About this Document
This document is part of the set of user manuals provided with the AFHCAN Cart. These user
manuals, covering various topics, are normally assembled into a binder delivered with each Cart.
This modular design has the following advantages:
• the set of manuals provided with your cart includes documents for the specific peripheral
devices installed
• each document is a stand-alone publication; as new devices or features are added to the
Cart, new manuals can be added to the existing binder
• user information that is common to all items of equipment does not need to be repeated in
each module, but can be covered in separate modules and referenced as needed
Related Documents
This document assumes you have read the introductory hardware and software manuals included
in this binder.
The original manuals provided with the equipment were included in a set of materials delivered
with the AFHCAN Cart. Those manuals can be used to supplement the information provided in
this document. Be aware, however, that items installed on an AFHCAN Cart may have been
modified slightly, so the features as described in the original product manuals may not apply.
For More Information
This document describes the equipment to a level of detail that will meet most user's needs in the
context of clinical use of the AFHCAN Cart. For more information, contact AFHCAN Customer

Section 1 – Introduction
1.1 Introduction to the Scanner
This manual describes the features and operation of the scanner as installed on an AFHCAN Cart.
Four scanner models are covered (see Figure 1):
• Epson Perfection Model 1640
• Epson Perfection Model 1650
• Epson Perfection Model 4490
• Epson Perfection Model 4990
Figure 1
Four scanner models
Models 1640 and 1650 were part of the original deployment of AFHCAN Carts. These models
work well in the AFHCAN installation, but are no longer being manufactured. Model 4490 is
standard for new installations, or may be selected as a replacement for the previous models.
Model 4990 is an option that can be ordered in place of the 4490, and allows for 8-inch by
10-inch transparencies such as x-rays to be scanned.1
In general, the AFHCAN software functions the same for all the scanners that have been
deployed with the AFHCAN Cart. There is no significant difference in the basic operating
sequences. However, with the newer scanners, the appearance of certain screens may vary
slightly from the illustrations shown in this manual.
1
Scanning of transparencies requires the use of manual mode, which is an advanced scanning feature.
Information on manual mode will be provided separately. Consult the Epson documentation for details.

The scanners have a variety of buttons on their front panels. None of these buttons interact with
the AFHCAN software, so they are not described here. Model 1650 does not have a power
switch, but the other three models do. As installed on the AFHCAN Cart, the scanner power
switch is not readily accessible. It is the standard practice on the AFHCAN installation to leave
the scanner power button on at all times and to control power to the scanner via the Cart’s main
power switch. This power distribution strategy applies to most other devices on the Cart. For
exceptions, refer to device-specific modules in this binder for details.
1.1.1 Functional Description
The scanner is used to scan paper documents, photographs, or other items into a case. The
AFHCAN software activates a TWAIN driver, which is software that comes with the scanner.2
The TWAIN driver controls the operation of the scanner.
The AFHCAN software and the TWAIN driver interact differently depending on which scan
mode is selected. The AFHCAN software offers two scan modes:
• black and white (Scan button)
• color (Scan Color button)
In black and white mode (Scan mode), the AFHCAN software directs the TWAIN driver to scan
in black and white. Each pixel is forced to be either white or black (in other words, shades of
gray are lost). This is useful when scanning black and white forms or other documents where
high contrast is a plus. The downside is that if there are items which are lightly shaded, those
items may be dropped, and the overall image resolution may appear to be diminished. In Scan
mode, a small window appears indicating that a scan is underway. Scan mode saves files in a
PNG image format.
In the Scan Color mode, the TWAIN software performs the following steps:
• previews the image to determine the type of image, image area, and image characteristics
• automatically adjusts the image resolution, size, and other attributes
• scans the image and saves it in a JPG image file format
• sends the image file to the AFHCAN software for inclusion in a case
When running on a Cart, the software resets the TWAIN driver to factory defaults each time the
AFHCAN software is started. This places the TWAIN driver in automatic mode.
Note: When the software is running on a PC workstation, the reset
does not take place, which means the TWAIN driver will open in the
same mode and with the same settings that were in effect when the
software was last used.
In automatic mode, the preview is analyzed to determine the type of image, the image area, and
any optimal settings. The TWAIN software distinguishes the types of images listed in Table 1.
2
The term TWAIN refers to software that fits between the user application and a device (scanner, camera,
etc.) TWAIN drivers make it easier to standardize the integration and control of various devices on a
computer system. For more information on TWAIN, go to www.twain.org.

