Connecting to the Host Computer
This scanner connects to a host personal computer through a SCSI interface. This section
provides an overview of SCSI, and explains
how to connect the scanner to a host computer.
What is SCSI?
“SCSI” (Small Computer System Interface)
is an interface standard that is used for highspeed data transfer between a peripheral device
and a host computer .
• In a SCSI connection, ANSI-compliant
SCSI cables are used to connect one or
more peripheral devices in daisy chain
fashion to the host computer .
• Each device is assigned a unique SCSI
ID (0 to 7), which must be set for the
device before turning on the power and
before turning on the computer.
• The last device in the daisy chain requires
a terminator.
1: SCSI cables
2: Up to 7 devices
3: T erminator
Important
❒ If two or more devices in a daisy chain
share the same SCSI ID, misoperation
and data loss may result. Set a unique
SCSI ID for this scanner that does not
duplicate the SCSI ID of any other device.
SCSI Connection Requirements for the Scanner
• This scanner complies with the SCSI-2
standard. SCSI-1-compliant peripheral
devices can also be connected and used
with this scanner. The SCSI interface on
the scanner has a 50-pin half-pitch (pin
type) connector. Connect an ANSIcompliant shielded SCSI-2 cable to the
scanner . Note that some combinations of
cables and SCSI boards will not work
together properly , so check this carefully.
• If you are using a SCSI board and driver
software that supports SCAM, the SCSI
ID of this scanner will be set automatically , so there is no need to set the ID. If
you are using a driver that does not have
a SCAM function, it will be necessary to
set the SCSI ID for the scanner if the
SCSI ID is identical to that of another
device that is connected.
• The scanner’s ter minator can be enabled
or disabled by turning a DIP switch on or
off.
Page 25
11
Important
❒ The total length of the SCSI cables, in-
cluding the length of the cable inside
the personal computer, should be no
more than 3m (9.8 ft.) when using Fast
SCSI, and no more than 6m (19.7 ft.)
when using non-Fast SCSI.
❒ Some combinations of SCSI boards and
peripheral devices that are connected
simultaneously may not work together
properly.
Setting the SCSI ID
A
Turn the rotary switch to set the SCSI
ID number.
Note
❒ If you change the setting while the
power is on, it is necessary to initialize
the scanner. Refer to P.16, “Initializing the Scanner.”

❖ Originals that cannot be set in the Auto Document Feeder (ADF)
Setting an original that falls in one of the following cate gories in the Auto Document Feeder
(ADF) could result in a paper jam or in damage to the original. Such originals should be
placed on the contact glass.
• An original that does not fall within the “Recommended Sizes and Weights of Origi-
nals”
• An original that includes staples, paper clips, glue, or other adhesives
• An original that has holes or is torn
• An original that is warped, creased, or wrinkled
• An original that is pasted together
• An original that has some sort of surface treatment, including thermal paper, art board,
silver paper, carbon paper , or conducti ve paper .
• An original that has index tabs, stick-on notes, or other protrusions
• An original on paper that does not slide easily, such as tracing paper

Difficult to Detect Sizes
When the optional Image Processing Unit T ype A is installed, the scanner can automatically detect
the size of an original. However, the sizes of the following types of originals are difficult to detect
properly, even if using a scanner driver that supports automatic detection of the size of the
original:
• An original that has index tabs, stick-on notes, or other protrusions
• An original that is highly transparent, such as transparencies or tracing paper
• Documents on a dark background
• Documents with text, illustrations, or filled in portions on the leading edge
• An original that is not A3K, B4K, A4K, B5K, A5K, B6K, A6K, DLTK, LTK, or

DIP Switches
Only the settings of DIP switches 1 through 3 can be changed. Do not change the settings of the
other switches.
Important
❒ If multiple scanners with the SCAM function enabled are connected on the same daisy
chain, the host will not be able to recognize the IDs. In this case, set DIP switch 1 to
“ON”(SCAM function disabled), and set the SCSI ID with the rotary switch.
❒ If the daisy chain is too long, or if a nonstandard SCSI cable is used, misoperation may
occur during synchronous transfer. In this case, set DIP switch 2 to “ON” (SCSI
synchronous transfer disabled).
❒ If this scanner is connected in the middle of a daisy chain, set DIP switch 3 to “ON”
(internal SCSI terminator off).
Leave these set to “OFF;” do not
change.

