Introduction
The EPSON® Scanning Utilities let you perform the following
functions with your EPSON scanner:
Calibrate your scanner to your monitor and your printer
Capture scanned images from within your application
Automatically locate, expose, and scan an image
Adjust individual settings and preview the effects before
you scan
Choose single- or triple-pass scanning
Save and reuse scanning settings that work well in your
environment
Take advantage of the multipage scanning feature available
with scanners that have an automatic document feeder
(ADF)
Take advantage of the text enhancement technology built
into some EPSON scanners.
The EPSON Scanning Utilities are composed of two integrated
main programs: EPSON Scan! II and EFSON TWAIN. EPSON
Scan! II calibrates your scanner with your monitor and color
printer to produce images in colors that closely match the
originals. It can also capture images and then save and export
them in a variety of file formats.
EPSON TWAIN is the interface between most of your software
and your scanner. TWAIN has two screens: easy and
advanced. You can access either screen from within any
software that supports the TWAIN standard or from EPSON
Scan! II to take advantage of your scanner’s features.

Chapter 2
Calibrating Your System
Sometimes the colors of your original image do not match the
colors you see on your screen and in the final printed output.
This is because of the different color processes your scanner,
monitor, and printer use to produce color.
The scanner and the monitor both create a range of colors by
adding red, green, and blue (RGB) in different proportions and
intensities (an additive color process). Printers, on the other
hand, produce colors by combining cyan (C), magenta (M),
yellow (Y), and black (K) inks (CMYK) to create the desired
hues. This is a subtractive color process.
When you print a scanned image, the image goes through both
the additive and subtractive interpretive processes to acquire
colorthe first when it is scanned, and the second when it is
printed on your color printer. As a result, the printed colors
may not match the colors in the original.
Calibration allows you to fine-tune your scanner, monitor, and
printer to produce colors that are very close to those in the
originals. Use the procedures in this chapter to:
Calibrate your monitor to your scanner
Calibrate your printer to your scanner
Use the resulting calibration profiles when you scan an
image.

Calibrating Your Monitor to Your Scanner

Note:
If your scanner does not support Text Enhancement Technology, the

Modifying the Destination
The Destination dialog box allows you to define different
resolutions for each destination output device. You can also use
it to modify, add, or delete a calibration profile for your output
device.
To modify the Destination, click the Destination button. You
see the following dialog box:
Selecting resolution settings
Use the Resolution pull-down menus to select resolutions that
produce the best results for your image type and output device.
You can select one resolution for line drawings and halftones
and a separate resolution for photographs.
The best resolution setting for your image depends on the type
of image you are scanning and your final output device. The
following table shows the best scanning resolutions for most
needs.

The higher the resolution you select, the larger the resulting
image file. For example, an 8.5 x 11-inch photograph scanned
at 300 dpi can produce a 24MB file. The same photograph
scanned at 72 dpi creates a file of only 1.36MB. Large files take
longer to process and print. Consider the limitations of your
computer and hard disk drive when you select a resolution. To
keep file sizes manageable, select the lowest possible resolution
that gives acceptable quality.
Tip:
As a rule of thumb for any image except line art, use scanning
resolutions that are one third of your output resolution. For
example, use a scanning resolution of up to 110 with a 300 dpi
laser printer and up to 170 with a 600 dpi laser printer. For
EPSON Stylus
printers,
choosefrom 100 to 240 dpi for
720 dpi output and from 100 to 150 dpi for 360 dpi output.
Tip:
For printing on a commercial printing press, multiply the
lines per inch (lpi) the press prints by 2 to determine the
scanning resolution. For example, if the lpi is 150, scan at
300 dpi. (lf the resulting file is too large, try multiplying the
lpi by 1.5 to determine the scanning resolutibn.)
Tip:
If you plan to enlarge an image when you print it, scan it at a
higher resolution than you normally would.

Selecting calibration profiles
Use the Calibration pull-down menu to select a predefined
calibration profile or create a custom one. TWAIN can then use
the profile as it scans to create the best quality image.
EPSON TWAIN Scanning Utilities provide many predefined
printer calibration profiles, including those for the EPSON
Stylus color printers, as listed below:

