2.1 IMAGE EXAMPLES
Original
Scanned Image
1. Bad image quality with washed out or
incorrect colours is normally down to the
scanner needing normalisation.
Insert the white target into the scanner with
the matt side face up.
Open the Utilities program, and on the front
page, press Full Normalisation and allow the
process to complete.
2. When the image between 2 CIS points has a
step, it is because the scanner needs to be
stitched, an electrical adjustment for making
the scanner see an image equally across all
the CIS arrays.
Open the Utilities program and stitch the
scanner as described in the service manual.

3. Fine lines down the image can be either dirt1or a scratches2on the glass or dirt being picked up
from the paper tray and dragged through. If the line is contineous through the scan, clean the glass
and re-normalise. If it starts and appears to disapear further down the scan, clean the paper tray
and try again. Scratched glass needs replacing.

Black Area
Black Section
4. A black area in an image can be down to CIS, cable or Main Board. A black area3completely over
one CIS can be either the CIS, the cable or the main board, where as a black section4of a CIS is
more likely to be the cable and / or CIS; the main board is not as likely. Easiest thing to try first, in
all cases, is the cable. Re-seat it at the Main Board end, making sure there are no broken cores or
damage visible. A CIS can be swapped within the CIS Mounting Bracket to check to see if the
problem is a CIS, or to move the faulty CIS to the end of the scanner if the customer does not use
the full width of the scanner. The Main Board is the next easiest thing to swap to see if the problem
goes away. Refer to service manual for procedures.
5. Early versions of the software created completely black scans of a 0mb file size. This was a bug in
the software. Make sure the software is up to the latest version from the Colortrac website:

Distorted Start of Scan
Colourmatch
6. A distorted image at the beginning of a scan,
or at the point where the scanner has stopped
and started during a scan, is down to the
Motor Drive Pulley being loose on the motor,
or the main timing belt being loose.
See service manual procedures.
7. Colour differences between 2 CIS can be
down to the scanner needing normalisation,
or the glass or paper hold down roller not
seating properly over the CIS, make sure
there is correct and even gap between the
paper hold down rollers and glass. Some
times the colour imbalance can be down to
the tolerance between 2 CIS, which is
common in all CIS scanners.
8. Some times image problems, particually if the image looks currupt and completely unrecognisable,
can be solved by resetting the scanner. Use the "Reset Flash to Factory" in the passworded area
of the utilities program to do this, making sure you record the motor speed and stitch values before
running this process, and re-insert them again afterwards. Normalisation completes the process.
