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.

EPSON Stylus COLOR IIs For these printers you simply select the printer calibration
profile before you scan an image. See “Scanning Using Calibration” on page 2-8.
If you have a color printer that is not an EPSON Stylus, you must create a printer calibration profile using the instructions in this section.
To create a printer calibration profile, you must perform these operations:

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.

150-350
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:
General Screen Impact dot printer
Laser Printer 600 Stylus COLOR Stylus COLOR II
Thermal Printer Stylus COLOR Ils

Utilities, you can create your own calibration profiles for any color
printer you use. For more information, see Chapter 2.

After starting a multipage scan using the Automatic Document
Feeder, the image editing application freezes, displays an error
message, or fails.
Reset the system and reduce the number of pages you are scanning with the Automatic Document Feeder.
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
darker.
Make sure you have calibrated your monitor and printer to your scanner, and that you are using the resulting calibration profile. See Chapter 2 for more information
6-8 Troubleshooting
The image is too dark and without details.
Adjust the settings to lighter values and scan
Brightness, Gamma Correction,
the
image again. Also check
and
Shadow
the brightness and contrast values of your monitor.
Check that the Destination output device is set correctly. If it is set to
Screen,
output on a printer may be too dark.
Straight lines in the image are jagged.
The document may be placed at an angle on the document table. Align it so that the horizontal and vertical lines are carefully aligned with the rulers on the document table.
The image does not look the same as the original.
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 process in EPSON Scan! II. Recalibrate and try again.
Check
Correction,
your
scanner settings-such as
and
Color Adjustment-or try a different

combination of settings.
The printed color seems different from that of the originals.
Check that you have correctly performed the printer calibration process in EPSON Scan! II using the correct printer calibration profile. Recalibrate and try
again.
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
The image cannot be printed on the printer, the printout
is
garbled, or the printout is not an image.
Check that the printer is properly connected to your Macintosh and is set up correctly; see your printer manual.
Check that your software is properly installed and set up for
your printer; see your software manual.
Images
cannot be scanned
at all or only a few dots appear in the
scanned image.
Try different EPSON TWAIN settings. Be aware that some
settings disable others for a particular effect. Also, depending
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
minimize this effect, try any of the
following solutions:
Move or angle the original slightly Change the Sharpness setting Change the Scale setting slightly
Select 3 pass
for the Scanning Sequence.
Troubleshooting 6-11
When you
select 16 Gray for the Pixel Depth setting, the scanned
image appears black in your application software.
Choose 256 Gray for the Pixel Depth setting and try scanning
again.
The image appears upside down and truncated in your application
software after scanning.
Before you scan the image, reduce its file size to less than 1MB
by adjusting settings on the TWAIN advanced screen.
When you select
256
Color for the Pixel Depth setting, the scanned
image does not match the previewed image.
Select Color Photo as the Image

The image looks corrupted.
Check your printer driver settings. If the paper size is set larger
than Letter or A4, select a smaller paper size or the maximum paper size your scanner can support. See your scanner documentation for more information.
You may need to choose a lower resolution for the video
display setting
using the Monitor
Control Panel. See your
