Multi-function machine having jam removing apparatus and jam removing method thereof

A multi-function machine having a printer unit to print data onto a sheet of paper, a scanner unit to read data from a document, and a jam removing apparatus, the jam removing apparatus comprising:

• a first case disposed with respect to the printer unit to form a portion of a paper supply path of the printer unit and having a portion of component parts of the scanner unit therein;
• a second case disposed with respect to the first case to form a portion of a document supply path of the scanner unit together with the first case and having a remaining portion of the component parts of the scanner unit therein;
• a first moving unit to separate the first and second cases apart from the printer unit so as to remove a jammed of sheet of paper when the sheet of paper is jammed in the printer unit;
• and
• a second moving unit to separate the second case apart from the first case so as to remove a jam of document when the document is jammed in the scanner unit.

A method for removing a jammed sheet of paper or document in a multi-function machine having a printer unit to print data onto a sheet of paper, and a scanner unit to read data from a document, comprising:

• separating a first case apart from the printer unit, the first case being disposed with respect to the printer unit to form a portion of paper supply path of the printer unit while a second case is locked with the first case, the second case forming a portion of the paper supply path of the scanner unit together with the first case;
• and
• removing the jammed of sheet of paper from the portion of paper supply path;
• wherein the step of separating the first case apart from the printer unit comprises sliding a case slider installed at the first case along a case moving guide installed at a main body frame.