An error in the scanner or a paper jam in the Automatic Document
Feeder caused an error message.
Remove the jammed paper or reset the scanner to clear the
error condition; then try scanning again.
The Sharpness setting is grayed out in the Image Controls dialog
box
Your scanner does not support the Sharpness feature.
The Document Source setting is grayed out in the EPSON TWAIN
screen.
This is normal. You must first install an optional Automatic
Document Feeder or a Transparency Unit to be able to select
these as your Document Source.
You are using Adobe® Photoshop® 2.5.1
and the Color Drawing
and Color Halftone options are grayed out in the Image Type
pull-down menu.
This is because Photoshop 2.5.1 can scan only in 1, 8, or 24 bits
per pixel, so you cannot use these M-bit per pixel Image Types.
The Preview icon is grayed out when the Automatic Document
Feeder is selected under Document Source.
The preview feature is disabled when the Automatic Document
Feeder is selected because the document would have to be fed
through the feeder for the preview scan and then reinserted
into the feeder for the final scan. If necessary, use the document
table for previewing your document.
6-4 Troubleshooting
Auto
Locate does not work when scanning two or more originals.
Make sure none of the documents are touching one another on
the document table.
When you scan a monochrome image, the scanned image is
reversed like a negative image.
If your application has an invert function, use it to reverse the
image, or use the Invert option on the TWAIN advanced screen.
Some applications misinterpret the
scanner
data. Check with
the application’s manufacturer for an updated program version.
The default settings for Image Type and Destination don’t meet
your specific scanning requirements.
You can define your own settings; see Chapter 3.
The Halftone setting in the Image Type dialog box is grayed out.
Halftone and dither settings on most EPSON scanners are only
available when the Pixel Depth setting is set to Black & White
or 8
Colors
(1 or 2 bits per pixel per color).
The application software displays an error message, freezes, or
fails after scanning.
Make sure you close the TWAIN screen before switching to
your application software.
The image you scanned may be oversized. Try reducing its file
size by changing its resolution or dimension; then scan it again.
If you selected 16 Gray as the Pixel Depth setting, change to
256 Gray and try scanning again.
Troubleshooting 6-5
If you scanned an image at a high resolution (800 dpi) and at
the maximum allowable width using the Color Photo Image
Type setting, restart your Macintosh and reduce the resolution
and the width of the scanned image. Then try scanning again.
If your application contains a scan manager feature, you may
have closed it before closing the EPSON TWAIN screen. Scan
your image again, but close the
your application’s scan manager.
If you selected 3-pass scanning in EPSON TWAIN, you may
need to free some space on your hard disk to scan.
After scanning with an image editing application, the scanned
image disappears.
Make sure you close the TWAIN screen before switching to
your application software.
The rows in the screen calibration window do not match closely
enough.
Try adjusting your monitor’s brightness and contrast settings.

After closing the EPSON TWAIN screen, a partial image of the
screen appears over the scanned image.
Scroll the application’s frame to clear the partial image.
After selecting a part of an image to scan, the image did not scan
correctly.
Scan the whole image instead of a portion of it.
Problems With Image Quality
This section tells you how to fix problems with image quality
that may occur when you scan or print images.
The entire image is distorted or blurred.
Make sure that the document is placed flat against the
document table.
You may have moved the document during scanning. Check
the position of the document.
See that the scanner is not tilted or placed on an unstable
surface.
Troubleshooting 6-7
Part of the image is distorted or blurred.
Part of the original may be wrinkled, warped, or not in contact
with the document table. Be sure the document is uniformly
flat.
Caution:
Do not place heavy objects on the document table.
The edges of the document are not scanned.
The document table has non-readable areas around the edges.
Adjust your document’s position so that the image comes
inside the readable area.
Color is patchy or distorted at the edges of the document.
If the original is very thick or warped at the edges, the edges of
the image may be discolored. Cover the edges of the original
with opaque paper to avoid having outside fight interfere.
If part of the original is outside the document table, the edge
may not be in contact with the document table and may be
discolored. Change the position of the original.
The image is faint or out of focus.
Make sure the document is placed flat on the document table.
Check your Gamma Correction setting.
Make the
Brightness setting

Make sure you have performed the calibration procedures and
selected the correct printer profile; see Chapter 2.
Try different combinations of scanner settings.
Check that your software is correctly installed.
If you are importing an image file into your application
software, see if the file format is acceptable for your software.
Also check that the settings of your application and your image
match. See your application software manual.
A line of dots is always missing on the scanned image.
If this happens only on your printed image, your printer or its
print head may have a problem or need cleaning; see your
printer manual.
If this happens on both your screen and printout, the scanner’s
sensor may be malfunctioning. Consult your dealer.
Troubleshooting 6-9
Using halftoning, textured dot patterns appear in the image.
This is normal halftoning; see your scanner manual for
examples.
The color on the video display seems different from that of the
original image.
Depending on your monitor, its resolution/color settings, and
your EPSON TWAIN settings, the screen colors may be
different from the original. This may be normal, especially if
colors in the printed image more closely match the original.
Make sure you have correctly performed the screen calibration

The colors in a printed image may not match the colors of the
original image exactly because the scanning and printing
processes use two
different
color interpreting technologies.
The printed image is larger or smaller than the original size.
Check the image size settings in your application and TWAIN.
You may also have used the Zoom Preview icon. Do not use
the size of the image on your monitor to judge the printed size.
6-10 Troubleshooting

on your
scanner, some features may not be available.
Set the Brightness, Highlight, or Gamma Correction options
to darker settings and scan the image again.
If you selected Line Art as the Image Type setting and any
setting other than Screen as your Destination setting, try
increasing the Threshold setting to a higher value.
Moiré (interference) patterns appear in the scanned image.
Moiré patterns commonly occur when you scan images that
include halftone screens. To
