removed from inside the scanner:
Catches on each side of the scanner top cover are depressed to open the lid. Fit the support stay on the left-hand side (circled)
•Remove the piece of foam and retain with the packaging for the scanner (always replace this item when transporting SmartLF)
While supporting the scanner lid with your right hand release and store the stay and then gently lower the lid to close it.
Fit the three paper support trays by compressing (springing) them into the slots on the back of the scanner (the precise design may vary)
Connect the scanner to the electricity supply using the localised cable provided
IMPORTANT – DO NOT CONNECT THE SCANNER TO THE COMPUTER UNTIL INSTRUCTED
8. GETTING ACCESS TO THE GLASS AND ROLLERS OF SMARTLF
The SmartLF Gx/GxT has a hinged clamshell style lid. Opening the lid provides access to the scanner optics. With
the lid in the open position with the safety catch applied the scanner glass and rollers can be inspected and cleaned if
required. On the GxT version the lid also raises (parallel motion) under motor control. Always motor return the lid to
the fully closed position before attempting to open the lid for cleaning. Do not attempt to clean the glass through the
document aperture as this could damage the lid raising mechanism.
OPENING THE LID
WARNING
8.1 Always use two hands to open the lid by
releasing both catches simultaneously and then
lifting the lid to about 70 º
8.2 Move one hand to the centre of the lid to steady
it while using the other hand to secure the safety
catch.
It is essential to use the safety catch when
cleaning or inspecting the scanner optics for
dirt or dust contamination
8.3 Do not allow the lid of the SmartLF Gx or GxT
scanner to rest in the fully backward position.
Instead always ensure the lid is held forward on
the safety catch to avoid the risk of injury or
damage to the scanner from the lid being
allowed to fall into the shut position.

9. DOCUMENT THICKNESS CAPABILITY OF SMARTLF GX/GXT
SmartLF Gx and GxT scanners in closed mode can accept media up to
0.02” (0.5mm) thick. GxT scanners can be adjusted semi-automatically to
accept documents between 0.02” (0.5mm) and 0.8” (20mm) in thickness.
LOADING A THICK DOCUMENT
DO NOT PRESS THE OPEN OR CLOSE BUTTONS DURING
SCANNING, AS THIS WILL STOP THE SCANNER IMMEDIATELY
AUTO PAPER LOAD IS DISABLED IN THICK DOCUMENT MODE
RETURNING SMARTLF GXT TO STANDARD THICKNESS MODE
SmartLF Gx is now returned to standard thickness mode. Note that pressing OPEN or CLOSE during scanning will
stop the scanner and is equivalent to pressing the STOP button.
10. CLOSING THE LID OF SMARTLF GX/GXT
To close the lid of the SmartLF Gx/GxT after inspecting the glass or cleaning the optical area, first check that there are
no obstructions. Support the lid at the centre using the right hand and then with the left-hand release the safety catch.
DO NOT ALLOW AN UN-PROPPED LID TO FALL FROM THE RAISED POSITION AS SERIOUS SCANNER
DAMAGE MAY OCCUR. Carefully and evenly lower the scanner lid until both catches engage with their locks. It is not
necessary to use extra pressure on the lid once the catches have engaged. (TIP – The lid may need to be lifted
slightly to disengage the safety catch). THICK MEDIA - Always use the OPEN/ CLOSE buttons to lower the lid from
the thick media position. Never exert pressure on the lid to close it from the raised position.
THICK MEDIA OPEN/ CLOSE LOWERING CLOSED
WARNING: KEEP FINGERS CLEAR OF THE SIDES OF THE SCANNER LID AT ALL TIMES
STEP 1 STEP 2 STEP 3
9.1 Press and hold the OPEN button to raise the lid until the
document gap is greater than the document thickness.
9.2 Insert the thick document
9.3 Press and hold the CLOSE button to lower the lid onto
the document until the motor noise stops automatically.
9.4 Now scan your document using the mouse, F9 or the
SCAN button as appropriate
9.5 Ensure that the scanner is not scanning or a document is being fed through the scanner
9.6 If a document is still in the scanner, support it while pressing the OPEN button and lift out the document
rather than using the FWD or REW buttons. This prevents the weight of the overhanging document levering
the trailing edge and causing it to be damaged or possibly damaging the scanner as it exits the rollers.

