Abstract
An automatic document feeder includes a document loading detector, a document feeder, a document guide, a guide width measurer, a document width acquirer, a guide shift determiner, a document skew detector, a skew determiner, a warning display information generator, and a display. When a detected skew of a document is determined to be unallowable, the document feeder stops a feeding of the document. The warning display information generator generates a warning content about a feed trouble that stopped the feeding of the document, and the generated warning content about the feed trouble is displayed on the display.
