Introduction
Most
Bill
Acceptor
failures
are
due
to
minor
causes
.
Before
replacing
any
parts,
make
sure
that
all
assembly
and
circuit
board
connectors
are
prop
-
erly
fitted
and
the
harness
is
properly
connected
.
Faulty
bill
acceptance
by
the
Bill
Acceptor
is
often
caused
when
dust
or
iron
powder
adheres
to
the
identification
sensor,
magnetic
sensor
or
Transport
belt
.
Clean
the
acceptor
section
first,
then
observe
the
operating
state
of
the
Bill
Acceptor
in
detail
when
initializing
power
.
This
observation
is
impor
-
tant
in
locating
any
failure
causes
and
the
possible
fault
point
.
If
the
acceptor
head
has
to
be
repaired
by
disassembling
it,
always
recalibrate
the
sensors
following
a
repair
.
Perform
all
repairs
by
referring
to
the
Calibration
and
Flash

Troubleshooting
Overview
The
WBA
allows
the
operator
to
perform
fault
diagnosis
by
checking
various
fault
table
listings
against
the
symptom
and
survey
the
cause(s)
of
any
failure
occurrences
during
the
process
.
After
determining
the
cause
of
the
failure,
execute
the
Performance
Test,
perform
a
sensor
readjust
-
ment
and
then
repair
the
WBA
Unit
replacing
any
appropriate
parts
deemed
necessary
.
