9. TROUBLE SHOOTING
1.
G carriage does not
move.
(I)
The
G carriage
does not
move from
the
beginning.
1 The motor
does
not
run.
(1) Check to be sure that the power
cord
is
connected
with
the outlet.
(2) Check to be
sure
that the pin plug is
connected.
(3) Check to be sure that the detecting bar
comes
down.
(4) Check to be sure
that
the electric
system
is free from
troubles.
Detach
the
pin plug
from the
G
carriage
and connect the
part A with
the
plus
side of the tester bar and the part
B
with the minus
side
with
the tester set
to the DCV range.
Check to be
sure
that the
output
voltage is within
the
range
from
ltV to 13V.
a
When the pin plug
is not
loaded
with the
output voltage
•
Check
the adaptor.
A
•
Plug
out
from the AC
receptacle.
B~
•
Check
to
be
sure that the fuse
F
I 0 I
is
not
burnt.
When
the
fuse
is broken
Set
the tester
to
the
ohm
range
x
I
and
connect
the plus
side of
the
tester
bar
with
the
white part and
the minus side
with
the black
part
for check-
ing the value of
resistance.
•
When zero ohm
Detach
the
DC
cord
from the
board, set the tester to
the ohm range
x 1,
and
connect
the
plus side
of the
-31
-
tester bar
with
the
while
wire of the DC
cord
and the
minus side with the black wire.
When
the tester indicates zero
ohm,
replace the DC
cord
and the
curl
cord.
When
the tester indicates ohm, replace the power board.
•
When
not zero ohm
Replace the
fuse and
connect
with the AC
receptacle
with the DC plug
disconnected with the
carriage.
When
the fuse is broken again, replace the power board.
When
the fuse is not broken, check the output voltage
of
the pin plug
again.
If
no
abnormality
is
found
,
the
adapter functions normally.
2 When
the
fuse
is not broken
Connect with
the
AC
receptacle.
Set
the tester to
the DCV
range and connect the plus side
of
the tester
bar
with
the
white part
and the minus side
with the black part
to check that the output voltage
is
within the range
from IIV to J3V.
•
When
DC
voltage
Replace
the
DC
cord and the curl
cord.
•
When
not
DC
voltage
Set the
tester
to the
ACV
range and check the voltage of
AC 1
and
AC2
;
AC
1
14V
-
ISV
AC2
9V-IOV
When
the voltage
of
AC 1
&
AC
2 is normal, replace the
power board.
When
the voltage of AC I
&
AC
2
is not normal, replace
the adaptor.