11. SWITCHING ON THE GX/GXT CCD SCANNER
SmartLF Gx/GxT can now be switched on. The liquid crystal text display (LCD) will
light up and after a few seconds will display the word ‘ Initialising’. After about 35
seconds or so the display will change to the words Scanner Warmup. After a
further 90 seconds the model number and firmware level of the scanner will be
displayed. Paper can be loaded during the Warm-up period.
If a document is loaded the display will change to the word ‘READY’
Start up Windows XP Professional / XP Home or Windows Vista (when released) on the connected computer that will
be used with SmartLF Gx/GxT. Wait for Windows to finish loading. FOR MORE DETAIL ON MINIMUM SPECIFICATIONS
FOR OPTIMUM SMARTLF GX/GXT PERFORMANCE SEE APPENDIX 1.
12. ESSENTIAL SCANNER OPERATING PROCEDURES
1. FOR BEST RESULTS ALWAYS SWITCH ON YOUR SCANNER FOR AT LEAST 1 HOUR BEFORE USING
2. ALWAYS NORMALISE YOUR SCANNER BEFORE SCANNING
3. PERIODICALLY CHECK YOUR SCANNER (WHEN WARM) FOR OPTIMUM STITCH ALIGNMENT
The SmartLF Gx/GxT scanner uses two fluorescent tubes to illuminate the scanning document. Like most fluorescent
systems the light intensity produced changes significantly during the first 2 minutes and can take up to 60 minutes to
reach full brightness and become completely stable. Also in a similar way to domestic fluorescent tubes the lamps in
the scanner have a limited useful life as they lose brightness with age and must be replaced - usually after about 1 year
of continuous operation. To offset the effects of tube ageing it is important to normalise (or calibrate) the scanner at
regular intervals. This will restore the maximum white levels obtainable across the scanner’s optical width even though
the actual brightness of the tubes may have decreased slightly or become uneven. Never expect full colour
performance from the scanner before it is properly warmed up or if it has reached its optimum temperature but not been
normalised for some time.
WHY NORMALISE?
If the scanner is not normalised regularly image brightness may be incorrect or appear uneven across cameras
(camera imbalance). If a recently normalised scanner still produces uneven scans it is probably not at its peak running
temperature and should be left to stabilise. The warming-up process may take longer in colder operating
environments.
Locate the Normalisation Target
The Normalisation and Stitch targets for SmartLF are
shipped in a single paper wallet inside the scanner box.
The normalisation target is the plain white sheet of
paper and must be used matt side down in the scanner.
DO NOT USE THE GLOSSY SIDE TO NORMALISE YOUR Gx/GxT SCANNER

How to normalise SmartLF Gx/GxT
From power-on always wait at least 5 minutes before normalising and preferably 1
hour for best results. Start the SmartLF Gx Utilities program from the program
folder or shortcut. If you have not already loaded Gx Utilities go to Section 16
‘Installing Scanner software from the Installation CD’. The first dialogue box to
appear contains the ‘Full Normalisation’ button.
Insert the Normalisation Target or any matte surfaced piece of clean white paper or
card into the scanner long edge first and allow it to load, then click the Full
Normalisation button to start the scanner normalisation process. The time taken
for the normalisation process varies between different width scanner models but
usually takes around 1-2 minutes.
Scanner switched off between scans in a constant temperature environment
Power on the scanner and wait for at least 5 minutes before scanning. For best results wait 1 hour before scanning.
For optimum results re-normalise before scanning.
Scanner switched on continuously in a variable temperature environment
The scanner can be used immediately but for best results the room temperature should have stabilised before using the
scanner and the temperature be the same as it was when the scanner was last normalised. If the temperature has
recently changed by more than +/- 5 deg. C wait 1 hour before re-normalising and scanning.
Scanner switched on continuously in a temperature-controlled environment
To return optimal performance the scanner should be re-normalised daily or at least weekly or when any variation in
image brightness or camera balance is noticed.
