Abstract: An image scanning device, an image forming apparatus including the image scanning device, and a method of controlling image quality in the image scanning device are provided. The image scanning device includes a document board on which documents to be scanned are placed, a scanning unit which is installed on a lower portion of the document board to be linearly reciprocated, and comprises a scanner including a light guide for irradiating light to the documents, and light emitting devices that are separated from both ends of the light guide and irradiate light, and an image sensor for receiving the light emitted from the scanning unit, wherein, loss of the light emitted from the light emitting devices is compensated for by increasing intensity of electric current supplied to the light emitting devices as a distance between the light emitting devices and the light guide increases.

Abstract: An inkjet image forming apparatus including an exposure time of ink attached to nozzles is determined considering various factors including a capping/uncapping time of a print head, a time interval of a powering operation, and a time interval of a printing operation, and then a washing mode to be performed is selected out of a plurality of washing modes with different washing methods in accordance with the exposure time of the ink. Therefore, washing of a print head can be performed more efficiently depending on a condition of ink attached to the nozzles. In addition, a viscosity of the attached ink can be weakened by heating the print head while performing the washing mode. Especially, when washing the print head by an ultrasonic washing mode, a washing energy can be concentrated on a removal of the ink, thereby improving washing efficiency.
