Apparatus, system for forming image, and method for controlling image forming apparatus

A system for forming an image comprising

• an information processing apparatus for inputting an original image and image forming processing information including at least information about the image formation sheet number, and
• an apparatus for forming an image including:
• a controller receiving the original image and the image forming processing information from the information processing apparatus;
• a plurality of paper supply sections having a paper size sensor to detect a size of a print paper set on;
• an image forming section forming an image on the print paper fed from the paper supply sections, based on the original image;
• a paper discharge section to stock the print paper formed of the image and discharged;
• an auto fence located on the paper discharge section, to displace the position of a width direction of the print paper stocked on the paper discharge section according to the paper size of the print paper fed from the paper supply sections;
• a storage section to store the image forming processing as the printing job in the image for one page unit;
• and
• a control section determining a sequence of each printing job stored in the storage section so that printing processing is executed in order from a printing job with the smallest paper size in the width direction of the print paper.

A method for controlling an image forming apparatus, the method comprising:

• detecting a size of a print paper set on a plurality of paper supply sections;
• storing image forming processing as the printing job in the image for one page unit in a storage section;
• determining a sequence of each printing job stored in the storage section so that printing processing is executed in order from a printing job with the smallest paper size in a width direction of the print paper;
• and
• displacing of the position of the width direction of the print paper stocked on the paper discharge section according to the paper size of the printing job, feeding the print paper from the paper supply sections, forming an image on the print paper fed from the paper supply sections in an image forming section, and discharging and stocking the print paper formed of the image on a paper discharge section, are executed according to the sequence.
