Abstract:
1. A control method for an image forming system that includes first and second image forming devices performing image formation on sheets and at least one post-processing device performing a post processing on the sheets which have been subjected to image formation by the image forming devices, comprising: sorting print jobs into a first print job to the first image forming device and a second print job to the second image forming device; performing image formation on the sheet with the first image forming device; writing attribute information including job information for indicating a post processing to be executed and identification information for identifying a page order of the sheets, in a memory of a radio frequency IC tag affixed to the sheet which has been subjected to the image formation by the first image forming device and which is placed on a first tray of the post-processing device; performing image formation on the sheet with the second image forming device; writing attribute information including job information for indicating a post processing to be executed and identification information for identifying a page order of the sheets, in a memory of a radio frequency IC tag affixed to the sheet which has been subjected to the image formation by the second image forming device and which is placed on a second tray of the post-processing device; reading out with the post-processing device the attribute information from memories of radio frequency IC tags affixed to the sheets in a sheet bundle placed on the first tray and in the sheet bundle placed on the second tray; selectively feeding the sheets from the sheets in the sheet bundle placed on the first tray and the sheets in the sheet bundle placed on the second tray on the basis of the read-out attribute information; and executing the post processing on the fed sheets.
