Problem 15 Memory becomes insufficient and scanning stops.
Solutions If you configure scanning conditions that use a large
amount of the computer's memory, scanning may stop
because of insufficient memory. Although this depends
on the computer's memory size, the possibility of
insufficient memory increases if any of the following
scanning conditions overlap.
• [Color Mode] is set to [Color]
• A large page size (e.g. Legal) is specified as the
[Page Size]. Alternatively, the page size is set to
[Scanner's Maximum].
• A high resolution (600dpi etc.) is specified for [Dots
per inch].
If an error message appears due to insufficient memory
while scanning is in progress, exit the application,
change the scanning conditions (e.g. reduce the
resolution or page size) and then try scanning again. In
addition, the amount of memory used can be contained
by turning off [Moire Reduction] and [Prevent Bleed
Through/Remove Background] if they are set to on.

with multiple pages.

Problem 17 Passport cannot be scanned as intended
Solutions Depending on the condition of the carrier sheet or
passport, the image may not be scanned completely or
the scanner's image correction may not function
properly.
Configure the settings as shown below.
(1) Set [Page Size] to a larger paper size (A4, for
example) on the scanner driver settings screen,
and then scan again.
(2) Set [Dots per inch] to 300 dpi or less on the scanner
driver settings screen.
(3) Clean the roller.
Problem 18 The size detection and deskew functions fail.
Solutions When [Document Type] is set to [Carrier sheet] in the
[Feeding] tab of the scanner driver settings screen and
you scan a document with black edges without
inserting it in a carrier sheet, the size detection and
deskew functions may fail. In such cases, disable the
size detection and deskew functions, or set [Document
Type] to [Plain paper] in the [Feeding] tab.