Changing the light tubes inside SmartLF Gx/GxT
The fluorescent light tubes inside SmartLF Gx/GxT are potentially dangerous and could cause injury if handled
incorrectly. Colortrac recommend that only an approved Colortrac trained technician should change the fluorescent
tubes as there is risk of electrocution if an attempt is made to change these without observing normal electrical safety
procedures.
Disposal of old tubes
Old tubes that are no longer required should always be disposed of in a responsible and ecologically friendly manner.
This usually means taking them to a recognised disposal company or agent. See the section on disposal at the end of
this manual.
AUTOMATIC & MANUAL STITCHING OF GX/GXT SCANNERS
After shipping and as part of the installation and commissioning procedure
the scanner should be checked for correct camera alignment. Before
checking or carrying out a stitch maintenance cycle (camera re-alignment)
the scanner should have reached room temperature and have been
switched on for at least 1 hour (see Section 21). If room temperature
changes permanently by more than 2 deg. C during regular scanning it may
be necessary to re-stitch the scanner to maintain optimal camera alignment.
To check for satisfactory camera alignment use the Automatic Stitch Target
(supplied) and ScanWorks or SmartLF and inspect a scan made at 600 d.p.i.
in greyscale. If the scanner needs attention start the Colortrac Gx Utilities
from the Windows program list (installed in Section 15) and go to the Utilities
area. Insert the Auto Stitch target (supplied) and press Auto Stitch.
Should the stitch target become damaged, lost or the automatic process fails
to work normally the Gx/GxT scanner can be re-aligned manually using any
suitable original. Pressing the Set Stitch button will start the interactive
manual re-alignment procedure.

13. THE WINDOWS XP .NET FRAMEWORK V2.0 ENVIRONMENT
The Colortrac SmartLF Gx/GxT software application has been created using Microsoft
.NET in accordance with current Microsoft development practice. This means the
connected computer running Microsoft Windows XP Home or XP Professional should
be upgraded if required by installing the .NET Version 2.0 Redistributable using either
the Colortrac CD or by following this link.
http://msdn.microsoft.com/netframework/downloads/framework1_1redist/
Although SmartLF Gx/GxT will work with Windows 2000 it is highly recommended that Windows XP with the latest
Service Pack (SP) upgrade and Windows Vista (when released) is used with SmartLF Gx/GxT scanners. Colortrac
advise that the .NET Framework be installed even if only using ScanWorks or CopySmart software options. SmartLF
Gx/GxT is simple to use and can be run on any computer connected to the SmartLF Gx/GxT scanner without a
license key.
NOTE: The belief is that in time .NET will become part of regular Windows and/or be included inside the regular Service Pack. See Appendix 3
in this document for more information on .NET Framework and how to check if it is installed on the computer you intend to use with SmartLF
Gx/GxT.
14. CONNECTING THE USB2 CABLE TO SMARTLF
With SmartLF Gx/GxT switched on, locate the included USB2 cable and plug
the smaller square end into the back of the scanner (see picture).
IMPORTANT: IF YOU ARE USING OTHER USB1.1 KEYS (DONGLES) ON THE SAME
COMPUTER ENSURE THAT SMARTLF GX/GXT DOES NOT SHARE THE SAME USB
INTERFACE INSIDE THE COMPUTER OR SCANNING SPEEDS MAY BE REDUCED.
DO NOT CONNECT SMARTLF GX/GXT TO THE PC YET!
15. PREPARING TO LOAD THE DRIVER
PLUG THE REMAINING END (FLAT SECTION)
OF THE USB2 CABLE INTO A SPARE USB2
INTERFACE ON THE COMPUTER- THE
DRIVER INSTALLATION WILL START
AUTOMATICALLY.
NOTE: At this point Windows XP will detect the new hardware and display the
following message in the System Tray area (normally the lower right-hand side
of the screen).
AT THIS POINT WINDOWS SHOULD DETECT SMARTLF GX/GXT AND AUTOMATICALLY BEGIN
RUNNING THE WINDOWS HARDWARE WIZARD. HAVE THE COLORTRAC SMARTLF GX/GXT
SOFTWARE INSTALLATION CD READY.
