Features
The EPSON Perfection 2450 Photo scanner offers the following
features:
❏Optical resolution of 2400 dots per inch (dpi) for main
scanning, and 4800 dpi with micro step for sub scanning
(16-bit input, 16-bit output).
❏The EPSON Perfection 2450 Photo has the Film Adapter
(hereafter, the Film Adapter is called the “integrated TPU”),
which enables slides and film to be scanned. The integrated
TPU has also the same function as the document cover.
❏Start Button control for one-step scanning.
The
]Start button can automatically start a scanning
sequence by invoking EPSON Smart Panel and EPSON
TWAIN, scanning the document, launching an application,
and importing the scanned image to the application.
❏Full color or grayscale scanning. Capture your images with
up to 281,500 billion colors, or up to 65,536 shades of gray.
❏EPSON TWAIN lets you take full advantage of your scanner's
advanced features.
❏EPSON TWAIN’s Unsharp Mask option automatically
sharpens the image to provide crisp detail.
❏EPSON TWAIN’s De-screening option automatically
removes unwanted moiré patterns from scanned images for
higher quality output.
❏Auto Area Segmentation (AAS) allows you to separate text
from photographs on a page so that grayscale images are
clearer and text recognition is more accurate.

2-2 Scanning Basics
Scanning Procedure
For reflective documents
You need to perform the following procedure to scan the
reflective documents on your scanner using a TWAIN-compliant
application. Details are described below.
1. Place a document on the scanner.
2. Start a TWAIN-compliant application.
3. In the application, open EPSON TWAIN 5 using a command
such as Acquire.
4. EPSON TWAIN automatically previews the images, and
recognizes the document source and type. Images are
automatically optimized and scanned.
5. Save the scanned images.
This following sections describe each of these steps in details.
For transparent materials
This scanner is suitable for scanning of slides and film. You need
to perform the following procedure to scan the transparent
materials using the integrated TPU. Details are described below.
1. Remove the reflective document mat from the integrated
TPU.
2. Load slides or film into the film holder and set it with the
integrated TPU.
3. Start a TWAIN-compliant application.

Scanning Basics 2-3
4. In the application, open EPSON TWAIN 5 using a command
such as Acquire.
5. EPSON TWAIN automatically previews the images, and
recognizes the document source and type. Images are
automatically optimized and scanned.
6. Save the scanned images.
Note:
For more details, see your Online Reference Guide.
Placing a Document on the Scanner
1. Open the integrated TPU.
Note:
Do not place heavy objects on the glass of the document table. Also,
do not press the glass of the document table with too much force.

2-4 Scanning Basics
2. If the reflective document mat is not attached, you need to
attach it. Hold the top of the document mat and slide it down
gently along the integrated TPU.
Note:
When scanning reflective documents, make sure the reflective
document mat is attached. Otherwise images cannot be scanned as
expected.
3. Adjust both bottom corners of the reflective document mat to
the position fittings of the integrated TPU and then insert the
reflective document mat in the top and bottom position
fittings of the integrated TPU.

2
Scanning Basics 2-5
4. Place the document on the document table, with the side to
be scanned facing down. Make sure that the document is
carefully aligned with in the corner of the document table as
shown below.
Note:
The area with a width of maximum 2.1 mm from the horizontal guide
and 1.5 mm from the vertical guide is not scanned.
2.1 mm (max.)
1.5 mm (max.)

2-6 Scanning Basics
5. Close the integrated TPU gently so that the document does
not move.
Note:
❏Do not leave photographs on the document table for an extended
period of time as they may stick to the glass.
❏Make sure the document is flat against the glass surface,
otherwise the image will appear fuzzy and out of focus. Also be
sure to close the document cover to prevent interference from
external light.
❏Always keep the document table clean. See “Maintenance” in
your Online Reference Guide.
Now you are ready to scan. Follow the instructions described in
the rest of this chapter, or see your Online Reference Guide for more
details on using your scanner.
Scanning an Image
Before scanning a document, remember to respect the rights of
copyright owners. Do not scan published text or images without
first checking the copyright status.
There are two ways to scan: using the
]Start button (see your
Online Reference Guide), or using a TWAIN-compliant application
(see the following section).
Note:
❏You cannot scan an image which exceeds the available memory or
disk space. If you try to scan a very large image, an alert appears on
the screen.
❏After an image is scanned, be sure to save it.

Scanning Basics 2-7
1. Make sure that the scanner is connected to your computer and
turned on. Also check that the Indicator light stays on (green),
and the image is set to the scanner.
Note:
❏A flashing indicator light (red) indicates an error; in this case
see “Troubleshooting” in your Online Reference Guide to
troubleshoot the problem.
❏The fluorescent lamp turns off if no command arrives from the
computer within 15 minutes. This is normal and the lamp turns
back on once you start scanning.
2. Start a TWAIN-compliant application. (The example used
here is Adobe®Photoshop®Elements.)
3. Select Import from the File menu, and then select EPSON
TWAIN 5.
Note:
Depending on your application, you need to choose EPSON
TWAIN 5 only the first time you use the scanner with the
application.
EPSON TWAIN automatically previews the image and
recognizes the document type.

2-8 Scanning Basics
Note:
When the scanner is warming up, you cannot click Cancel.
Note for Macintosh users:
Most illustrations shown in this chapter are for Windows, so they
may be different from the actual dialog boxes that appear on your
screen. However, you can use the dialog boxes for both Macintosh
and Windows reference, as almost all the settings and functions are
the same.
4. After EPSON TWAIN has previewed and recognized the
document type, the following dialog box appears with a
progress bar to indicate the scanning progress. You can see
the document type and the icon. When scanning multiple
photos, you can also see the number of scanned images.
Images are automatically optimized. You can scan easily and
quickly without changing any complex settings. EPSON
TWAIN automatically recognizes the image type, locates the
target image, detects the skew of the target image, adjusts the
exposure, and then starts scanning.
Note:
Depending on your application, you may not be able to scan multiple
images.
