Manual,

Service Maintenance Information,
4691.
The
4691
is
shipped with spiral hoses
hooked
up
to the
air
inlet
of the
ink
jet
heads.
The
spiral hoses are only
part
of the shipping paraphernalia
and
should
be
removed
when
the
4691
is
installed.
At
installation,
the spiral
hose
and
its
attendant
1"
piece of
rubber tubing should
be
removed
from
each
head.
The
air
lines are then
hooked
up
to the remaining short piece
of rubber tubing
coming
from
the
air
inlet
on
each
head.
Hooking
the
air
lines
up
to the
end
of the
spiral
hoses
and
then operating the units
in
such
manner
may
cause a spurious
splatter
on
the copies.
