Problem

Possible Causes and Remedies

Scanning: The colors in my scan are not correct in relation to the
original document

Please carry out a calibration of the scanner. Calibration adjusts the color settings.

1. Thoroughly clean the scanning area. See Cleaning the scan area for instructions.

2. Run the calibration wizard and follow the steps described in the section Scanner
Calibration in this guide.

3. Be sure to choose Full Calibration

Copying: The colors in my printed output were not copied correctly
in relation to the original document

1. Make sure that the Media setting matches the media loaded in the printer. If they
are wrong, correct to the right media.

2. If you have used the correct Media setting in the Copy settings, you should
recreate a new media profile:

a) Thoroughly clean the scanning area.
b) Run the calibration wizard and steps as described in the section Full

Calibration in this guide. Be sure to choose full calibration.

Now create a new Media profile:

c) Select -> Printer
d) Select Media Profile to start the media profile wizard to create a new

media profile.

Follow the instructions on your screen.

Entire image is not scanned

Make sure that you are loading the original correctly:

1. Be sure to align the center of the original with the scanner center arrow mark.

2. Load with the printed side face up.

Page | 13

Problem

Possible Causes and Remedies

Large empty areas on both sides of the image

Go to the Area option in your scan settings before pressing the green go button.

 The All setting means that the scanner will disregard the original’s size and capture

the whole scanner width which will add white space on both sides of the document.

 Select Auto if you only want to scan the width of the loaded document.

One or more thin vertical lines (in the direction of paper feeding)
show up in the scanned image, but not in the original document.

This is often caused by an unclean glass plate. Even a single spec of dirt in the wrong
spot on the glass plate can cause a streak along your entire scan. To remedy:

1. Clean your glass plate and rollers as described in this users’ guide under Cleaning.

2. Most of the dirt on the glass plate comes from the documents that are passed
against it. Wipe the document clean with a dry lint-free cloth before feeding the
document into the scanner.

3. If the problem persists after cleaning, calibrate the scanner. The scanner may have
memorized dirt specs and you will need to recalibrate after removing the dirt.

4. If the problem persists after cleaning and calibration –Check the glass plate for
scratches. A damaged glass plate should be replaced. Obtain a new glass plate
from your service provider. Follow the steps in the user’s guide to replace the glass
plate with a new one.

5. A damaged calibration sheet can also cause streaks. Obtain a new sheet and
recalibrate the scanner

Page | 14

3.4 Problems with the scan result

Problem

Possible Causes and Remedies

Whole image not scanned

1. Check in your scanning application that your size settings are either for Auto

detection or correspond to the size of the whole original.

2. Check that you are loading the original correctly from the scanner’s right side.

One or more thin vertical lines show up in the scanned image, but
not in the original drawing.

This is often caused by an unclean glass plate. Even a single spec of dirt in the wrong
spot on the glass plate can apply a streak along your entire scan. To remedy:

1. Clean your glass plate as described in this users’ guide.

2. Most dirt on the glass plate is introduced by the documents. Wipe clean the

document with a dry lint-free cloth before feeding the document into the
scanner.

3. If the problem persists after cleaning, calibrate the scanner. The scanner may

have memorized dirt specs and you need to recalibrate after dirt-removal.

4. If the problem persists after cleaning and calibration –Check the glass plate for

scratches. A damaged glass plate should be replaced. Contact your service
provider for information.

5. A damaged calibration sheet can also cause streaks. Obtain a new sheet and

recalibrate the scanner.

3.5 Troubleshooting Sequence

This is a suggested Troubleshooting Sequence and will work in
most cases. There are always some grey zones, especially if the
problem is related to image quality.

Page | 16

3.6 Image Quality Problems.

3.6.1 Banding Problems.

 Bad/no grey balance calibration (CIS module to

module match).

 Running WIDEsystem calibration should resolve

this problem in most cases.

3.6.2 Crumpled Paper or folds

 Scanning originals that have folds or are

crumpled on CIS scanners is often confused as
a defect in the scanner, where it is actually a
limitation of the technology used. Due to the
very short distance from the sensor to the
surface of the original, referred to as the “Focal

Length”, if the document does not stay in

contact with the glass plate then it is very likely
to be out of focus.

Page | 17

3.6.3 Dust Problems.

 There are image quality problems that are not

related to HW errors. These could be due to
insufficient cleaning, bad calibration or
limitations in the CIS technology. Streaks
running in the scan direction could be caused
by dust on the surface of the CIS module.

 Streaks that run in scan direction, that are color

independent or a lighter shade of the color, are
often related to the calibration. Check the
calibration sheet for scratches, clean the glass
plate and check the surface of the CIS for any
dust before running the WIDEsystem
calibration.

3.6.4 Stitching Problems.

 Typically, the scanner simply needs to be

calibrated, either because the parameter block
has been erased, the scanner has never been
calibrated or the scanner has been moved
around. If re-calibrating the scanner does not
correct the stitching problem then check to be
sure the document is lying flat against the glass.

Stitching problem between 2 CIS modules.
