Problem 6 Pages are missing.
Solutions When the scanner driver's [Scanning Side] setting is
[Skip Blank Page], documents with very little black may
be unintentionally skipped. Select another scan mode
setting such as [Simplex] or [Duplex], or decrease the
[Ratio of black pixels]. If pages are skipped due to the
document double feeding, see
jam (or double-feed).".
Problem 7 Documents jam (or double-feed).
Solutions (1) Clean the feed rollers if necessary.
(2) Proper scanning may not be possible when
document pages stick together due to static
electricity. Fan the documents before you load them.
Problem 8 Each scanned image of a multi-page document is
saved as a separate document.
Solutions With CaptureOnTouch, you can scan multiple pages
into one image file when TIFF or PDF file format is
selected. To do this, select [File type], click the [Detail
Settings] button, and select [Save all pages as one file]
in the displayed dialog box.
When you select [Scan Batch to File] from the [Scan]
menu in CapturePerfect, a dialog box appears with a
pull-down menu at the bottom that allows you to select
[Single Page], [Multi Page (All Pages)], or [Multi Page
(Specified Pages)]. If you select [Single Page], each
page of a multi-page document is saved as a separate
image file. To save multiple pages to a single image file,
select [Multi Page (All Pages)] or [Multi Page (Specified
Pages)].
Problem 9 Documents feed, but no scanned images are saved.
Solutions When Panel-Feeding is selected as the feeding method
on the scanner driver's setting screen, after a document
is fed, scanning does not occur until the scan button is
clicked on the scan panel.
Problem 10 Scanned images of multiple pages cannot be saved
in a single JPEG or BMP file.
Solutions Multiple scanned images cannot be saved in a single
JPEG or BMP file. Save the images in either TIFF or
PDF format.
