A processor is provided, the processor including: an obtaining unit that obtains abnormality information related to an abnormality from an image forming device in which the abnormality occurs; an abnormality information storing unit that stores the abnormality information obtained by the obtaining unit as history information; a failure position information storing unit that stores failure position information for each phenomenon related to the abnormality; an extracting unit that extracts the failure position information corresponding to the latest abnormality information and abnormality information similar to the latest abnormality information among the abnormality information stored in the abnormality information storing unit from the failure position information storing unit; and an output unit that outputs an extracted result extracted by the extracting unit as specific deciding information of a cause related to the occurring abnormality.

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.

Image formation apparatus and method therefor

For the line determined by a line feed determining portion 2 to be fed greatly, for the line determined by the line feed determining portion 2 to be fed small and further determined by a printing density determining portion 3 to be printed with a low printing density and, for the line determined by the line feed determining portion 2 to be fed small, determined by the printing density determining portion 3 to be printed with a high density and whose preceding adjacent line is low in printing density, a printing pressure setting portion 4 sets a normal printing pressure. For the line determined by the line feed determining portion 2 to be fed small, determined by the printing density determining portion 3 to be printed with a high printing density and whose preceding adjacent line is high in printing density, the printing pressure setting portion 4 sets a low printing pressure. In consequence, a high density printing cannot be repeated on the same area of the printing form with a high pressure with the result that it can be prevented for wrinkles or breakage to occur on the printing form.
