Abstract
A method and apparatus for forming an image determine if printing paper is properly picked up, and printing data is transferred to an intermediate transfer belt (ITB). When it is sensed that the printing paper is not properly picked up, picking up the printing paper is retried considering a revolution cycle of the ITB. Thus, the frequency of errors can be decreased, and a user's convenience can be increased because picking up the printing paper is automatically retried whenever mis-pick up occurs instead of displaying an error. Further, wasting of toner is decreased.

1-11. (canceled)
An apparatus for forming an image, comprising:
- a pick up unit to pick up a printing paper;
- a pick up sensing unit to sense if a printing paper is properly picked up by the pick up unit;
- a transfer unit to transfer printing data to an intermediate transfer belt (ITB);
- and
- wherein, if the pick up sensing unit senses that the printing paper is not properly picked up, the pick up unit retries picking up the printing paper according to a revolution cycle of the ITB.
The apparatus of 17, wherein, when the cleaning blade is separated from the ITB, when the pick up sensing unit senses that the printing paper is properly picked up and the printing data is transferred to the printing paper or when an error message that the printing paper is not properly picked up is generated, the cleaning blade is moved to contact the ITB to remove the printing data.
21-24. (canceled)
An image forming apparatus, comprising:
- a pick up unit to pick up a printing medium on which an image is to be formed;
- an intermediate transfer belt (ITB) on which printing data is formed to be transferred to the printing medium;
- a transfer unit to transfer the printing data to the ITB;
- a cleaning blade to remove the printing data from the ITB after the printing data has been transferred to the printing medium;
- and
- a controller to control the transfer unit to control application of the printing data to the ITB, to control the cleaning blade to control removal of the printing data from the ITB, and to control the pick up unit to retry picking up of the printing medium according to a revolution cycle of the ITB or a predetermined number of retries if the printing paper is not properly picked up.