Note 1: The exact criteria by which automatic mode categorizes items is difficult to determine. The descriptions shown
here are based on tests with the Model 1650 scanner. In some cases, the image preview assigned an image type other
than what was expected. However, we found that automatic mode always produced reasonably good scans.
During the preview, it is possible to interrupt the automatic scan and activate the TWAIN driver's
manual mode. Manual mode allows the user to manually control a number of image attributes
such as resolution, color balance, and image area. The use of manual mode is not recommended
for most AFHCAN installations.
Note: The settings in manual mode are complex and are beyond the
scope of this manual (refer to the Epson documentation for details).
For those not familiar with advanced scanning features, manual mode
can cause a lot of confusion, and can lead to technical difficulties or
poor quality scans. Furthermore, some combinations of manual
settings can generate huge files and may lead to system freeze-up.
Please be aware that the last scanner mode used becomes the default
mode for the next session. If someone goes into manual mode and
does not set it back to automatic mode, the next person to use the
scanner will encounter the screen for manual mode. Software running
on an AFHCAN Cart will reset the TWAIN driver to automatic mode
each time the software is restarted.
On completion of the scan, the TWAIN driver saves the file and notifies the AFHCAN software
that a scanned file has been saved. If for some reason the TWAIN driver cannot complete the
scan, the AFHCAN software will display a Scan Failed message.
There are several situations that can cause a Scan Failed message to appear in the AFHCAN
software. Some of the more obvious ones are the following:
• the scan was canceled in the TWAIN driver window
• scanner power switch is turned off or the scanner power cable is disconnected
• scanner data cable is disconnected
PUB-119 Rev B.doc
3
User's Manual
Scanner
Epson Perfection
• the incorrect TWAIN driver has been selected
Each scanner model requires a specific TWAIN driver. If the TWAIN driver does not match the
scanner model, the AFHCAN software will bring up the Scan Failed message when you attempt
to scan.
The correct TWAIN driver is normally installed and tested when the scanner is installed.
Normally it should not need to be changed. However, if the Scan Failed message appears, you
will be invited to open a pop up window allowing you to select a different TWAIN driver.
Note: Selecting a new TWAIN driver typically would apply only
when a different model scanner is being installed.
Table 2 lists the scanner models and associated TWAIN drivers. (Other TWAIN driver options
may appear in the window that may not apply to scanners. Disregard any drivers not listed in
Table 2.)

1.1.3 Scanner Features in the AFHCAN Software
1.1.3.1 Primary Features
The AFHCAN software provides a means for activating the TWAIN driver and for handling the
image that the TWAIN driver returns. To scan an image, press the Scanner button on the Add
To Case screen. Figure 12 shows the initial Scanner screen. Table 7 shows the buttons on the
Scanner screen and describes their functions.
Figure 12
Initial appearance of the Scanner screen
Table 7
Functions of Scanner screen buttons
Button
Function
Pressing the Scan button activates the TWAIN driver and initiates a scan.
The Scan button is used for scanning documents where a high-contrast,
black-and-white image is desired. When the Scan button is used to initiate a
scan, the software forces each pixel in the image to either 100% black or
100% white. This enhances the contrast for documents like forms, but
removes shading information needed for photographic images. The resulting
image file will be somewhat compressed, meaning it requires less memory and
takes less time to send and receive. The Scan button can be pressed
repeatedly to scan additional items. Each scan will be stored as a thumbnail
on the Scanner page.
PUB-119 Rev B.doc
12
User's Manual
Scanner
Button
Epson Perfection
Function
The Scan Color button is similar to the Scan button in that it activates the
TWAIN driver and initiates a scan. Scan Color tells the AFHCAN software to
receive and store the image exactly as provided by the scanner. In automatic
mode, the scanner will determine the type of image and the appropriate image
settings. Color and shading information will be retained making Scan Color
more suitable for photographs. Scan Color may provide better results on
some forms having higher levels of detail. The Scan Color button can be
pressed repeatedly to scan additional images. Each scan will be stored as a
thumbnail on the Scanner page.
The Rotate button rotates the scanned image 90%. Rotate can be pressed
any number of times to bring the image into the desired orientation. This is
useful for getting text right-side-up when originals are in landscape mode.
Image rotation must be done before the image is saved to the case.
The Save button saves one or more scanned images (thumbnails) into the
case and returns to the Case screen. It is always possible to add more scans
by going to the Add To Case screen and pressing the Scanner button.
The Back button exits from the Scanner screen and returns to the Add To
Case screen. If any scans have been obtained, a warning message will
appear. If the action is confirmed, the images will be erased.
Once a scan has been initiated, the TWAIN driver displays a pop-up window over the Scanner
page, as shown in Figure 13. Windows for Models 4490 and 4990 have a different appearance,
but offer the same functionality.
Figure 13