SMARTLF Gx / GxT SCANNERS MUST BE USED WITH A USB2 COMPUTER
INTERFACE. ATTEMPTING TO USE SLOWER USB1.1 INTERFACES WILL CAUSE
SMARTLF TO SCAN VERY SLOWLY AND POSSIBLE CALIBRATION MALFUNCTION
MAY RESULT. THE COLORTRAC GX UTILITIES USB2 SPEED CHECK CAN CHECK IF
YOUR USB2 INTERFACE IS OK

17. LOADING A DOCUMENT INTO SMARTLF GX/GXT
Normal thickness documents can be loaded into Gx/GxT center or right justified. Thick documents should always be
loaded into the scanner center justified. All documents should be loaded into the scanner face-down. Use the rollers
as a stop against which to square the document and wait for the scanner to take the document from you. If you need
to re-position the document use the STOP/REW button to withdraw the document.
CENTER SIDE
Colortrac SmartLF software (included as standard) is restricted
to scanning in industry standard paper sizes, fully automatic
size detect mode or full scan width with auto length detect
mode. SmartLF software does not allow the operator to
specify document sizes in mm or inches.
Auto Length (Max Width) allows the user to scan the full
optical width of the scanner whilst detecting the length of the
document automatically. As soon as the READY status is
displayed (usually after 35 seconds from switching on the

UNDERSTANDING THE CONTROLS OF SMARTLF
SmartLF Gx/GxT document loading is fully automatic. The document is detected using optical sensors
located near the center and at the side of the scanner nearest the control panel.
With two hands, place the document on the scanner with the longest edge (if possible) towards the scanner opening.
The document is now pushed against the stationary rollers, ‘squared up’ and held in this position. The display will
change to ‘LOAD’ as SmartLF Gx/GxT detects the media. After approximately one second SmartLF Gx/GxT will start
to load the document. After the document is loaded the display will return to ‘Ready’
When a document is loaded and the SmartLF software (or ScanWorks and CopySmart optional software) is running,
either the software icons or the scanner panel buttons can be used to start and stop the scanning process. The panel
display will show the word ‘Scanning’ just before and during movement of the document through the scanner.
REMOVING A LOADED DOCUMENT/ CORRECTING A SKEWED DOCUMENT
Pressing the red STOP / REWIND button on the Gx/GxT panel during or after a document has been
loaded will REWIND the document. The document will rewind for as long as the button is held down.
This is useful when a document skews slightly, loads awkwardly or needs to be rotated to present a
better or longer side to the scanner.
A document can be rewound at any time. The STOP button may be pressed during
display of the ‘Abort load?’ message.
ADVANCING (FORWARD FEEDING) THE DOCUMENT
After a document is loaded pressing this button will forward advance the document. SmartLF Gx/GxT will
move the document for as long as the button is held down.
EJECTING THE DOCUMENT
After a scan has completed and where the software is instructed to hold the document, this button can be
used to eject the document from the rear of the scanner.
STOPPING SMARTLF GX/GXT WHEN UNDER PROGRAM CONTROL
STOPPING SMARTLF GX/GXT
SmartLF Gx/GxT During scanning, press STOP / REW to stop the scanner and abort a scan. The
display will show the message ‘Rewind?’ At this point the operator can press
STOP / REW again to rewind the document or do nothing to have the document
stay at its current position. A loaded document can be rewound at any time using
the STOP / REW button 1
SmartLF Toggling2 the software FILE, COPY or EMAIL icons will stop an operating scanner
Toggling2the panel STOP / REW, SCAN and COPY buttons will stop the scanner

document will be ejected. If ScanWorks has been set for Do nothing the document
will remain in the scanner.
Press the LOAD/FORWARD or STOP / REWIND button to remove a document.
NOTES: 1.The behaviour of the scanner will depend on the software driving the scanner and how it has been configured.
