to “Feed Module” in Chapter 5, Maintenance).

7-2 A-61159 May 2002

Color Image Quality Color image quality is highly subjective because people perceive color

images differently. Here are some things to consider when scanning
in color:

• The differing colo r outputs of scanners, printers, and monitors can
affect the perception of the scanned document.

• Computer monitor displays and printer out put can vary from
model to model, and from manufacturer to manufacturer. An image
may be acceptable on one monitor and unacceptable on another.

• Area lighting (fluorescent , natural, incandescent) can affect
color perception.

• The appearance of a colored area within an image can be perceived
differently, based on what surrounds it.

• The characteristics and conditi on of a document can have an impact
on color consistency.

• Color requirements may differ between environments (e.g., in a
business document environment, images are generally viewed on a
monitor, whereas in a “print on demand” environment, scanned
images are printed).

To ensure that your scanner is delivering the best image:

• Clean the scanner. Contamination within the scanner
degrades image quality. (Refer to Chapter 5, Maintenance,
for cleaning information.)

• Calibrate the scanner at least once per week.

• Make sure that the calibration target is clean and unwrinkled.

• Change the color table. Individual results may vary.
The default color table provides robust image quality for a wide

range of input and applications. However , additi onal specialized color
tables are available from within the Diagnos tic Software (for TWAIN
only) for varying document types and applications needs, such as
photographs, text for OCR, and so forth.

NOTES:Calibrate the scanner before you change the color table.

Color scanning is available only on the Color Scanner 3590C
and Color Scanner 4500.

A-61159 May 2002 7-3

Error Log The error log in the Diagnostic Software contains information

about any errors that have occurred during scanner operations.
For more information about the error log, refer to “Error Log” in
Chapter 6, Diagnostics.

NOTE: For more information about the Diagnostic Software features,

refer to the online help in the software.

Testing the System Two brief tests can be run to check scanner performance: self-test and

scan system test.

• A self-test checks the image processing hardwar e in your scanner.

• A scan system test checks the scanner’s ability to capture an image.

For more information about these test s, r efer to “Test ing the Syst em” in
Chapter 6, Diagnostics.

NOTE: In order to perform a self-test or scan system test, the

Diagnostic Software must be installed on your PC.

7-4 A-61159 May 2002

Problem Solving Occasionally, you may experience a problem with your scanner.

In many cases, you can easily fix the problem yourself. Try the
solutions in the order in which they appear. To perform suggested
maintenance or diagnostic tasks, refer to Chapter 5, Maintenance,
or Chapter 6, Diagnostics.

Problem Possible Solution

The scanner will not scan/
feed documents

Make sure that:

• the power cord is plugged in and the power is on.

• the side access door and pod are completely closed.

• the printer access door (Scanner 3520DP or Color Scanner
4500DP) is completely closed.

• the proper power-up sequence w as followed and the software has
enabled scanning.

• the top green indicator light on the fr ont panel is on.

• documents are making contact with t he feed module.

• the height of batched documents is less than:

 15.2 mm (0.6 in.) on a scanner using the Feed Module 150.
 25.3 mm (1.0 in.) on a scanner using the Feed Module 250.

• for documents stac ked nea r the max imum heights listed above, you
position the batch 12.7 mm (0.5 in.) away from the baffle housing.

• documents meet specificati ons for size, weight, and height of
batched documents, etc.

• for thicker documents, you press the gap rel ease button
during feeding.

• you check the feed module and separator roller for signs of wear,
and replace these parts if necessary.

• you try to scan a document using the Diagnostic Software.

Image quality is poor or
has decreased

Make sure that:

• the lamps have been on at least three minutes.

• the scanner is calibrated (refer to “Calibrating the Scanner” in
Chapter 6, Diagnostics).

• the imaging guides are clean (refer to “Imaging Guides” in Chapter
5, Maintenance).

• you use the Diagnostic Software to scan a document using different
settings to see if image quality improves.

If unsatisfactory image quality persists, or if the scanner fails
calibration, replace the lamps (refer to “Lamps” in Chapter 5,
Maintenance). Be sure to calibrate the scanner after installing the
new lamps. Make sure that the new lamps have been on at least
three minutes before you calibrate.

7-8 A-61159 May 2002

Problem Possible Solution

The first few scanned
images are very dark

Both green indicator
lights on the front panel
are flashing

The amber indicator light on
the front panel is flashing

The red indicator light
on the front panel is on
or flashing

Calibration has failed Make sure that:

Make sure that the lamps have been on for at least 30 seconds, then
scan the images again.

