Chapter 7 ISIS/TWAIN Driver Settings

[Others] Tab Sheet (TWAIN driver)
[Reverse side]
Scanning occurs as follows depending on the scanning side settings.
☞ When this check box is selected and the scanning side is set to [Simplex], only the back of each
page is scanned.
☞ When this check box is selected and the scanning side is set to [Duplex] or [Skip Blank Page], the
back of each page is scanned first, followed by the front.
[Rapid Recovery System] Check Box
If a paper jam causes paper transport to stop while scanning, scanning stops without sending an
error notification to the application program. After fixing the cause of the stoppage, you can continue
scanning with the standard operations.
[JPEG Transfer] Check Box
When this check box is selected, scanned image data is always compressed to JPEG format within
the scanner for output to the computer.
Scanned image data is output from the scanner as an uncompressed or JPEG transfer, depending
on instructions from the ISIS/TWAIN driver or application program.
☞ Uncompressed transfers output raw scanned image data, so when the image data is large,
significant time may be required for transfer from the scanner to the computer.
☞ JPEG transfer is good for color and grayscale images, as scanned image data is JPEG-
compressed within the scanner before output.
This reduces the size of the image data for output, so transfer time from the scanner to the
computer is shortened.
When JPEG Transfer is selected, image data from the scanner is always output as JPEG-
compressed data.
☞ When the uncompressed saving format is selected in the application program, JPEG-compressed
image data is reconverted to uncompressed data before transfer to the application. Image quality
is degraded slightly as a result.
☞ This check box setting is ignored if the application program requests a JPEG transfer.
☞ Of course application program requests depend on the specifications of the particular program.