2. Toggling means pressing the same function button a second time i.e. once for ON and again for OFF.
18. WINDOWS XP AND PANEL CONTROL OF THE SCANNER
The XP Windows Image Acquisition Device Driver Interface (WIADDI) supports custom scanner interfaces allowing
SmartLF Gx/GxT hardware to start key program operations. The SmartLF Gx/GxT scanner SCAN and COPY buttons
can be used to start and stop these primary software functions from the scanner control panel instead of, or in
conjunction with the software. They operate with the standard SmartLF, ScanWorks and CopySmart software but only
with the Windows XP operating system. To set up the panel buttons go to the Windows XP Control Panel and set the
properties for ‘Scanners and Cameras’ to TAKE NO ACTION as below.
IMPORTANT: TO START SCANNING OR COPYING FROM THE SCANNER PANEL WHILST USING SMARTLF
S/W, THE RELEVANT BUTTON ON THE SCANNER MUST BE PRESSED FOR AT LEAST 0.5 SECONDS
19. TESTING AND SCANNING USING ONLY THE DRIVER (WIA)
After the SmartLF driver has been installed Explorer should
show the scanner (must be powered and connected) under
Scanners and Cameras. If it is not visible click Scanners and
Cameras in the Control Panel.
By right-clicking the Explorer entry then clicking Scan or Get
picture using Scanner Wizard the user can force the scanner
to scan to file.
Alternatively using the Select TWAIN source and Acquire
options from the File pull-down of most Microsoft scanner-
friendly applications the SmartLF user can scan directly into the
application (no file necessary). See screenshot.
NOTE: The scanner WIA driver (Jan 2007) is not yet compatible
with Twain/ WIA acquire software expecting automatic switching
to WIA.

the target Windows printer where the copy will be printed first using the I-button.
EMAIL - To have SmartLF Gx/GxT scan to e-mail press the envelope in the Email button. This requires a configured
email client to be set up first, e.g. Outlook Express.
NOTE: For fragile originals SmartLF Gx/GxT can be slowed down using the Quality
slider accessed from the i-box in the top left corner of the SmartLF interface. As soon
as the required function is selected SmartLF Gx/GxT begins to scan the document
loaded in the scanner or waits for the document to be loaded. SmartLF Gx/GxT will
display the animated icon showing a document being loaded into the scanner.
PRESSING THE RUNNING FUNCTION ARROW ICON STOPS SMARTLF GX/GXT
SmartLF Gx/GxT can also be controlled from the scanner’s control panel by pressing

SMARTLF USES INTELLIGENT FILE OVERWRITE/ RENAMING
If a file already exists inside the computer directory with the
same name as the name the operator is about to use for a
new scan, SmartLF will try to assist.
-If the file does not contain numerical information
SmartLF pre-selects (blocks) the name part of the file
ready for the operator to type in a new name.
-If the file contains numerical information SmartLF pre-
selects ONLY the numerical part ready for the operator to
type in a new number.
AUTOMATIC DOCUMENT SIZING
SmartLF Gx/GxT scanners will detect the size of a loaded document if there is
sufficient gray contrast between the edges of the document and the inside of the
scanner. On occasions automatic size detect may not be successful.
If the document is undersized when using auto-detect select a paper size larger
than the document to be scanned and use the crop feature in the section below to
reduce the size of the image before re-saving it.
NOTE: The effectiveness of Auto Size can be affected by the type of media loaded
in SmartLF Gx/GxT. For example transparent or non-square media may fail to
auto size correctly.
THE SMARTLF PREVIEW WINDOW
CROPPING IN SMARTLF
Use SmartLF CROP IMAGE to select an area of the image for scanning to
file, to the Windows printer or email.
Pressing the CROP IMAGE icon on the Preview toolbar places a green crop
square onto the currently displayed image. Use the grips at the corners to
resize the crop boundaries. Clicking and holding the mouse button down on
the centre of the square will move it across the image.

COPYING FROM SMARTLF
SmartLF software uses any standard Windows printer driver for copying.
The number of copies can be controlled from the COPY button by clicking on
the + and – icons.
The print quality of the copy is controlled from the Windows driver Properties
dialogue in the normal way.
SmartLF will copy all images at 1:1 i.e. no scaling will take place unless set
up in the Properties dialogue of the windows printer driver.
