that
with
the
car-
rier
held
to
the
extreme
left,
the
air
cylinder
plunger
is
.080" to .100" from bottoming
in
the

NOTE: Adjustments
11
and

Air
Cylinder
Orifice
- The
air
cylinder
orifice
is
adjust-
ed and
sealed
at
time
of
assembly to
provide
the
most
uni-
form
deceleration
of
the
carrier
at
the
left
margin.
Be-
fore any
attempt
to
change
th
is
adjustment,
check
for
proper torque
limiter
adjustment
and
for binds
in
the
air
cylinder
mechanism.
If
adjustment
is
necessary,
the
left
hand
orifice
should be
adjusted
first.
Approximate
set-
tings
are:
full
open
on
left
hand
orifice
and
1/2
open
on right
hand
orifice.
Too much
air
cylinder
action
or cushion
can
cause
timing
problems
due
to
the
delay
of

ing.
This
prob-
lem would be more
prevalent
on
printers
operating
