The printer scans very slowly. Graphics are scanned more slowly than text when
using the Scan to E-mail or Scan to Network feature.
Communication speed becomes slow in scan mode
because of the large amount of memory required to
analyze and reproduce the scanned image.
Scanning images at a high resolution takes more time
than scanning at a low resolution.
Document misfeeds or
multiple feeds occur in the
Automatic Document Feeder
(ADF).
Ensure that the document’s paper type meets the
specifications for the printer. See "Supported Paper
Types" on page 198 for more information.
Check whether the document is properly loaded in the
ADF.
Ensure that the document guides are adjusted
properly.
Ensure that the number of document sheets do not
exceed the maximum capacity of the ADF.
Ensure that the document is not curled.
Fan the document well before loading it in the ADF.
Vertical stripes appear on the
output when scanned using
the ADF.
Clean the ADF glass.
See "Cleaning the Scanner" on page 454.

glass.
Clean the document glass.

the document glass.