DOCUMENT SIZE MARKINGS ON THE SCANNERS
To scan a non-standard size of document select a
document size that is larger than the document you
need to scan. The SmartLF software will allow
‘cropping’ (removal of unwanted square edges
from) of the image before saving it to computer. If
the document is rectangular the auto-sizing option
will detect the width of the document and determine
the length of the document automatically.
NOTE: Auto-sizing may not be 100% effective for all types of document.
TRANSPARENT AND OPAQUE ORIGINALS
SmartLF will set-size scan and auto-size scan, clear and opaque media. Clear acetate drawings will often produce
betters results when used with a white backing sheet. A scanning wallet with an integral white backing sheet can be
effective. Auto-size detection may not work every time and may depend on the calibration quality of the scanner.
DOUBLE-SIDED ORIGINALS
Originals that have information on both sides can sometimes benefit from being scanned with a black backing sheet
placed behind the image to be captured. Wallets with a black backing surface and clear acetate front can be useful.
THICKNESS OF MEDIA COMPATIBLE WITH SMARTLF GX/GXT
SmartLF Gx/GxT is compatible with many types of media including synthetic, polyesters, Mylar and general office
tracing and inkjet papers. The accuracy of SmartLF Gx/GxT is valid for media up to 0.8mm thick and may vary
depending on the operating environment. With SmartLF GxT the document thickness limit raises to 20mm.
STIFFNESS OF MEDIA COMPATIBLE WITH SMARTLF GX/GXT
SmartLF Gx/GxT will handle all regular media of 60g/m2and above. Paper below this weight can have very low
stiffness (for example some newspapers) and these may become creased in the scanner unless protected inside a
suitable scan wallet. Wallets can be readily obtained from stationery suppliers or improvised by folding some clear
acetate and placing the document into the fold. Best results are obtained by loading the wallet fold-first into the
scanner.
21. SCANNER MAINTENANCE
SmartLF Gx/GxT will need some occasional glass cleaning and white calibration (normalisation) maintenance. For
best results follow the instructions below.
GLASS CONTAMINATION, SCRATCHING AND REPLACEMENT
The single SmartLF Gx/GxT scanner CIS glass cover is chemically treated and should resist scratching from paper
clips, abrasive dust and staples but Colortrac recommend that the operator take all reasonable steps to ensure that
scan documents are clean and free from metallic appendages and abrasive dust or other contaminants. The scan
glass should be cleaned with a low-smear, high quality glass cleaning product and a clean lint-free cloth.

Colortrac SmartLF Gx/GxT Range Installation and Operating Instructions
PAS161 P/N: P002168 Colortrac Ltd © 2008
19
If streaking of the scanned image is seen after careful inspection and cleaning of both
sides of the scanner glass some dirt may have been incorporated into the normalisation
at the last calibration. The scanner should then be re-normalised using the matte side of
the calibration target making sure it is clean and free from deep creases. NOTE: The
scanner must have reached its normal operating temperature prior to recalibrating. See
section 21 below.
In the event of the glass becoming badly scratched and affecting scans a replacement
can be ordered from your Colortrac supplier. Replacing the glass will not affect the
alignment or stitching of SmartLF Gx/GxT and does not require a technician.
If vertical lines still occur through the scanned image it may mean that dust or dirt has
found its way into one of the Digital Camera Unit modules. You can attempt to remove it
but you must follow the instructions below very carefully or an EXPENSIVE REPAIR MAY
BECOME NECESSARY.
1. AVOID the use of canned air or aerosols of compressed air if at all possible as these rarely contain only clean air.
If you must use canned air -
Ensure you use a brand intended for optics and not one for general electronics. Commonly available
products often contain propellants and produce other residues that will dry and contaminate the surface
you are trying to clean.
Never shake the container before use as this will mix the propellant with the ‘air’.
Always try to keep the container upright when in use.
Always use strong bursts - DO NOT progressively squeeze the trigger, as this may cause nozzle splutter.
Always start the jet away from the optics first to clear the nozzle before directing onto the optics.
Always spray test the product on some old dark glasses or dark shiny plastic to check for signs of residue.
Be aware that an almost empty can draw propellant and other residue into the air stream.
