Symptom 16:

Trouble scanning with Multi-Scan or Multi-Crop function
  Cause 1: Photos (items) positioned outside the supported area.
  Solution: Check the position of the photos on the document glass. Observe the following when using the Multi-Scan or Multi-crop function.
* Leave at least 1 cm (1/2 in.) between items.
* Leave at least 1 cm (1/2 in.) between the items and the document glass's sides and front edge.

Leave at least 2 cm (1 in.) between the items and the document glass's back edge.

* A maximum of 10 items can be scanned at once.
* If an item is slightly crooked on the platen-within 10 degrees of true-the image is automatically straightened.
* The Multi-Scan function only supports rectangular photos and items.
* Non-rectangular photos (irregularly shaped, close-cropped photos) cannot be detected correctly.
  Cause 2: Error arising from application program specifications.