Preview
This function scans the entire scanning area at low resolution (100dpi*). The preview image can
then be viewed while setting the scanning area for the final scan. The preview function can also
be used to get a quick view of the scannable area.
* “dpi” is an abbre viation for “dots per inch,” and indicates resolution. A larger value indicates
greater detail.
Page 59
45
Functions
Scan
This function scans an original once the scanning area, scanning composition, resolution, and
other values have been set.
When setting these values, consideration should be given to the original that is to be scanned and
to the output device (display , printer , etc.). For example, it is meaningless to scan an original at
high resolution if the resolution of the output device is lower than the scanning resolution,
especially because high-resolution scanning uses a great deal of memory and requires more
processing time.
Scanning Composition
There are three scanning composition modes: binary scanning, halftone scanning, and multivalue scanning.
❖❖
❖❖
❖ Binary scanning
This mode scans the original in black and white. This mode is used to scan originals that
consist only of text, line drawings, and other elements that lack intermediate colors.
❖❖
❖❖
❖ Halftone scanning
This mode scans the original in pseudo-halftones created by dots. This mode is used to
output an original that contains intermediate colors, such as a photo, on an output device that
can only express binary per pixel, such as a laser printer .
❖❖
❖❖
❖ Gray Scale scanning
This mode scans the original with 16 or 256 gradations. This mode is used to output an
original that contains intermediate colors on an output device that can express different
gradations for a single pixel, such as a Dye Sublimation printer or a display .
Original Binary
Halftone Gray Scale
Page 60
6. Appendices
46
Binary Scanning/Threshold
The binary scanning function converts the original into black and white image data. If the original
contains any intermediate colors, they are compared with the threshold value and determined to be
either black or white accordingly . The threshold value can be set to an y of 255 gradations; any
intermediate colors that are brighter than the threshold value are scanned as “white, ” and those that
are darker than the threshold value are scanned as “black.” This mode should be used to scan
originals that have no intermediate colors and consist of only two colors, such as text or line
drawings.
The threshold value should be set according to the intensity of the original. For example, setting
a high threshold value when scanning faint text will produce te xt that is much clearer. Con versely ,
setting a low threshold value when scanning an original that is on a colored background (such as
text on colored paper) will eliminate the background color from the scan.
There are two modes for the threshold value setting:
Limitation
❒ During double-sided scanning, this function is valid only for the front side of the original.
❖❖
❖❖
❖ Standard mode
Any one of 255 values can be set.
❖❖
❖❖
❖ Dynamic threshold mode
This function is valid only when the optional Image Processing Unit Type A is installed.
With this mode, the optimal threshold value (given the brightness of the original) is set
automatically.

Halftone Scanning
Halftone scanning converts the original into an image consisting of pseudo-halftones produced
by dot shading (in which shading is achieved through combinations of black and white dots, as
in newspaper photographs). This function is used to output an original that has intermediate
tones, such as a photo, on an output device that can only produce monochrome output, such as a
laser printer.
Because halftone scanning expresses pseudo-halftones, it does not require as much memory,
making it effective for filing a large volume of images. There are eleven types of halftones (ten
dot shading patterns and one error diffusion pattern) for selection. It is also possible to scan and
download your own dot shading patterns.
The names in parentheses indicate the names under the ISIS driver .

Gray Scale Scanning
Glay Scale scanning converts an original into image data consisting of 4-bit or 8-bit gradations.
Four bits can express 16 gradations, and eight bits can express 256 gradations. This function is
used to output an original that contains intermediate tones on an output device that can express
intermediate tones for a single pixel, such as a display or a Dye Sublimation printer .
Although a higher number of bits produces higher image quality , it is important to remember that
the processing time will be longer. F or example, when an area is scanned using the 8-bit multiscan mode, it requires eight times as much memory as when scanning the same area through
binary scanning or halftone scanning.
Limitation
❒ When this function is used during duplex scanning, there are limits on the front and image
data size: 3.6 million bytes with gray scale scanning, and 4 million bytes with binary
scanning
❒ During double-sided scanning, this function is valid only for the front side of the original.
data size for the reverse side is 360 million bytes.
Note
❒ When using this function, the image on the reverse side might be scanned through the
document, depending on the condition of the original.

