  • Patent number: 9386168
    Abstract: According to one embodiment, the media reuse determination apparatus has a decoding section, a reusability determination section, and an output section. The decoding section decodes information related to management of a print media attached to the print media obtained by using a reading apparatus to read the object having the information recorded thereon, and it carries out error correction during decoding of the information. On the basis of the result of the error correction carried out during decoding of the information by the decoding section, the reusability determination section determines whether or not the print media can be reused. The output section outputs the result of the determination made by the reusability determination section.

  • Patent number: 8970932
    Abstract: A decolorizing device includes a first reading section, a decolorizing section, a second reading section and a controller. The first reading section reads a first side of the sheet. The decolorizing section performs a decolorizing process on the sheet and the second reading section reads the first side of the sheet. The controller is configured to determine if the decolorizing process is necessary or not on the first side based on first image data of the first side read by the first reading section, to read the first side of the sheet having been subjected to the decolorizing process at the decolorizing section by the second reading section if it is determined that the decolorizing process is necessary, and to avoid reading of the first side of the sheet by the second reading section if it is determined that the decolorizing process is unnecessary.

  • Patent number: 8934141
    Abstract: A system includes a receiving unit and a controller. The receiving unit receives data about the number of processes performed in an image forming unit to form an image with a decolorable color material and data about the number of processes performed in a decolorizing unit to decolorize an image formed with the decolorable color material. Based on the data received by the receiving unit the controller calculates the number of media in user's use in a condition after they are subjected to image formation by the image forming unit and before they are decolorized by the decolorizing unit. The controller deters image formation by the image forming unit if the number of the media in user's use exceeds a first threshold, and allows the image forming unit to form an image if the number of the media in user's use does not exceed the first threshold.
