Options In this section, we refer to the options for this machine. Options Image Processing Unit Type B Installation of this option enables the following visual image processing by use of the TWAIN driver. ❖ Binary(Auto Image) When you binary-scan an original mainly with text files, this machine automatically detects and scans an appropriate threshold value. ❖ Binary(Text/Photo) Set when you scan an original consisting of both texts and photos. It scans with binary, and automatically detects and scans the photos to represent a para-intermediate tone (gray) with a black and white net-dot pattern. ❖ Select Range 6 Set when you Binary-scan an original consisting of both texts and photos. You can set the photo part alone as the para-intermediate (gray) tone. For an orig- inal mainly occupied by photos, to the contrary, you can detect and scan the original as a whole as the para-intermediate (gray) tone, setting the text part alone as non-intermediate (gray) tone. The maximum number of ranges to have partially different setting from the overall setting is 4. IEEE1394 Interface Unit Type IS760 You can connect your PC to the IEEE1394 Interface board Two IEEE1394 connectors are available, and you can connect a total of 3 PCs to this machine together with another SCSI connector equipped. Limitation ❒ The pre-installed USB 2.0 interface board is to be used exclusively. Note ❒ You cannot use simultaneously two or more PCs connected. Connection is automatically switched to either SCSI, IEEE1349-1 or IEEE1349-2. 85

Options
In this section, we refer to the options for this machine.
Image Processing Unit Type B
Installation of this option enables the following visual image processing by use
of the TWAIN driver.
❖
Binary(Auto Image)
When you binary-scan an original mainly with text files, this machine auto-
matically detects and scans an appropriate threshold value.
❖
Binary(Text/Photo)
Set when you scan an original consisting of both texts and photos. It scans
with binary, and automatically detects and scans the photos to represent a
para-intermediate tone (gray) with a black and white net-dot pattern.
❖
Select Range
Set when you Binary-scan an original consisting of both texts and photos. You
can set the photo part alone as the para-intermediate (gray) tone. For an orig-
inal mainly occupied by photos, to the contrary, you can detect and scan the
original as a whole as the para-intermediate (gray) tone, setting the text part
alone as non-intermediate (gray) tone. The maximum number of ranges to
have partially different setting from the overall setting is 4.
IEEE1394 Interface Unit Type IS760
You can connect your PC to the IEEE1394 Interface board
Two IEEE1394 connectors are available, and you can connect a total of 3 PCs to
this machine together with another SCSI connector equipped.
Limitation
❒
The pre-installed USB 2.0 interface board is to be used exclusively.
Note
❒
You cannot use simultaneously two or more PCs connected. Connection is
automatically switched to either SCSI, IEEE1349-1 or IEEE1349-2.
