Problem Possible Solution
(ADF) The document has been loaded
on the feeder tray, but the scanner does
not start scanning.
• The document is not loaded properly. See the section entitled,
“Scanning documents” in Chapter 3.
• The sensor cannot detect the document because the edge of the
document is curled. Flatten the document and load it again. See the
section entitled, “Getting your documents ready to scan” in Chapter 3.
(ADF) Double feeding or skewing
problems occur frequently or the
scanner stops feeding while scanning.
• The rollers may be dirty or have reached their life expectancy. Clean
the rollers and examine them for wear. See Chapter 6, Maintenance for
cleaning and replacement procedures.
• The document is curled for folded. Flatten the document, reduce the
number of sheets in the feeder tray and load the document again.
(ADF) Scanned image is skewed.
• Be sure the document guides are adjusted to the size of the documents
being scanned.
• Verify that the document to be scanned is straight in the feeder tray.
• The right and left sides of the document to be scanned are not the
same height because of curls and folds. Remove the curls or folds,
reduce the number of sheets in the feeder tray and load the document
again.
For 3210 Scanner only:
• An irregular type of document needs to be scanned. Use the flatbed to
scan the document.
• The document length is less than 2.75 in (70 mm). Use the flatbed to
scan the document.
(ADF) The scanned document is blank. Verify that the document to be scanned is positioned correctly in the
feeder tray. Documents should be placed in the feeder tray face-up.
Vertical lines appear on the scanned
document.
Clean the imaging guides (or flatbed glass) and background bars. See
Chapter 6, Maintenance for cleaning procedures.
The scanning density is uneven. • Clean the imaging guides (or flatbed glass) and background bars. See
Chapter 6, Maintenance for cleaning procedures.
• Perform a shading adjustment. See Chapter 5, User Utility (User
Shading) for more information.
The color of the scanned document is
very different from the original
document.
Adjust the computer display and monitor settings.
Dark spots or noise appear on the
scanned documents.
Clean the imaging guides (or flatbed glass) and background bars. See
Chapter 6, Maintenance for cleaning procedures.
Scanned image has moire fringes or
patterns, such as stripes or wavy
pattern noise.
This is caused by the original printing pattern on the document and the
selected scanning resolution. Change the scanning resolution, then scan
the document(s) again.
Image crop failures with VRS scanning. Paper or dust may be on the background bars. Examine and clean the
background bars. See Chapter 6, Maintenance for cleaning procedures.
