Method and apparatus for controlling a set paper in an image forming device

A method to control an image forming device, the method comprising:

• setting a type of paper to form an image;
• judging the set type of paper and a current feed mode, wherein if the current feed mode is set as a cassette feed and the set type of paper is judged to be unsupportable by the cassette, converting the set type of paper into a supportable type of paper, which has a fixing temperature similar to that of the set type of paper and is supportable in the cassette, and determining values of fixing temperature and high voltage of the converted type of paper;
• and
• forming an image on a paper fed from the cassette according to the determined values of fixing temperature and high voltage.

A method to control an image forming device, the method comprising:

• setting a type of paper to form of an image;
• judging the set type of paper and a current feed mode;
• generating a warning message if the feed mode is judged to be a cassette feed and the set type of paper is unsupportable by a cassette feed,
• counting a time lapse after generation of the warning message, wherein if the counted time lapse is longer than a set reference time, converting the set type of paper into a supportable type of paper, which has a fixing temperature similar to that of the set type of paper and is supportable by the cassette, and determining values of fixing temperature and high voltage of the converted type of paper;
• and
• forming an image on a paper fed from the cassette according to the determined values of fixing temperature and high voltage.

A controller of an electrophotographic image forming device, having a printer engine, the controller comprising:

• an engine interface;
• a printer controller to provide inputted paper setting data through the engine interface;
• and
• an engine controller to judge a paper feed mode based upon the paper setting data inputted through the engine interface and to judge whether the set type of paper is supported by the image forming device.

A method to control an image forming device, in which a user sets a type of paper, having image forming conditions, the method comprising:

• judging whether the paper is to be fed from a cassette;
• judging whether the set type of paper is supportable by the cassette, if the paper is to be fed from a cassette;
• converting the set type of paper into a supportable type of paper having image forming conditions similar to those of the set type of paper, if the set type of paper is judged to not be supported;
• and
• determining values of the image forming conditions of the converted set type of paper.
