The guide rails mounting holes
The
guide
rails
have a tapered end and a non-tapered
end. The tapered end is mounted
at
the
rear
of the
scanner
.
This
facilitates the
scanner
's
entry
into the
drive
bay slot. The non-tapered end mounts to the
front
of the
scanner
. This flat end
allows
the
scanner
to be
locked into position once the
scanner
is installed.
Certain holes on the
rails
are
elongated in the vertical
direction
. This
permits
precise
adjustment
of the position
of the
rails
with respect to the
scanner
. The
rails
have a
set
of horizontal holes that can be used to position the
rails
forward
or
backward
with
respect to the
scanner
.
Attaching the guide rails to the scanner
There
are
several
different
styles of
computers
. It
may
take several
tries
before the
best
combination
of
holes
are
found on the
scanner
and
rails
for
optimal
mounting
.
The face of the
scanner
has to
fit
flush with
other
peripherals
in the
drive
bays as
well
as the face of
the
computer
. In addition, the
scanner
must
slide
into the
drive
bay
without
touching any
other
devices
or
the
drive
bay. It
should
sit
so that the
cutout
in the
computer
front
panel
aligns
with the face of the
scanner
.
The process
of
properly
aligning
the
scanner
into the
computer
drive
bay can take
several
attempt
and
some
patience. It is often easiest to
eyeball
the
best
holes
while
holding
the scanner and
rails
in
front
of
the
drive
bay. Choose the position that looks best. Then
screw
the
rails
into the
side
of the
scanner
loosely
and attempt to
push the
scanner
into the bay. If
it
fits,
remove
the
scanner
, tighten the screws and continue on
with
the
installation. If not, move the
rails
with respect to the
scanner
and
try
again until
it
fits.
Sliding the scanner into the drive bay
Before the
scanner
is inserted into the
drive
bay
,
insure
that the DIP switch block is
set
correctly
. In
rare
cases,
it
may
be necessary to change the
configuration
of the
DIP switch block.
Never
force
the
scanner
into the
drive
bay
. It should
have a snug fit, yet it should not be
necessary
to
apply
excessive force when pushing in the
scanner
. If it does
not
slide
in
easily
,
reposition
the
guide
rails
or
visually
check the
drive
bay
to see
what
might
be
blocking
the
path of the scanner.
