition
lighting
normally
shows
the
deterioration
of
lighting
after
longterm
use
.
In
addition
,
some
changes
in
the
light
intensity
are
caused
due
to
ambient
temperature
and
the
time
of
power
supply
.
Therefore
,
a
result
of
lighting
check
sometimes
shows
OK
or
NG
depending
upon
the
time
frame
and
/
or
the
room
temperature
when
component
recognition
lighting
teaching
operation
was
performed
and
the
lighting
condition
is
very
similar
to
the
detection
criteria
.
When
maintenance
work
is
done
but
component
recognition
lighting
teaching
operation
still
results
in
NG
there
might
be
a
sizeable
difference
between
the
pre
-
adjustment
at
shipment
and
the
actual
environmental
condition
.
In
this
case
,
consult
our
service
personnel
for
detailed
information
.
