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.
