Blurry Scans, Vertical Banding, or Misalignment
The originals are folded or wrinkled.
Solutions
❏ When using the ADF
Do not place the originals on in ADF. Place the originals on the scanner glass instead.
❏ When using the scanner glass
Flatten out the folds and wrinkles in the originals as much as possible. When placing originals, try
placing a piece of card and so on over the document so that it does not li up, and remains in close
contact with the surface.