2. TRY IF POSSIBLE to find a hand air pump without a tip brush similar to the type used for cleaning cameras.
Various brands of these are available but a particularly good example is the Rocket Air Pump obtainable from good
camera accessories shops or on-line. These devices use an inlet valve that prevents dirt from being sucked back
into the bulb between blasts and supply clean, contaminate-free air. Do not allow the nozzle to physically touch
the optics.
3. AVOID using brushes or general brand wipes as these can scratch the optics.
4. AVOID touching any of the components with the fingers, as this will leave a grease film and cause blur.
5. AVOID the use of acetone, ethanol, alcohol and other solvents unless they have been formulated specifically for
cleaning optical surfaces. WARNING! Most of these solvents are hazardous to health.
6. If you suspect the mirror, lens or CCD to have been coated with a residue (e.g. from canned air or other cleaning
agents) we recommend you contact your Colortrac agent immediately.
Other serious maintenance issues such as electronic or a suspected internal mechanical failure should always be
referred to your approved service agent for diagnosis and repair.
22. FIELD UPGRADE OF SMARTLF GX/GXT TO A HIGHER MODEL
If your scanner is a model Gx/GxT m (mono only) or Gx/GxT c (low speed color) SmartLF Gx/GxT it can be upgraded
by purchasing one of the three SmartLF Gx/GxT Field Upgrade products available. The upgrades are ordered by
Product Code.
The process for model upgrading is as follows:
STEP 1 – GENERATE THE UPGRADE FILE USING THE SMARTLF GX/GXT SERIAL PROGRAM
1. Confirm that SmartLF Gx/GxT is connected and working (i.e. driver installed properly)
Picture: Removable / replaceable
glass cover of the Gx/ GxT
scanner

2. From the SmartLF Gx/GxT distribution CD locate the SmartLF Gx/GxT serial.exe program which is inside the
Scanner upgrade folder (itself inside the Utilities folder). You may need to alter your Explorer viewing options to
see the full .EXE extension of this file.
3. Double-clicking “SmartLF Gx/GxT Serial” will
retrieve the Scanner model number from the
attached SmartLF Gx/GxT scanner (in this case a
Gx/GxT m).
4. In the Serial Number box type in the 8-digit number
printed on the label attached to the back of the
scanner.
5. Now select the model you wish your unit to be
upgraded to using the Desired Model scroll bar
6. Press the ‘Record Serial Number’ button to create
the upgrade file.
STEP 2 - SEND THE UPGRADE FILE WITH YOUR ORDER AND THE PRODUCT CODE YOU REQUIRE TO
YOUR SMARTLF GX/GXT SUPPLIER TO OBTAIN YOUR UPGRADE PROGRAM
(The upgrade options for a Gx/GxT 42 are provided as an example – different part numbers will apply to the Gx/GxT 25)
Product Code Upgrade from Upgrade to
P005043 42m 42c
P005044 42m 42e
P005045 42c 42e
STEP 3 – UNPACK THE UPGRADE PROGRAM
7. The supplier will send you a file that has the serial
number of the scanner to be upgraded as part of its
name. Unpack this file to a temporary directory and
run the program named “SmartLF
Gx/GxTModelUpdate.exe”. Click the button labelled
‘Update Model’. This will then upgrade the
connected SmartLF Gx/GxT scanner and display the
words, ‘Scanner firmware updated OK’ on the
scanner display.
8. Exit the program and then turn SmartLF Gx/GxT OFF. Wait for 5 seconds before turning the scanner back ON
again. Check the scanner display and verify that SmartLF Gx/GxT is displaying the model type consistent with the
upgrade process just carried out i.e. that the upgrade has been successful.
23. APPENDIX 1 - COMPUTER REQUIREMENTS FOR SMARTLF GX/GXT
The minimum computer specification needed to achieve the stated SmartLF Gx/GxT performance is as follows:
Operating system: Windows XP or Windows Vista (see note 4)
Processor: At least 2.8GHz, DUAL CORE (AMD), CORE-DUO (Intel) or HT (Hyper Threading) processor
Memory: At least 512MB RAM
Data port: A USB2 compatible interface (see note 5)
