Setting up the Scanner
Setting up the Scanner
Environmental Requirements
Set up the scanner in a location that fulfils the following requirements:
• Keep the scanner away from sources of heat, such as direct sunlight or
a radiator. Warm temperatures will degrade the quality of your scans -
for best results, work in a cool environment.
• The scanner must be operated away from sources of strong
electromagnetic interference. Although the scanner complies with all
regulations governing electromagnetic immunity and Hasselblad has
taken every reasonable step to make the unit immune to
electromagnetic interference, it is still a precision electronic device so
strong radio waves can interfere with your scans.
• The surface on which the scanner is placed must be stable and free
from vibrations. If the scanner is shaken or moved while scanning,
your results may be affected.
• If the scanner has been in a colder environment (e.g. outside or in
storage) just before you set it up in a warmer room, then wait about
two hours before using it - otherwise, condensation may form, which
will prevent the scanner from operating correctly.
• Avoid using the scanner in areas where there is a high level of dust.
Electrical Requirements
The Flextight 848 power supply requires a mains voltage of between 100
and 240 V AC at a frequency of 50 to 60 Hz. This is within the normal
wall-socket power standards of most countries. Do not attempt to use
Flextight 848 with any power source outside the specified range.
The scanner and all devices attached to the scanner (computer, monitor,
FireWire devices, etc.) must be grounded (i.e. use a three-point electrical
connection).
Note that the power supply may emit a low hissing sound when
plugged in but not connected to the scanner. This is normal and will not
damage the power supply or scanner.

Setting up the Scanner
Installation Procedure, FireWire Interface
1. Place the scanner on a table near your computer with the front
facing away from you. Make sure that the location you choose meets
all environmental - and electrical requirements as described on page
11.
2. When using a FireWire interface connection, it is not necessary to
switch of your computer and other connected units. Connect a
FireWire cable from one of the FireWire connectors on your scanner
(see Back Panel & Connectors on page 10) to either the computer's
FireWire connector or to a free FireWire connector on any other
FireWire device already connected to your computer.
3. Connect the round connector from your power supply to the round
power supply socket on the back of the scanner.
4. IMPORTANT: Make sure that the wall socket you are planning to
use meets the electrical requirements outlined earlier.
Plug the Flextight 848 power supply into a wall socket. Note that the
power supply may emit a low buzzing sound when plugged in. This
is normal and will not damage the power supply or scanner.
5. Turn the scanner around so that the front is facing you.
6. Your system is assembled. Turn on your computer and install the
FlexColor image scanning software.

Operating Instructions
(See Figure 4 opposite).
1. It is assumed that the scanner and FlexColor software have been
properly installed.
2. If not already done, turn the feed table (A) to normal position.
3. Press the red power button (F) on the front of the scanner to switch it
on. The green light (G) starts flashing. This means that no firmware
has been downloaded yet. It will be downloaded automatically later
when you first run the FlexColor program.
4. Turn on your computer and start the FlexColor program. The green
light (G) will stop flashing indicating that firmware has been
downloaded to the scanner.
5. Select the original holder (K) that matches your original:
• For transparencies, choose one of the holders that has a square
hole in it. The original must completely fill the hole with no edges
showing. Also, no edges of the original must extend past the outer
edges of the holder.
The feed table (A) must be in normal position.
• For reflectives, select the large A4/letter-size holder with the clear
plastic layer.
The feed table (A) must be in normal position.
• For 35 mm slide frames use the optional 35 mm slide mount
holder.
The feed table (A) must be adjusted to horizontal position. This is
obtained by lifting the table slightly upwards while pushing it
gently into the scanner.
Please note that when scanning 35 mm slide frames in the 35 mm
slide mount holder it is recommended to use autofocus. See the
FlexColor Software Reference for details.

NOTE! Each original holder has it's own unique identification code
(a combination of small rectangular holes at the holder's leading
edge). These codes, combined with the scanner's ability to detect the
feed table position, ensure that the scanner will not operate unless
the feed table position matches the selected original holder.
6. Place the original holder (K) with the slotted tab facing into the
scanner. For transparencies, the flexible magnetic layer must face
upwards. For reflectives, the clear plastic sheet must face upwards.
Make sure that the original holder fits between the appropriate
guides (C) or (D) on both sides of the light table.
7. Slide the holder gently into the slot (E) at the top of the feed table. It
will slip about ½ cm (1/4 inch) into it. Do not press too hard. It slips
in very easily and is held in place by a magnetic clasp. To remove
the holder, simply pull it gently backwards.
8. Lift the top layer of the original holder and place your original (L) as
follows:
• For transparencies, place your original with the emulsion side
down. The original must completely fill the hole with no edges
showing and with a minimum overlap of 2mm along each edge.
Also, no edges of the original must extend past the outer edges of
the holder. Use the grid on the light table (B) to help line up the
image.
• For reflectives, make sure that no part of the original extends past
the edge of the holder. Use the dotted lines printed on the holder
to line up the image. Handle the clear plastic layer only by the
edges to avoid fingerprints. Curl the plastic layer back and slip
the front edge into Flextight's foil holder.