Area Extraction
This function extracts and scans a specified rectangular area within a scanning area.
For example, to scan just the photograph portion of the original shown belo w, specify the area
where the photograph is located. The rectangular area is specified by specifying the coordinates
of the upper left corner of the rectangle, and the vertical and horizontal lengths.

Section Area (Multi-area Settings)
This function permits the specification of up to four rectangular areas of any size within the
scanning area, each of which can be set as the scanning area. When overlapping areas are set, the
area that was set last takes priority .
For example, when a single original contains both text and photos, specify rectangular areas for
each, and then set binary scanning mode for the text areas and halftone scanning mode for the
photographs. This function allows each area to be scanned in its respective scanning mode in one
scan.
Limitation
❒ During double-sided scanning, this function is valid only for the front side of the original.
Note
❒ Note that scanning might not be performed in the specified manner if any of the four
rectangular areas overlap. In this case, either decrease the number of rectangles, or
else reduce them in size.
❒ This function is valid only when the optional Ima ge Processing Unit Type A is installed.

Functions
Auto Photo/Letter
This function automatically determines whether the image being scanned is text (binary image) or
photo (intermediate tone image), and scans the text areas in binary scanning mode and the photos
in halftone scanning mode. This function is used in order to automatically scan text in binary
scanning mode and photos in halftone scanning mode. This function allows you to scan an
original that contains both text and photos just once while automatically scanning each type of
area in the appropriate scanning mode without having to make special settings for each.
Limitation
❒ During double-sided scanning, this function is valid only for the front side of the original.
Note
❒ This function is valid only when the optional Ima ge Processing Unit Type A is installed.

Resolution
This function permits setting separate resolutions for the main-scanning and the sub-scanning,
over a range of 100dpi to 800dpi (in 1dpi increments) for each. A high resolution setting requires
more free space in memory and requires more processing time.
Basically , when outputting a scanned image that is the same size as the original image, set the
same resolution as that of the output device. Image quality will suffer if the resolution is less than
that of the output device, and it is meaningless to set a resolution that is higher than the resolution
that the output device is capable of. However, if the output image is to be enlarged or reduced
compared to the original, change the resolution by the same ratio.

Low resolution High resolution

Brightness
The brightness can be adjusted to 255 levels. If a high value is set for the brightness, the image
will become brighter overall. If a low value is set, the image will become darker overall.
When scanning a dark original, set a high value for the brightness; when scanning a bright
original, set a low value for the brightness. For e xample, if a dark original is scanned normally ,
any gradations in the darker portions will be lost and will appear to be solid black in the scanned
image. By increasing the brightness value in this case, the gradations in the darker portion will
also appear in the scanned image. Conv ersely , if the bright portions of an original become solid
white in the scanned image, lowering the brightness value will bring out the gradations in the
bright portion in the scanned image.
Contrast
The contrast can be adjusted to 255 levels. If a high contrast value is set, the resulting image will
have high contrast and will be sharply defined. If a low contrast value is set, the resulting lowcontrast image will have a softer feel.
To produce a sharp ima ge, increase the contrast value, to produce a soft image, decrease the
contrast value. For example, when scanning a photo of metal, glass, etc., set a high contrast value
in order to achieve a sharp feel.

Document Size Detection in the Auto Document Feeder (ADF)
5mm (0.2")
Note
❒ If there is any coloring on the leading edge (5mm, 0.2”) of the original, the size of the
original might not be detected properly.
❒ If the sheets of the original are not set in position properly, the size of the original
might not be detected properly. Line up the edges of the sheets of the original, and
position the guides on both sides so that they are touching the edges of the original and
will ensure that the original feeds straight into the ADF.
❒ This function is valid only when the optional Ima ge Processing Unit Type A is installed.

Functions
Erase Background
This function permits selection of the white side dynamic range for scanning.
When Erase Background is disabled
The dynamic range is set so that a white original (D value: 0.07) reaches maximum output.
When Erase Background is enabled
During scanning, the portion of the original that is closest to white is deemed to be white, and
the dynamic range is set so that the portion in question reaches maximum output.
