sensor does
not
move.
The mark
sensor
is moved
right
and
left
by the
mark
sensor
clamp
screw
which
is
connected
to
the
spiral
shaft
for
mark
sensor.
The spiral
shaft
is
moved
by the
gear
253 which
is
connected
to
the
DC
motor.
The DC motor is controlled by the
signal
of
the
computor which
is
passed
through the driving
circuit
of the
DC
motor.
3-1.
Turn
off
the
power
switch
and
turn
the
gear
Z53 of the
spiral
shaft,
it
must
move
smoothly.
lf
turning
of
the
spiral
shaft
is
too
heavy.
1).
The
metal part of the
spiral
shaft
lacks
oil.
Put
the
specified
grese
on
the metal part
of
the
spiral shaft.
2).
The
oil
sticks
to
the
spiral
shaft
and
mark
sensor does
not
slide smooth-
ly.
Clean
up
the
oil
with
a
cloth
and adjust
the
mark
sensortoslidesmooth-
ly.
3).
The
DC
motor
is
not
mounted
correctly, the
DC
motor
gear
and
the
gear
Z53
are
not
engaged
correctly.
Make sure
that
the shaft
of the
DC
motor
is
installed
to
the
hole
of
the
card guide
A
correctly.
Make
sure
that
the shaft of the
DC
motor
does
not
slant.
lf
the
DC motor
is
not
mounted
correctly, the
mark
sensor makes
an
abnormal sound
when
it
is
moving.
Adjust the setting of the
DC
motor.
4).
The spiral
shfat
is
bent.
Replace
the
spiral
shaft
with
a
new
one.
3-2.
When
turning on the
power switch.
the
DC
motor
works
but the
mark
sensor does
not
move.
1).
The mark
sensor
clamp screw
is
loosened and
it
does
not connect
to
the
spiral shaft.
lf
the mark
sensor
clamp screw
is
worn out,
replace
it with
a
new one.
Set
the mark
sensor
clamp
screw
to
the spiral shaft
correctly
and
fasten
it.
2).
The
DC
motor
gear
or the
gear
Z53
are
worn
out.
Replace
the
DC
motor
or the
gear
253
with
a
new one.
3-3.
The
DC
motor
does
not
turn.
Check
the
fuse
(F201) which
is
installed on
the
power
supply
board.
lf
the
fuse
(F201
)
is
broken,
replace
it
with
a
new one
after
replacing
it,
check
the
driving
circuit
of the
DC
motor on the
power supply board
or the
DC
motor itself
and
find
the short-circuit
parts
on
them then,
turn
on
the
power
switch.
Check
the driving
circuit
of
the
DC
motor.
Remove
the
fuse
(F201)
and check
the
resistance
of
the
driving
circuitof
the
DC
mortor.
Set
the
tester
to
the
Sl
x
1
range
and connect
the
black
terminal
of it to
the
right
side
of
the
fuse
clip
and
the
red
terminal
to
the
machine
body.
lf
the
indicator
shows
-Sl,
there
is
no
short-circuit
on
the driving
circuit of
the
DC
motor.
Check
the
DC
motor.
Pull out the
connector
58
of
the
DC
motor
from
the
power
supply
board
and
check
the
resistance
of
the
DC
motor
by setting the
tester
to
the
Q
x
1 range.
Connect
the, terminals
of
the
tester
to
the
pins
of
the connector
S8.
lf
the
indicator
of
the
tester shows
20S1,
there
is no
short-circuit
on
it
and
also no
disconnection.
Check
the
control
signal
for
the
DC
motor.
Pull out the connector 56
from
the main
P.C.B. and
turn
on
the
power
switch.
Check
the
voltage
for
No.
6, 7
and
8
pins
of
the
connector
P6
on the
main
P.C.B.
by
setting
the
tester
to
the DCV
10
range.
Connect
the
black terminal
of
the
tester
to the
metal
parts
of
the
machine
body
and
the
red
terminal
