Jam removing device and image forming apparatus including the same, and jam removing method

A jam removing device of an image forming apparatus, the image forming apparatus comprising:

• a cover unit to selectively open and close;
• an image forming unit to form an image on a sheet of paper conveyed along a feed path by a pickup roller;
• a discharging unit to discharge the paper from the image forming apparatus along a discharge path;
• and
• a driving source to drive the discharging unit, and the jam removing device comprising:
• a jam detecting unit, mounted on the feed path and the discharge path, to detect a jam of the paper in the image forming apparatus;
• a drive controlling unit to drive the driving source for a predetermined amount of time by opening of the cover unit;
• and
• a pickup determining unit to determine selectively performing a pickup operation by the pickup roller according to a detected location of the jammed paper.

A jam removing method of an image forming apparatus, comprising:

• detecting a jam of the paper in a conveying path of the image forming apparatus, the conveying path comprising a first path and a second path;
• driving a driving source of a discharging unit of the image forming apparatus for a predetermined amount of time, in response to the jam of the paper occurring in the conveying path of the image forming apparatus;
• selectively performing a pickup operation by a pickup roller of the image forming apparatus, according to a detected location of the jammed paper relative to the first and second paths, in response to driving the driving source for the predetermined amount of time;
• and
• discharging the jammed paper from the image forming apparatus by the discharging unit.
