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.
