scratched and affecting the scans, replacements can be ordered from your Colortrac supplier. Replacing the glass

covers will not affect the alignment or stitching of SmartLF Cx in any way and is not a technician graded task.

(More serious maintenance issues such as electronic or a suspected internal mechanical failure should be referred to

your approved service agent for diagnosis and repair).

CX UTILITIES - AUTOMATIC & MANUAL NORMALISATION OF SMARTLF CX

SmartLF Cx by default is set for Automatic Normalisation.

Run the Cx Utilities program to check the normalisation setting

for SmartLF Cx. The default time interval between calibrations is

set for 1 hour during scanner manufacture but can be increased

or turned off completely by the user.

Normalisation will occur only when a scan is requested AND

• the normalisation time period has been reached

• or the true time is just after the hour (Every Hour setting)

Automatic normalisation needs no target or user intervention

and takes approximately 25 seconds to complete.

SmartLF Cx informs the operator that a normalisation is taking place by

displaying the word ‘Scanning’ on the scanner display panel

Why normalise?

Contact Image Sensors (CISs) can be sensitive to variations in room temperature so Normalisation is used to maintain

optimum image quality for SmartLF Cx. For best results SmartLF Cx should be normalised regularly.

Manual Normalisation (Full Normalisation)

Manual normalisation is useful where the scanner is being operated in

extremes of temperature. First disable the Auto Normalisation by running

Cx Utilities and changing the period to Never.

Insert a piece of clean white paper or card approximately 1067mm (42”) x

508mm (20”) into the scanner long edge first and allow it to load. Now

press the Full Normalisation button to start the scanner normalisation

process.

NOTE: SmartLF Cx only has one calibration memory. This means that if a

manual Normalisation is carried out with white paper the Auto

Normalisation period must be changed to Never. If this change is not

made the scanner will replace the manual normalisation with the automatic

normalisation when it next occurs.

ESSENTIAL CALIBRATION INFORMATION

 SmartLF Cx will carry out an overdue normalisation immediately after a scan is requested.

 Automatic normalisation will delay a scan by approximately twenty-five (25) seconds. This is normal.

 If a manual Normalisation is to be used, always change the Automatic Normalisation Period to Never