9. Lay the top layer of the holder down flat over the original.
• For transparency holders, the top layer is magnetic, which will
hold the original fast.
• For the reflective holder, note the four metal pegs (the top two are
shown as A and C in Figure 5 below); make sure that the clear
plastic sheet is pressed all the way down over all four pegs. Note
also the two curved tabs at the top of the holder (B in the figure
below); the clear sheet must slip under each of these tabs, as
shown.

Calibrating the Scanner
Calibrating the Scanner
The scanner requires two types of calibration:
• Focus calibration adjusts the positioning of the scanners optics for
each zoom level. If your scans are coming out unfocused or at slightly
the wrong size, then you may need to make a new focus calibration to
adjust the zoom mechanism. The focus calibration is stored in the
scanners flash PROM, so it is preserved when you move the scanner to
a new computer. See "Focus Calibration" on page 21 for more
information.
• White calibration is only required for reflective scans (it is done
automatically for transparencies). During calibration, the scanner
scans a white target to establish the white point along the full length
of the scanners CCD. The results of the white calibration scan are
saved on your computers hard disk, so you must make a new white
calibration if you move the scanner to a new computer. See "White
Calibration for Reflectives" on page 22 for more information.
Both of the calibration procedures are simple and are initiated from the
FlexColor program.

Calibrating the Scanner
Focus Calibration
The Flextight 848 scanner uses an adjustable zoom and focus mechanism
to optimize its scanning resolution for each of the original formats it can
handle. If you suspect your scans are not as sharp as they should be, then
you may need to calibrate your scanner. Note that you must not calibrate
the scanner every day. It is intended that the scanner is calibrated not
more than once every three months. In most cases, this procedure will
never be necessary.
Use procedure below to make Focus Calibration:
1. Locate the "Focus sheet" that came with your scanner. It is a 8 x 9 cm
(3" x 3.5") square of transparent film with a black image on it.
Focus sheet
PN:40900026, rev. 1.10
2. Load the sheet into the 6 x 6 original holder with the lines pointing
towards the scanner (vertically). Place the sheet as straight as
possible. Use the scanners light table grid and the corners marked on
the sheet to help align it.
3. Select Focus Calibration from the Maintenance menu.
4. Click on the Calibrate button, and the focus calibration starts.
5. When the focus calibration is finalized, the focus calibration window
closes again.
Your scanner is now calibrated for all resolutions and for both
transparent and reflective originals.

Calibrating the Scanner
White Calibration for Reflectives
The Flextight scanner uses a white reference to make sure that all
elements in the scanner's CCD react consistently to light brightnesses.
The scanner has been calibrated from the factory, and the calibration
data is stored in the scanner’s flash PROM.
As the scanner ages, the properties of the light tubes may change
slightly. Therefore, you must redo the white calibration every six months
or so and immediately after changing the light tubes.
Use procedure below to make White Calibration:
1. Find the white calibration sheet that came with your scanner. It is a
square white piece of paper (219 x 219 mm (8.6" x 8.6")).
If you have lost the white calibration sheet, then you can use a flat
(non-textured), perfectly white piece of paper of the same
dimensions.
2. Your scanner came with several clear plastic layers for the reflective
original holder. If you have used the reflective holder before, make
sure that there are no finger prints or other marks on the plastic
layer. Replace the layer with a new one if necessary.
3. Align the top edge of the sheet with the dotted line near the top of
the original holder (see Figure 6 opposite). Align each side of the
target with the edges of the original holder.
4. Select White Calibration from the Maintenance window. The
External White Calibration window appears.

The Light Tubes
The Light Tubes
General
The Flextight 848 contains two light tubes: one for illuminating reflective
originals from above, the other for shining light through transparencies
from below.
Replacing the Light Tubes
If your scans are suddenly coming out black (or all white if you are
scanning negatives), then one of your light tubes may be defective.
Make a preview using both types of scans (transparent and reflective) to
find out which tube is affected.
• If transparencies are not working, then the bottom tube may be
burned out.
• If reflectives are not working, then the top tube may be burned out.
Follow procedure below to replace a tube:
(See Figure 7 opposite).
1. Get the appropriate replacement lamp (ask your Flextight dealer).
2. Turn off and unplug the scanner from the primary power supply.
3. IMPORTANT: Let the light tubes cool down for app. 10 minutes
before proceeding.
3. Remove the front panel (A) by pulling it outwards at the bottom and
lift it off.
4. Remove the two black allen screws (B) (one in each side) using a 3
mm allen key. Do not remove any other screws.
5. Remove the two side panels (C) and (D) by lifting them slightly
upwards and then outwards.
NOTE! It may require a firm push upwards to release the panels.
6. Turn the feed table (E) to upright position.
7. Locate the tube to be replaced and dismount the plug (F).
