Scanning performance issues

Scanner does not scan right away

Make sure the document feeder hatch is closed, and that the scanner is turned on.

Scanner scans only one side of a two-sided page

Verify that the selected scan shortcut speciﬁes two-sided scanning.

Scanned pages are missing at the scan destination

When scanning, pages that stick together are scanned as one item. Check to conﬁrm that scanned pages are not

stuck together.

Scanned pages are out of order at the scan destination

●

Verify that the page order of the original document is correct before placing the document face down into

the document feeder.

●

Make sure that there are no staples, paper clips, or any other attached material (such as adhesive notes)

that may cause the pages to feed incorrectly.

●

Verify that pages are not stuck together.

Scan ﬁles are too large

●

Most scanning software allows a smaller ﬁle size to be selected when selecting the output ﬁle type. For

more information, see the Help for the scanning software being used.

●

Verify the scan resolution setting (for more information, see the Help for the scanning software being

using):

–

200 dpi is suﬀicient for storing documents as images.

–

For most fonts, 300 dpi is suﬀicient for using optical character recognition (OCR) to create editable

text.

–

For Asian fonts and small fonts, 400 dpi is the recommended resolution.

Scanning at a higher resolution than necessary creates a larger ﬁle with no additional beneﬁt.

●

Color scans create larger ﬁles than do black and white scans.

●

If scanning a large number of pages at one time, consider scanning fewer pages at a time to create more,

smaller ﬁles.
