Backlash Check
Measuring Locations:
Outer circumference:
Location
where
dimension
A
in
the
figure
at
right
(space
between
FOP
and
press plate B) is 3-5 mm.
retainer A
Middle:
Location where gear C engagement point
is at the center of the rack.
Inner circumference:
Where
dimension
B at right
(space between FOP and re-
tainer A) is 3-5 mm.
Measuring Procedure:
1.
Apply
3 V to sled motor lead and move the
FOP
to
the
measuring
location.

2.
At each measuring location, check that there is
no movement
in the directions of the arrows
marked
@
and @
when S50 g(2 oz) is app-
lied to a fan-shaped tension gauge.
3.
If there
is movement,
sled
motor
mounting
should be redone. (Sled Motor Assembly.)
Sled Motor Response Check
If the following check is not satisfied, replace the
sled motor (M901).
©@ Minimum Activation Voltage Check.
1.
Apply
1.5 V and
check that the FOP moves
smoothly
from the inner to the outer circum-
ference.
Next apply 2 V and check that the FOP moves
smoothly from the outer to the inner circum-
ference,

Sled Sending Current Check
1.
Apply 3 V and move the FOP from the inner-
most
to the outermost
circumference.
Check
that current value is less than 120 mA at this
time.

2.
Next move the FOP from the outermost to the
innermost
circumference.
Check
that current
value is less than 150 mA at this time.
@
Sled Sending Time Check
Apply 3 V, and check that the time for the FOP to
move
from
the innermost
to the outermost
cir-
cumference
and from the outermost to the inner-
most circumference is less than 5 seconds each.
