The bottom of the scanned image is cut off

The scanner can scan an entire media that is up to 355.6 mm (14.0 inches) long. If an item is longer the end of the document will not be included in the scanned image.

The scanned images have streaks or scratches

After each step, try another scan to see if the streaks or scratches are still apparent. If so, then try the next step.

●Check that the originals are clean and unwrinkled.

●Use a cleaning cloth in the scanner paper path. For more information, see Use the HP paper-path cleaning cloth.

●Clean the scanner glass. For more information, see Clean the scanner glass.

●Clean the feed-roller assembly manually. For more information, see Clean the feed- roller assembly manually.
