An image forming apparatus is provided. The image forming apparatus may include an image forming unit to print data, a body portion disposed in the image forming unit, a display unit disposed on the body portion to be spaced apart from the body portion at a predetermined interval, and a scan unit disposed below the display unit, and a scan space is formed between the image forming unit and the display unit.

Image forming apparatus and method for controlling the same

Provided are an auto document feeder (ADF), a scanner including the ADF, and a method of controlling auto document feeding. The ADF includes: a feed unit picking up a sheet of paper and carrying the sheet of paper to a scan unit; a feed control unit controlling the feed unit; and a retry control unit. If a sheet of paper is not normally picked up by the feed unit, the retry control unit decreases a speed of a motor driving the feed unit or increases a current supplied to the motor for picking up the sheet of paper. Therefore, although sheets of paper are not normally fed when a user intends to use various kinds of sheets of paper with the ADF, the retry control unit may stabilize feeding of the feeding of the sheets of paper. Thus, efficient, convenient, and high-quality paper feeding may be possible.

Auto document feeder, scanner including the same, and method of controlling auto document feeding

An image scanning apparatus is provided. The image scanning apparatus includes an image sensor configured to scan a manuscript, a sensor driving unit configured to allow the image sensor to move on a scanning path, a driving control unit configured to generate a driving signal for the sensor driving unit, and a control unit configured to control the image sensor to scan the shading patch during moving to scan the manuscript.

Image scanning apparatus and method

A scanner including an automatic document feeder includes a communication interface unit to perform a communication with an external printer; a scan operation performing unit to perform a scan operation; an automatic feeding unit to automatically feed scan-target documents to the scan operation performing unit; and a controller to control the scan operation and a scan speed, wherein when the communication interface unit receives a request speed for a scan operation from the external printer, the controller adjusts a feeding interval between the scan-target documents that are fed from the automatic feeding unit, so that the scan operation is performed at the received request speed.
