An image formation apparatus that includes plural paper feed trays, and when there occurs out-of-paper in a paper feed tray during printing, changes over from the paper feed tray to another to continue the printing, which includes a detection section that detects that paper is added in the paper feed tray, a memory that stores paper feed trays for which the detection section detects that paper is added therein in the sequence of paper being added; and a paper feed tray changing section that, when there occurs out-of-paper in a paper feed tray in operation during printing, selects a paper feed tray in which paper is added in the earliest time among the paper feed trays which are stored in the memory, and changes over the paper feed tray.
An image formation apparatus comprising:
An image formation method being implemented by an image formation apparatus, the image formation apparatus comprising a plurality of trays, a memory, and a tray changing section, each tray of the plurality of trays for feeding paper to the image formation apparatus, each of the plurality of trays for feeding paper including a paper-addition-determination portion, the image formation method comprising:

1. Field of the Invention
The present invention relates to an image formation apparatus which has a function of relay paper feeding that, when there occurs out-of-paper in a paper feed tray, selects another paper feed tray for paper feeding to continue the printing, and a method therefor, and particularly relates to an image formation apparatus which, at the time of paper feed tray selection in the relay paper feeding, selects the paper feed tray having the earliest date of paper addition to continue the printing, thus preventing old paper from being left over at the bottom of the paper feed tray, and a method therefor.