User's Manual
Scanner
Epson Perfection
The preview function does a quick scan of the original to determine its type and area (image types
are listed in Table 1). When actual scanning begins, the TWAIN pop-up has the appearance
shown in Figure 14. Figure 15 shows the Scanner screen after scans have been obtained.

Epson Perfection
When the scan is completed, a thumbnail of the scan will be added in the left column, and the
scanned image will be displayed in the middle area of the screen (Figure 14). All images must be
given a name. The AFHCAN software will automatically enter the word SCAN with a sequence
number. You can type in a different name manually. At this point, the selected scans can be
saved to the case by pressing the Save button. To discard all the currently displayed scans, press
Back.
1.1.3.2 Recovering from Manual Mode
As mentioned previously, manual mode is complex and is not recommended for routine scanning.
Details on manual mode are beyond the scope of this manual. However, if another user scans
with manual mode, you may encounter the TWAIN screens for manual mode when you do a new
scan. This is because the software remembers what mode was used last and opens the next
scanning session in the same mode. Clicking Cancel during preview brings up the screen show
in Figure 16. Clicking Manual Mode in Figure 16 brings up the screen in Figure 17.

Pressing the Full Auto mode button returns to the screen in Figure 16. Pressing Scan in Figure
16 returns to the screen in Figure 13.
1.1.3.3 Scan Failure
If for any reason the TWAIN driver cannot complete the scan, it will notify the AFHCAN
software. The AFHCAN software will display the message shown in Figure 18.
Figure 18
Scan failed message
PUB-119 Rev B.doc
16
User's Manual
Scanner
Epson Perfection
The TWAIN drivers for various scanners were listed in Table 2. Possible causes of Scan Failed
error message include but are not limited to the following:
• not placing an original on the document table
• manually cancelling a scan (while not the preferred method, it is possible to cancel a scan
during the preview: on the screen shown in Figure 12, push Cancel, then on the screen
shown in Figure 15, push Close)
• scanner power turned off (difficult to do on the V3 Cart)
• a scanner cable has been disconnected (cables are well protected on the V3 Cart)
• an actual malfunction of the scanner (the indicator light will flash red)
• the TWAIN driver does not match the scanner model (the TWAIN driver is selected and
tested by qualified personnel when the scanner is installed)
Users may be able to clear this message as follows:
1. click the Yes button to view the list of drivers
2. click OK to accept the highlighted driver (the correct driver should be established when the
system is installed and should not need to be changed)
3. click the Scan or Scan Color button
If the problem persists, contact AFHCAN Customer Support at 888-449-4435.
1.2 Particulars of the AFHCAN Installation
On the V3 Cart the scanner is in the second drawer (Figure 19). This limits access to the power
switch, the cables, and the scanner transport locks. The scanner power switch is normally left on
with power to the scanner being controlled via the Cart's main power switch.
The use of equipment options such as a sheet feeder or separate transparency unit are not
supported in the AFHCAN installation.
The front panel buttons on the scanners do not interact with the AFHCAN software.
The position of the scanner in the drawer does not permit the scanner cover to be opened to the
full 90 degree position. As installed in the second drawer on the V3 Cart, the Model 4490 cover
opens to the first detent (about 45 degrees). Scanner covers should not be removed.
