Abstract: An organic light emitting display apparatus including a substrate including a plurality of pixel areas; a pixel electrode on the substrate; an opposite electrode on the pixel electrode, the opposite electrode transmitting light; an organic light emitting layer between the pixel electrode and the opposite electrode, the organic light emitting layer emitting a first light toward the opposite electrode; a light emitting layer on the opposite electrode, the light emitting layer absorbing a portion of the first light and emitting a second light; and a sealing layer on the light emitting layer, the sealing layer sealing the pixel electrode, the opposite electrode, the organic light emitting layer, and the light emitting layer.

Abstract: A method of performing handshaking between fax machines on the basis of T.30 protocol includes transmitting information on a first data rate selected to transmit a fax document to a receiving-side fax machine, transmitting a plurality of frames including bit strings predefined to test data transmission/reception at the first data rate prior to transmitting the fax document to the receiving-side fax machine, and receiving a message informing success or failure of the test. The transmitting of the frames includes determining a time duration of the transmitting the frames based on at least one of a TCF flag value and the first data rate.

Abstract: An image forming apparatus is provided.

Abstract: An image forming apparatus is equipped with a facsimile machine having two or more lines, including a paper feeding unit; an image forming unit; and a discharging unit, wherein if first facsimile information is received through a first line of the two or more lines, the paper on which an image of the first facsimile information is formed is discharged passing through the paper feeding unit, a paper transporting path and the discharging unit in turn, and if second facsimile information is received through a second line of the two or more lines, the paper on which an image of the second facsimile information is formed is discharged passing through a paper returning path, the paper transporting path and the discharging unit in turn after the image of the second facsimile information has been formed.