The 48-megabyte image buffer is full. Stop scanning momentarily and
wait for the host computer to “catch up” with the scanner output. This
will free up space in the image buf fer. Make sure that there are no
problems with your scanning software.

Most likely, a document jam has occurred in the paper transport area.
Refer to “Clearing Document Jams” in this chapter.

If the red indicator is on, a failure (power-up, lamp, hardware,
software, accessory, calibration, or multifeed) has occurr ed.

If the red indicator is flashing, an error (for example, a lost or
corrupted image) has occurred.

Refer to “Error Log” in this chapter, then access the Diagnostic
Software and check the error log for informati on.

Refer to the appropriate chapter (Chapter 5, Maintenance, Chapter 6,
Diagnostics, and/or Chapter 7, Troubleshooting) to correct the
problem identified in the erro r log.

• the lamps have been on at least three minutes.

• you are using a proper calibration t arget. Use a clean, blank sheet
of white paper with a matte surface (not glossy). The calibration
target should be wider than the document s you are scanning. It is
best to use the 30.5 cm (12 in.) square calibration tar get available
from Kodak. You may use a differ ent target if it meets the conditions
above, but the target must be at least 20 cm (8 in.) in length.

• the imaging guides are clean (refer to “Imaging Guides” in
Chapter 5, Maintenance).

• the transport area is clear of obstructions.

Try calibrat ion again. If calibrati on fa ils agai n, replace t he lamp s (ref er
to “Lamps” in Chap ter 5, Maintenance). Be sure to calibrate the
scanner after install ing the new lamps. Make sure the new lamps have
been on at least three minutes before you calibrat e. If calibration still
fails, request assistance.

“False” paper jams
are occurring

A-61159 May 2002 7-9

If the amber indicator light on the front panel is flashing, and no paper
is jammed inside the scanner, make sure that the paper transport
sensors are clean (refer to “Paper Path and Sensors” i n Chapter 5,
Maintenance). Very dirty sensors can cause a false paper jam to
be indicated.

Problem Possible Solution

Documents are jamming Make sure that:

• the output tray and guides are adjusted for the length of documents
being scanned.

• all jammed documents have been removed from the paper
transport area.

• documents meet specificati ons for size, weight, and height of
batched documents, etc.

• the sensors, and the reflective tape opposite th e sensors, are clean.

• the separator roller access cover is properly seated.

• the separator roller and feed module are clean and
properly installed.

• the paper transport rollers are clean.

• the imaging guides behind the side access door are
properly installed.

Documents are skewed
during scanning

35.6 cm (14 in.) or longer
documents are not feeding
or are jamming

Documents are multifeeding Make sure that:

Make sure that:

• the feeder guides are adjusted to fit the documents being fed.

• documents are being fed perpendicular to the feed module.

• documents are being fed in the center of the feeder, with the full
width of the feeder rollers making co ntact with all documents.

• the feed module, separator roller, and paper transport rollers
are clean.

Make sure that:

• the input tray extender is opened to provide support for
long documents.

• the output tray is adjusted for the length of the documents
being scanned.

• the output tray is installed properly under the scanner. The output
tray’s center rib must be loc ated in the center slot u nder the scanner
so that you can easily slide the tray in or out.

• the leading edges of all batched documents are centered under the
automatic paper feeder so that each document comes in contact
with the feeder rollers.

• the feed module and separator roll er are clean and not worn.

• documents with an unusual texture or surfa ce are fed manual ly.

7-10 A-61159 May 2002

Problem Possible Solution

There are frequent multifeed
detection errors

The output tray cannot be
adjusted in or out

Roller marks appear on
documents after scanning

The first few color images
are very bright

On the Color Scanner
3590C, the back side of
documents does not
appear in color

On the Color Scanner
3590C, the patch docum ent
is not detected; therefore,
the scan mode does not
change between color and
bitonal (black and white)

Make sure that:

• multifeed thickness has been calib rated.

• the pod and side access door are completely closed.

Make sure the output tray is installed prope rly under the scanner.
The output tray’s center ri b must be located in the center slot under
the scanner so that you can easily slide the tray in or out.

Clean the feed module rollers, separa tor roller, and drive rollers.
Refer to Chapter 5, Maintenance.

Make sure that the lamps have been on at least three minutes, then
scan the images again.

This is normal. Color scanning on the Color Scanner 3590C is for the
front side of documents only.

Make sure that:

• patch detection is enabled in your software.

• the patch document meets specifications.

For more information, refer to “Switc hing Scan Modes” in Chapter 4,
Using the Scanner.
